Service Project Title: Organization process simulated with the generic "The G-8 - has a higher obligation to combat climate change.
Dates of Service Project: 21 March 2009
In one sentence, describe your service project goal.
We are going to discuss the developed leadership position in a simulated judicial process and to submit suggestions for improving the world environment and state.
What will be your message to people who participate in your service project (focus on being positive!)?
We propose you a simulated judicial process draft which includes the fallowing characters:
Judge
Prosecutor
Defense lawyer
Court clerk
Witnesses
Prime juror
There are the judge's table, the Secretary’s table, two lawyers tables and accused box (here are "Heads of governments of Member G-8) on the scene. Spectators will form the judging process and the first juror will be a previously appointed student. People present at the simulated judicial process will listen to the prosecution of developed countries governments, reveling of G-8 Member attitude towards the environment. G-8 became guilty of climate change processes through excessive use of natural resources and environmental pollution. We want that our discussions bring into light the mistakes committed by governments of developed countries and the economical operators, also, their attempts to prevent the global warming, in the order that the sentence will be right. We listen to both defendants and defenders very carefully and we consider only those samples, examples, testimonies that are based on truth. We will proceed, continue to hear witnesses.

Defendants:
Witness 1: Your Honor! I blame the governments of developed countries (USA, Canada, Germany, Great Britain, France, Italy, Japan, and Russia) which have not taken measures for the prevention of global warming. Please note that, governments of developed countries have approved programs of economic development, ignoring the consequences of environmental pollution on climate change. -Your Honor! Ask them if they have complied with the promises. I require punishment because the government did not respect the commitments and for the damage caused to nature. Analyzing the statistics in the media and the Internet, I asked myself whether the governments are aware of the need for urgent measures to prevent the greenhouse effect, climate change etc…
Witness 2: Honor! I blame not only the governments of developed countries but also managers of companies, as they only think of profits, they use the huge opportunities offered by nature, but do not undertake anything to improve the ecological environment. Please allow me to introduce appropriate records.
Defenders:
Witness 3: Your Honor! I consider that governments of developed countries do not have a grater blame for climate change as the less developed countries. This is a problem of previous governments adding the fact that climate change took place also caused by the changes in universe. If you compare the developed and less developed countries, namely the first ones use more environmentally friendly technologies and costs for scientific researches and educational programs.
It is true that the governments of the developed countries also bear the responsibility of climate changes, but I think that everyone should be responsible for this huge problem of our planet because each contributes to environmental pollution.
Witness 4: Honor assistance! I blame the legal and international organizations which do not take measures correctly and when they should be taken to punish the guilt of environmental pollution. The fines are low and for economical agents are more convenient to pay them than to invest in environmental technologies.
I require that all representatives of the governments of G-8 be removed under the accusation.
The accused and the defenders answer the questions of the prosecutor to clarify the status of things. The representatives of the governments of developed G-8 that puts forward their position against the controversial discussions and propose solutions to combat climate change are listened to, too.
President: Your Honor! We have listened to charges and defenders affirmations towards the governments of G-8 members and I come with the following decision:
I recognize that much has been done and there is still something undertaken to combat climate change, but there are many reservations to improve ecological status of our planet. I consider that along G-8; can be accused and other states, too. But I still consider that the developed countries have a greater obligation to contribute to the fight against global warming.
So, as a result of the discussions we have assisted, met today, 30 March 2009, the High Court

DECIDES:
1.Imposition of the total extinction of the facts as: indifference to the environment, promises made in vain, pollution actions.
2. Developed countries should develop a set of measures to combat climate change:
- Governments of developed countries will propose concrete measures to reduce substantially the quantity of gas from transport and factories thrown into the atmosphere;
- Governments should help the less developed countries to use new technologies and to train the entrepreneurs, also they should create investment funds of long standing. This will curb environmental pollution, spreading of diseases, forest fires, glacier melting, droughts and floods;
- Governments of the developed countries should strongly contribute to promoting democratic principles and human rights, transparency and accountability of governments and citizens;
- Governments of the developed countries should take measures to curb climate change processes that will lead to reduction and even disappearance of species and animals;
- Granting more funds for scientific research and practical actions in all countries to reduce dumping gas into the atmosphere;
- Use of transport-based biofuel, according to the current limitation of energy resources, which contributes greatly to environmental pollution;
- Developing technologies to prevent climate change, gas collection and conservation, waste, prevent accidents and disasters;
- Intensive planting of forests, the environmental actions in all states.
Measures of success: List three ways you will know that your project was successful
We believe that the judicial simulated process will have success, because it will deal with the current problems of climate change and will propose concrete measures to resolve environmental problems:
a) The thorough study of the literature and existing sources with reference to improve the environment.
b) Within the framework of this project will be involved high school students and other pre-university educational institutions, teachers, scientists from the Academy of Sciences of Moldova, journalists, students, parents and friends;
c) As a result of the our activity a message to world governments will be drew up to project measures to combat climate change;
d) The participants of the simulated judicial process will plant an alley of trees, which will become living witnesses of climate change in the future;
e) Students and adults will have the possibility to communicate effectively with reference to global environmental problems, as well as to those local and will propose solutions for improvement;
f) Students will organize a photo exhibition of materials, from magazines and internet, which will elucidate the environment and will sensitize the participants to work on environmental problems;
g) There will hold a press conference with representatives of developed governments countries that will propose solutions to combat climate change in the coming 10-15 years.
Describe how your service project takes your debate and makes it actionable.

The information presented in the judicial process will be useful in organizing public debates, but also in involving young people in studying environmental issues and proposing concrete ideas for solving the environmental problem of the community.
Also such activities will be organized at other school subjects. Students who were involved in work experience will send their research problem, and discuss other environmental issues in a round table and training other colleagues, where they will invite their friends and their parents, and community members, too.
The period of time March-April is designated for a number of actions in the bi-monthly environmental (planting trees, cleaning of parks, territories, the eve of aquatic ecology activities in rural areas, public debates etc..
What resources do you need to make it happen? Where will you get them?
Project resources will be used for planned budget, but the local economic agents will be asked to support young people, using volunteer labor, the parents etc.
List five ways you will engage your community - friends, family, neighborhood, city, school etc.
All participants of this activity will be motivated to participate with interest and help in practical undertaken activities. Owing to the fact that these participants make a single united team they will contribute to the strengthening of the image of the school community, family and will establish partnership relations with other organizations and state structures and NGO.
As part of activity, but also in the preparation stage we will apply to the help of specialists in the field at the Academy of Sciences of Moldova (Chairman - Mr. A. Duca), workers from the National Institute of Ecology (director Mr. D. Drumea), specialists in the field from the Ministry of Ecology, which will contribute to the review and evaluation of projects as well as the corrections for further improvement.
Mostly, the participants classmates will be motivated to participate in organizing and conducting the project, because they have a moral obligation to support colleagues and that is a lesson of life. They will present project ideas and ways of applying them in the community, and the results will be discussed in other activities. Their classmates will help to arrange the room, fixing furniture, etc.
Friends involved in this activity will contribute to taking pictures and making materials, posters and others.
We are convinced of the contribution and assistance of family members who will support the moral and financial part of the costs for project implementation, will participate actively in the implementation phase of projects.
We believe that the project will succeed if we will attract and motivate community members who will engage in supporting the completion of projects in the city.
The initiative at the Academy of Sciences of Moldova competition will ensure project continuity in the future.
How will you make sure that what you do on the day of your service project has a lasting effect?
The proposed project will have a successful lasting effect because:
- Students participating in the project will gain necessary skills for discussion and analysis of ecological problems, which they later use in organizing and implementing other projects in the community. Students participating in the activity will be stimulated in producing materials for completing the e-portfolio: communication thematic, drawings, pictures, videos, projects, letters, steps, articles etc.
- More than 10 students will work on a scientific thesis, which where will be studied topics related to environmental change, environmental education, education on law, etc..
- There will be formed groups of students who will participate in competitions and school Olympiads, municipal, republican and international issues related to global environment especially ecological ones;
- There will be prepared requirements addressed to specialists in the field, responsible for local bodies to find the key of environmental problems.
List the groups in your area that work to raise awareness and take action on your issue of focus. Will you collaborate with any of these groups? If so, how? If not, what are you doing that no one else is doing?
As a farther step we will work with several interest groups. Firstly, we will get involve in our activity young school people and pre-university students in the presentation and implementation of this projects which has environmental content, which we hope that will be supported by the government that will help to mobilize young people to achieve designed actions.
We are convinced that we will strengthen the partnership with NGO, local government that we expect to support the projects through the allocation of resources for its achievement;
We will work with specialists in the field at the Academy of Sciences of Moldova, who will present us necessary information and materials in research of environmental issues. In addition we hope that they will provide lessons for students, with references to environmental problems. In our actions we will alert the media correspondents, we will ask for help in writing and publishing articles and summaries about environmental activities in school and community.

Global warming uf obligation developed countries to combat climate change

ARGUMENT:

“It is man-made and it is essentially [caused by] fossil fuel burning,

Increased methane production… and so on.”

(Professor David King).

Climate change is happening and humans are contributing to it! No one disputes that Earth’s climate is changing or that atmospheric concentrations of greenhouse gases have increased as a result of human activities. The concentrations of carbon dioxide, methane, and nitrous oxide are higher now than at any time during the last 420,000 years.

Overwhelming scientific evidence supports the conclusion that observed changes in the global climate are, in large part, due to human activities and primarily related to fossil-fuel consumption patterns. Without urgent action to curb greenhouse-gas emissions, the Earth will become warmer by 2050 than at anytime in the last 10,000 years.

Temperatures provide the clearest evidence that the climate is changing and globally the average temperature has risen by more than 0.7 °C over the last 100 years.
The natural greenhouse gas effect keeps Earth much warmer than it would otherwise be, without it Earth would be extremely cold. Greenhouse gases such as carbon dioxide, methane and water vapor behave like a blanket around Earth. These gases allow the Sun’s rays to reach Earth’s surface but impede the heat they create from escaping back into space.

Any increases in the levels of greenhouse gases in the atmosphere mean that more heat is trapped and global temperatures increase - an effect known as ‘global warming’.

There is indisputable evidence from observations that the Earth is warming. Concentrations of CO2, created largely by the burning of fossil fuels, are now much higher, and increasing at a much faster rate, than at any time in the last 600,000 years. Because CO2 is a greenhouse gas, the increased concentrations have contributed to the recent warming and probably most of the warming over the last 50 years..

The rise in global surface temperature has averaged more than 0.15 °C per decade since the mid-1970s. Warming has been unprecedented in at least the last 50 years, and the 17 warmest years have all occurred in the last 20 years. This does not mean that next year will necessarily be warmer than last year, but the long-term trend is for rising temperatures.

A simple mathematical calculation of the temperature change over the latest decade (1998-2007) alone shows a continued warming of 0.1 °C per decade. The warming trend can be seen in the graph of observed global temperatures. The red bars show the global annual surface temperature, which exhibit year-to-year variability. The blue line clearly shows the upward trend, far greater than the uncertainties, which are shown as thin black bars. The recent slight slowing of the warming is due to a shift towards more-frequent La Niña conditions in the Pacific since 1998. These bring cool water up from the depths of the Pacific Ocean, cooling global temperatures.

The purpose of the research: The ample studying of the projects from the ecological problems compartment, especially those concerning climate change and its influence on Earth’s future.

The current climate change is not just part of a natural cycle. Earth’s climate is complex and influenced by many things, particularly changes in its orbit, volcanic eruptions, and changes in the energy emitted from the Sun. It is well known that the world has experienced warm or cold periods in the past without any interference from humans. The ice ages are good examples of global changes to the climate, and warm periods have seen grapes grown across much of Britain.

Over the several hundred thousand years covered by the ice core record, the temperature changes were primarily driven by changes in the Earth’s orbit around the Sun. Over this period, changes in temperature did drive changes in carbon dioxide (CO2). Since the Industrial Revolution (over the last 100 years), CO2 concentrations have increased by 30% due to human-induced emissions from fossil fuels. The bottom line is that temperature and CO2 concentrations are linked. In recent ice ages, natural changes in the climate, such as those due to orbit changes, led to cooling of the climate system. This caused a fall in CO2 concentrations which weakened the greenhouse effect and amplified the cooling. Now the link between temperature and CO2 is working in the opposite direction. Human-induced increases in CO2 are driving the greenhouse effect and amplifying the recent warming.

The Earth is heated by the sun; solar radiation passes through the atmosphere and is absorbed at the Earth’s surface (except for a small portion that is reflected back into space). This heat is readily lost; it is emitted from the surface as infra-red radiation. Fortunately, this infra-red radiation cannot escape the atmosphere as easily as the solar radiation can enter. Instead, some of it is ‘trapped’ by a number of gases; these gases act in a similar, yet different, way to the glass in a greenhouse - heat is allowed in but cannot get out - hence we have the ‘Greenhouse Effect’. Were it not for this natural greenhouse effect the Earth would be at least 30°C cooler and life as we know it would not exist. Unfortunately, recent human activities are enhancing the natural greenhouse effect. The concentrations of certain greenhouse gases in the atmosphere are increasing therefore more of the infra-red radiation emitted by the Earth’s surface is being trapped. The planet is losing less heat and as a result we are beginning to experience “Global Warming”. The major greenhouse gases are: water vapor, carbon dioxide, methane, nitrous oxide, CFCs (and their replacements), and ozone. Some of these occur naturally, some result only from human activity, while others occur both naturally and as a result of human activity. The contribution of each gas to the greenhouse effect is a function of three factors: Atmospheric lifetime - simply, how many years the gas remains active in the atmosphere; Global warming potential (GWP) - a relative measure of how effective the gas is at preventing the passage of infra-red radiation; Atmospheric concentration - usually measured in parts per million.

If we continue emitting greenhouse gases this warming will continue and delaying action will make the problem more difficult to fix. The global average temperature will increase by 2 to 3 °C this century – according to one of the Intergovernmental Panel on Climate Change’s (IPCC) mid-range estimates (blue line on the graph below). This rise in temperature means that the Earth will experience a greater climate change than it has for at least 10,000 years and it would be difficult for many people and ecosystems to adapt to this rapid change.

A major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation. Coal is the major fuel that is burnt in these power plants. Coal produces around 1.7 times as much carbon dioxide per unit of energy when flamed as does natural gas and 1.25 times as much as oil. The coal gives out eighty percent more carbon per unit of energy it produces as compared to natural gas. Another major source of carbon dioxide in the atmosphere is the emission from the cars and other vehicles. About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles. This is true for most of the developed countries. Moreover if sports bike and vehicles that are essentially designed for rough terrain, emit more carbon dioxide when used for general purpose on roads.

It is always better to use vehicles designed for city driving on the city roads. Buildings, both commercial and residential represent a larger source of global warming pollution than cars and trucks. Building of these structures requires a lot of fuel to be burnt which emits a large amount of carbon dioxide in the atmosphere.

The second major greenhouse gas after carbon dioxide, which causes global warming, is Methane. Methane is more than 20 times as effectual as CO2 at entrapping heat in the atmosphere. Methane is obtained from resources such as rice paddies, bovine flatulence, bacteria in bogs and fossil fuel manufacture. Almost in all parts of the world, rice is grown on flooded fields. When fields are flooded, anaerobic situation build up and the organic matter in the soil decays, releasing methane to the atmosphere. Nitrous oxide, which is a colourless gas with a sweet odour, is another green house gas. The main sources of nitrous oxide include nylon and nitric acid production, cars with catalytic converters, the use of fertilizers in agriculture and the burning of organic matter. Greater emissions of nitrous oxides in the recent decades is leading global warming

Another major cause of global warming is deforestation. Deforestation is to be blamed for 25% of all carbon dioxide release entering the atmosphere, by the cutting and burning of about 34 million acres of trees each year. Trees collect the CO2 that we breathe out and give away from various other sources, and they give back oxygen that we breathe in. Thus, cutting of trees is leading to greater concentration of carbon dioxide in the atmosphere. Greater urbanization, requirement of land for factories and buildings, requirement of timber are all reasons that are leading to deforestation, which in turn is leading to global warming.
These temperature increases are likely to result in an increased frequency and severity of weather events such as heat waves, storms and flooding. Rising levels of greenhouse gases in the atmosphere could set in motion large-scale changes in Earth’s natural systems. Some of these could be irreversible - the melting of large ice sheets will result in major consequences for low-lying areas throughout the world

Conclution:

Are the developing countries responsible for global warming?

To answer the above question the need to understand the concept of Global warming, its consequences, steps taken to curb global warming and the contribution of the developing nations towards the same. Developing countries including China and India were asked to set voluntary targets for greenhouse gas emissions. Contribution of the developing nations: The US and Australia have refused to ratify the Kyoto protocol, arguing it would damage their economy. Developing countries also argue that they should not be denied the right to develop their economies, which inevitably means an increase in energy consumption. They also say that the burden of responsibility for current climate change lies with developed nations, whose industrial activities over the past century are largely blamed for increasing concentrations of greenhouse gases in the atmosphere. The question today is: Are only the developing countries responsible for global warming?

Subject: The G8 has a huge historical responsibility for causing climate change

Developed countries frequently outsource manufacturing/emissions to developing countries. For this reason, developed countries should not be treated on equal terms, and developing countries should be given exemptions for the dirty outsourcing for foreign countries. China has complained, on this point, that it is "the place where the US effectively outsourcers much of its pollution." It has called for joint international responsibility for at least part of China's emissions, and has made public, in Jan 2008, 130 violations of Chinese environmental law committed by multinationals in China. Other developing countries have a similar problem, in which they are accused of polluting too much, when they are merely the manufacturing engine of developed countries that outsource to them.

Introduction

Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as it radiates back into space. As the greenhouse gases build up in the atmosphere the Earth gets hotter.

One of the main greenhouse gases is carbon dioxide (CO2). As trees grow they take in CO2 from the air. When the wood dies the CO2 is returned to the air. Forest clearance and wood burning (such as happens in tropical rain forests) is increasing the latter half of the process, adding to the CO2 in the atmosphere. Deforestation is now out of control. For example in 1987 an area of the Amazon rain forest the size of Britain was burned, adding 500 million tones of CO2 to the atmosphere. The loss of the forests also means that there are fewer trees to absorb CO2. The recent fires in Indonesia, with more than a million hectares of forest ablaze, thanks to fires set deliberately by logging companies, are likely to have an effect on global climate, but the more immediate effect has been the cloud of smog which enveloped much of south-east Asia during September and early October 1997. However, as large a contribution as deforestation makes, it causes less than half the yearly total of CO2 , the rest comes from the burning of coal, oil and other fossil fuels.

These fossil fuels are burned in cars, power stations and factories of the wealthier nations such as the USA, Western Europe and the USSR. Televisions, lights and computers use electricity that is created mainly from burning coal. Every time we switch on a light we are adding to the greenhouse effect. Cars are also major sources of CO2. The average European is responsible for nearly 2.5 times as much atmospheric carbon as a Latin American. The concentration of CO2 has increased 25% since the industrial revolution; half of this rise has been in the last 30 years. It is expected to double within decades. When sunlight reaches Earth's surface some is absorbed and warms the earth and most of the rest is radiated back to the atmosphere at a longer wavelength than the sun light. Some of these longer wavelengths are absorbed by greenhouse gases in the atmosphere before they are lost to space.

The absorption of this longwave radiant energy warms the atmosphere. These greenhouse gases act like a mirror and reflect back to the Earth some of the heat energy which would otherwise be lost to space. The reflecting back of heat energy by the atmosphere is called the "greenhouse effect". The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide CO₂, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydro fluorocarbons, per fluorocarbons and chlorofluorocarbons. Greenhouse gases in the atmosphere (see above) act like a mirror and reflect back to the Earth a part of the heat radiation, which would otherwise be lost to space. The higher the concentration of green house gases like carbon dioxide in the atmosphere, the more heat energy is being reflected back to the Earth. The emission of carbon dioxide into the environment mainly from burning of fossil fuels (oil, gas, petrol, kerosene, etc.) has been increased dramatically over the past 50 years, see graph below.

Increasing global temperatures are causing a broad range of changes. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Amounts and patterns of precipitation are changing. The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased (in addition, there has been a high correlation of hurricane power with tropical sea-surface temperature).

Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes. Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions. As a further effect of global warming, diseases like malaria are returning into areas where they have been extinguished earlier.

Although global warming is affecting the number and magnitude of these events, it is difficult to connect specific events to global warming. Although most studies focus on the period up to 2100, warming is expected to continue past then because carbon dioxide (chemical symbol CO₂) has an estimated atmospheric lifetime of 50 to 200 years.

Success or failure in any effort to effectively confront global climate change will hinge on a truly global solution to reducing emissions worldwide. That requires U.S. leadership to take the necessary first step to cut our own greenhouse gas emissions at home as we meaningfully engage those developing nations that are least responsible and least equipped to cope with the adverse effects of climate change. Yet given the global nature of climate change, it is also essential that all of the largest greenhouse gas-emitting nations—developed and developing countries alike—commit to reducing emissions.

The path forward to engaging developing countries is clear—the United States must commit to binding greenhouse gas emissions reductions immediately. At the same time, we must provide adaptation assistance to enable poorer and more vulnerable developing countries to deal with the disproportionate costs of global warming on the developing world, and, on an appropriate timeline, urge major emitting developing economies to make commitments to reduce their own greenhouse gas emissions.

Against this backdrop, the Energy and Air Quality Subcommittee of the House Energy and Commerce Committee today convenes a timely hearing focused on how best to engage developing countries through a new international climate regime that prices the cost of polluting into the price of manufactured goods. The subcommittee is particularly interested in examining the potential effect of a U.S. carbon cap-and-trade program on the competitiveness of American products in international markets.

Several greenhouse gas-intensive industries in the United States, such as aluminum, cement, iron, steel, and glass, have expressed legitimate concern that their products will be placed at a competitive disadvantage if developing countries not participating in an international climate regime (with its potentially higher costs of production associated with carbon limits) are allowed to import cheaper products into the United States. Workers in these industries not surprisingly share these concerns.

In response, numerous unilateral trade-related measures have been proposed as a means to level the competitive playing field for U.S. industry. Trade measures, however, can be a powerful but blunt tool for addressing competitiveness issues. It is worth bearing in mind that our trading partners are likely to respond to our proposals with corresponding enthusiasm for reciprocal measures taken against U.S. products, and for protecting their own domestic industries.

The upshot: Our efforts to utilize unilateral trade measures to engage developing countries must be carefully and cautiously constructed, implemented as a last resort, and based on core principles consistent with our existing international obligations.

It is important to slow the warming as much as possible. This means using less fossil fuel, eliminating CFCs altogether, and slowing down deforestation.

This can be achieved best through energy conservation, including better use of public transport and cleaner, more efficient cars; and energy efficiency by greater use of gas which produces less CO2 than coal and oil, and through renewable energy such as solar power. We need to stop destroying rain forests (deforestation) and start replanting trees (afforestation) to soak up carbon dioxide.

A United Nations panel has estimated that we need to reduce global fuel use by 60% immediately in order to stabilise the climate. Current commitments by those governments participating in CO2 reduction will only lower global CO2 by 4 - 6%. Although the developed industrialised nations still produce most CO2, the rapidly developing nations of South America and Asia are increasing their CO2 production at a much higher rate, and by 2010 they will overtake the West as the main producers of CO2.

The developing countries are reluctant to participate in any CO2 emission reduction plans, arguing that they did not create global warming and that it is the responsibility of developed countries to cut their own emissions or to support developing countries with financial aid. Oil producing countries - including a significant lobby in the US - are also reluctant to have their sales reduced and have protested against action on climate change.

Conclusion

The U.S. approach to engaging developing countries in reducing global greenhouse gas emissions must be proactive and comprehensive. As a necessary first step, the United States has a responsibility to demonstrate leadership and commit to binding greenhouse gas emission reductions. A higher priority must be placed on incorporating adaptation assistance into overall U.S. climate strategy at the domestic and international levels.

Trade-related measures to address competitiveness concerns at home must be used cautiously and with restraint. Measures should be narrowly targeted to address only greenhouse gas-intensive products widely traded in the global economy. Finally, the United States must redouble its efforts to encourage the transfer of clean technology and capacity-building assistance to developing countries while seeking cooperation with our trading partners to make the rules of the WTO multilateral trade regime more flexible.

The efforts of the United States to combat global warming and engage developing countries must not be contingent on the actions of other nations. We must never use the relative progress of other countries at different levels of development and in different circumstances as an excuse for our own inaction. The United States has the capacity and know-how today to cut our emissions and assist developing country adaptation to climate change and participation in reducing emissions on a global scale.

We can and will accomplish these goals while preserving U.S. competitiveness in greenhouse gas intensive products traded internationally. Together, we can confront the challenge of climate change, ensure a strong global economy, and encourage the growth of clean energy worldwide.

Efectele cresterii temperaturii medii globale

2009-04-23T10:37:00.001-07:00

Cresterea temperaturii ameninta milioane de oameni cu aparitia foametei, malariilor, inundatiilor, furtunilor puternice si lipsa apei potabile.

Ar provoca un val de calduri mai ales prin statele slab-dezvoltate de pe continentele: Africa, Asia si America de Sud.

Numarul secetelor s-a dublat in ultimii 35 de ani.

S-ar topi calota glaciara

Ar creste numarul inundatiilor in unele zone si ar lipsi total apa potabila

30% din ghetarii Europei ar diparea

Foarte multe insule ar fi acaparate de catre ape

Sezonul de iarna ar deveni mai scurt, iar practicarea sporturilor de iarna foarte scumpe

Ar disparea paduri si specii (aproximativ 1000000), ceea ce ar afecta intreagaa Planeta si pe fiecare locuitor al ei, deoarece costurile alimentare ar creste exceptional.

Sfaturi pentru prevenirea Incalzirii Globale

2009-04-23T10:17:00.001-07:00

Informatiile si calculele au fost expuse de catre prezentatorii meteo din Europa, implicati in proiectul “Voi controlati schimbarile climatice”

reducerea cu 1 grad Celsius a temperaturii din casa reduce emisiile de CO2 cu 300 kg anual

nu lasati caldura sa iasa din casa pentru o perioada indelungata de timp (in timpul aerisirii lasati geamurile deschise pentru citeva minute doar)

incalzirea unei case pentru periaoda rece (6 luni) cu o temperatura exterioara de 10 grade Celsius arunca in atmosfera tone de CO2

izolarea termica a casei presupune 2 consecinte extrem de importante: economisirea banilor si reducerea emisiilor de carbon

nu amplasati frigiderul si congelatorul linga cuptor _ temperatura medie atinge 30 –35 grade Celsius, iar emisiile de CO2 ating 120 si 320 kg respectiv

stingeti luminile daca nu aveti nevoie de ele

becurile economice (becurile fluorescente) presupun o economie de aproximativ 60 de euro anual pentru fiecare bec in casa

evitati picurarea apei in robinete

opriti robinetul cind va periati pe dinti

scoateti aparatele electrice din priza cind nu le folositi

Sper ca intreprinzind aceste simple masuri vom reusi sa facem viata noastra si a celor din jur mai buna

Pe data de 21 martie 2009 în cadrul Liceul Academiei de Ştiinţe va avea loc dezbaterea publica în cadrul proiectului internaţional lansat de către ONU cu tema:

“Statele mari ar trebui sa fie responsabile de stoparea procesului de incalzire globala”

Echipa care sustine aceast fapt va trebui sa demonstreze ca implicarea statelor inalt-dezvoltate ar trebui sa se implice foarte activ si sa fie resposabile si perfect constiente de faptul ca ei trebuie sa stopeze procesul incalzirii globale. Afirmatorii vor aduce argumente in vederea faptului ca statele mari, cu o industrie bine-dezvoltata au fost si cei care au provocat incalzirea globala prin actiunile din trecut.

Negatorii vor avea sarcina de a-si sustine punctul de vedere ca prolema incalzirii globale este una prea importanta si prea responsabila pentru a o incredinta doar citorva state. Celelalte tari nu ar trebui sa lase de o parte problema data, ea fiind una care ne afecteaza pe toti si pe fiecare in parte. Din aceasta cauza proiectele de reducere a consumului de hidrocarburi trebuie sa se implementeze peste tot si noi trebuie sa globalizăm actiunile, poate nesemnificative, dar care intr-un numar mare vor putea schimba lumea. In solutionarea problemei are importanta anume numarul mare si cantiatea. Astfel daca se vor realiza actiuni din partea tuturor problema va fi solutionata!

Noi, elevii de la Liceul Academiei de Stiinte ne vom stradui in urmatoarele luni sa intreprindem mai multe actiuni pentru a populariza ideea incalzirii globale. Noi vom incerca prin mai multe metode sa ajutama oamenii sa inteleaga imporanta problemii incalzirii globale si cum sa ajutam fiecare in solutionarea acesteia.

Rezultatele acestei dezbateri captivante vor fi mentionate in urmatorul articol.

De de Germania si nu Moldova?

2009-03-12T11:46:00.001-07:00

După cum cunoaştem deja, încălzirea globală este cauzată de mai mulţi factori, precum distrugerea habitatelor, poluarea excesiva a biosferei, hidrosferei, litosferei şi atmosferei. Poluarea atmosferei presupune şi distrugerea stratului de ozon prin internediul gazelor de seră.

Este bine-cunoscut faptul că poluarea este direct-dependentă de nivelul dezvoltării economice a ţării, adică de consumul de combustibili fosili şi diverse hidrocarburi, în urma arderii cărora în aer se emana o cantitate impunătoare de bioxid de carbon, pe care atmosfera nu-l poate controla în mod natural.

Chiar dacă am arde foarte mult cărbune, poluarea mediului şi distrugerea stării ecologice, în final finală este determinată de către mai mulţi factori, şi anume capacitatea înlocuirii CO2-ului cu oxigenul, asigurat pe planetă în mare parte de către vegetaţie în urma procesului de fotosinteză.În trecut, cînd a început dezvoltarea vertiginoasă a economiei şi deverselor ramuri ale ei, baza acestei dezvoltări a constituit motorul cu ardere internă, şi anume petrolul şi alţi combustibili fosili. Atunci cantitatea de CO2 a crescut cu mult şi vegetaţia nu mai “accepta” o asemenea cantitate de CO2 pentru a o prelucra.

Evident că această invenţie a fost preluată şi popularizată în ţările cu ecnomia dezvoltată. Aceste ţări sunt Germania, Japonia, Marea Britanie, SUA, Rusia. Anume ţările mari au constituit factorul principal al poluării, deoarece nu s-a planificat utilizarea deşeurilor produse de către marile descoperiri, precum sunt îngrăţămîntul chimic, motorul cu ardere internă, energia nucleară etc. Poluarea se răsfrîngea asupra tuturor domeniilor: poluarea solului, emisiile de CO2 în atmosferă, defrişarea pădurilor, construcţia caselor, aruncarea deşeurilor în apele freatice sau direct în rîuri. Luate împreună ele au cauzat o stare foarte gravă a mediului ambiant.

În rezultat am obţinut că ecologia a suferit în cea mai mare parte din cauza ţărilor dezvoltate, care au utilizat neraţional acele descoperiri ştiinţifice împotriva naturii-mamă. Anume acestea ţări trebuie să implementeze măsuri radicale în lupta cu poluarea, iar ţările în curs de dezvoltare să nu repete greşelile trecutului!

De ce incalzirea globala?

2009-01-18T09:17:00.001-08:00

Noi locuim intr-o lume puternic industrializată si in prezent avem cele mai bune conditii de trai din toata istoria omenirii, avem acces la toate resursele pe care ni le-am putea dori si suntem cei mai influenti, adica suntem extrem de puternici si progresam in toate domeniile foarte rapid, evident in acele domeniii de care avem nevoie si care ne-ar face viata mia frumoasa. Apare atunci intrebarea, daca ne este asa de bine, de ce ne gindim la incalzirea globala, de ce sa ne limitam in ceea ce ne face viata o placere?

Raspunsul la aceasta intrebare se gaseste adinc in evolutia noastra spirituala. Fiind cei mai puternici, cel mai bine dezvoltati din punct de vedere spiritual si avem cea mai puternica gindire trebuie sa nu fim hapsini si ne gindim doar la noi.

Dupa cum a spus John F Kennedy “Cel ce priveste doar spre trecut sau viitor va pierde cu siguranta viitorul”. Astfel noi nu trebuie sa ne gindim doar la noi si situatia care este acum in jurul nostru. Am primit cadou de la viata o minunata masina de analiza si gindire, de aceea nu trebuie sa ratam sansa de a o pune in miscare. A gindi multilateral si a ne gindi la viitoarele generatii, la situatia intre specii inseamna a trai in echilibru cu totii, pentru ca numai asa noi vom ajunge sa ne folosim darul la maxim.

Geniul omului nu se ascunde in folosirea abilitatilor sale mintale pentru dinsul, un adevarat geniu universal este acela care se sacrifica pentru binele comun si pentru principii corecte, care ar aduce pe lume numai bine si ar face ca existenta noastra sa fie si mai frumoasa.

Incalzirea globala este un domeniu prin care omul gindeste multilateral, iar omenirea printr-un asemena mod a evoluat la cel ami inalt nivel, cind incepe sa se gindeasc nu numai la propriul bine, dar la binele comun.

Cerul nu mai este la fel de prielnic si binevoitor.

2008-12-28T10:15:00.002-08:00

Noi ne uitam spre cer dupa incurajare, dar in urma actiunilor noastre negative asupra mediului cerul ni se intoarce cu spatele, insuflind numai disperare. Ghetarii nu mai sunt la fel de mareti, distrugindu-se si aratind slabiciunea.

Viitorul planetei e in miinele noastre!

2008-12-28T10:15:00.001-08:00

Planeta are febra

2008-12-28T10:13:00.000-08:00

La fel ca si la om, planeta noastra nu se confrunta cu o boala serioasa in prezent si trebuie sa depundem cu totii efort pentru a o vindeca.

Refugierea

2008-12-28T10:11:00.000-08:00

Daca nu vom fi atenti la actiunile noastre riscam sa ne gistrugem planeta, iar de altfel va trebui sa ne cautam o alta casa in necuprinsul nostru Univers.

Distrugerea stratului de ozon determina topirea ghetarilor din munti.

Interview with minister of ecology of Moldova Voleta Ivanov

2008-12-28T09:50:00.000-08:00

Acest interviu a fost realizat cu doamna minstru al ecologiei si resurselor natural din Republica Moldova. Elevul Liceului Academiei de Stiinte din Moldova, Ciobanu Petru a intrebat despre actiunile pe care doreste sa le realizeze ministrerul ecologiei in urmatorii 10 ani.

Topirea ghetarilor

2008-12-28T09:32:00.000-08:00

Formarea glaciatiunilro la polii planetei se datoreaza in mare parte faptului ca razele solare cad sub un unghi mic si marea partea a radiatiei solare este reflectata inapoi in Univers. Astfel in Antarctida se mentine temperatura joasa, care determina prezenta continua a ghetarilor.

Cu toate acestea un alt factor, care determina prezenta ghetarilor este culoarea alba a zapezilor, care acopera al 6 lea continent. Culoarea alba respinge caldura solara , si asigura o temperatura joasa constatnta. Astfel se pastreaza echilibrul: acolo unde e rece se mentine rece, acolo unde e cald, caldura ramine constanta.

Umatorul fapt interesant, reiesit din teoria expusa mai sus este acela ca culoarea intunecata atrage radiatia solara, sau accepta caldura venita din exterior.

Suprapunind aceste 2 lucruri realizam urmatoarea concluzie. Planeta noastra este un obiect integru si regiunile in care este divizata geografic mereu interactioneaza intre ele. Daca spre exemplu Antarctida este asigurata in fata incalzirii prin culoarea alba si unghiul mic, ea este neputincioasa in fata caldurii excesive venite din interiorul planetei, spre exemplu curentii calzi dinspre Ecuator. Cunoastem de asemenea ca curentii de aer aduc la poli toate substantele poluante, care distrug ozonul deasupra Antarctidei si determina patrunderea razelor ultraviolete.
Daca von ataca cu atita insitenta planeta si glaciatiunile ele nu vor rezista si vor disparea. Intr-un moment crucial se poate intimpla un lucru extraordinar. Putem obtine in rezultat un efect invers. Cantiatea de caldura mare venita dinspre Ecuator farimiteaza continetul, razele ultraviolete ataca de sus. Adica suprafata alba care respinge radiatia este inlocuita prin apa intunecata a Oceanului, care absoarbe caldura provenita de la stea. Si se formeaza efectul mentionat mai sus: unde e cald, se pastreaza caldura.

Drept consecinta oamenii vor fi nevoiti sa se mute cu traiul in munti.

Topirea ghetarilor de pe TERRA

Conform unor date aproximative, nivelul marii in oceanul planetar s-ar putea ridica cu 10 de metri, daca se vor topi ghetarii din Groenlanda si cu aproximativ 30 de metri, daca va disparea glaciatiunea Antarctida.

Istoria climei si necazul planetei

2008-12-07T05:25:00.000-08:00

Clima pe Terra a suportat multe schimbari pe parcursul timpului.

Etapa precambriana - clima rece si formarea calotelor glaciare

Etapa eopaleozoica - incalzirea climei

Etapa neopaleozoica - racirea climei

Etapa mezozoica - incalzirea climei

Etapa cainozoica - racirea climei

Prezent - incalzirea climei

Astfel are loc perindarea perioadelor de incalzire si racire a climei. Toata istoria climatica a planetei era determinata de factori invariabili precum eruptiile vulcanice, perioadele de activitate solara etc.

Pentru prima data in istorie noi urmarim cum OMUL, cu propriile puteri schimba spre rau clima planetei, deoarece distruge foarte repede lucruri care erau stabile timp de milioane de ani. Topirea accelerata a ghetarilor, cresterea neasteptata a temperaturilor pe intreg globul pamintesc, distrugerea speciilor de animale si plante, ocuparea teritoriului de la oceane si mari, aruncarea in atmosfera a resurselor de carbon din interiorul planetei, preoducere plasticului in cantitati enorme. Toate aceste actiuni a factorului antropic a determinat distrugerea echilibrului natural. NOI suntem martorii acestor terorizari a planetei noastre si trebuie sa luptam cu acest viciu.

Exista in prezent pericolul disparitiei Antarctidei si Groenlandei - calotele glaciare, care adapostesc aproximativ 70 de procente din resursele acvatice a planetei. Daca va avea loc topirea acestora specia umana se va transforma din una dominanta in una dintre cele mai vulnerabile, deoarece inundatiile aduc dupa sine multe necazuri. Pe linga faptul ca se vor acoperi de apa extrem de mult teritoriu din uscat, exista riscul aparitiei bolillor, care vor ucide si mai multi oameni. Din cauza inaccesului la apa potabila vor muri si mai multi oameni. De asemenea va exista un pericol foarte acut pentru agricultura si lipsa alimentelor, lipsa echilibrului natural (producerea oxigenului si schimbul de substante in ecolsisteme). Practic se vor deregla toate instrumentele prezentului, care mentin societatea noastra la un nivel inalt.

In asemenea conditii toti vor uita de petrol, de motorina, de masini si avioane, industria distractiilor, care este un consumator mare de energie in toata lumea. Oare nu ar fi mai bine daca oprim procesul din prezent, fara sa asteptam consecintele?, deoarece exista foarte multe posibilitati de reducere a consumului de conbustibil in domeniul transportului. Daca am unifica teritoriul aerian al statelor avioanele nu ar trebui sa inconjoare mult si am reduce si timpul de zbor. Daca am incepe implementarea tehnologiilor ecologice in transportul public si individual (spre exemplu motocicleta sau masina electrica) s-ar reduce cu mult poluarea centrelor urbane si s-ar micsora numarul accidenteor rutiere. Daca am calatori la distante mari in cadrul unui stat cu trenurile Maglev calatoriile ar dura mai putin si tehnologiile s-ar dezvolta mai intens, devenind si mai ecologice.

Practic solutiile existe, iar fiecare dintre noi trebuie sa inceapa schimbarea de la sine, facind tot posibilul ca viitorul utopic sa apar cit mai repede.

Dezbaterea publica la Liceul Academiei de Stiinte

2008-12-04T14:12:00.000-08:00

La Liceul Academiei de Stiinte a Moldovei a fost organizata o dezbatere publica cu motiunea "Lumea ar trebui sa elaboreze planuri de stopare a precesului de incalzire globala". La dezbaterea organizata in cadrul liceului au asistat invitati din diverse structuri, astfel la dezbatere au fost prezenti:

Domnul Gheorghe Duca - presendintele Academiei de Stiinte a Modovei
Doamna Perciuleac Ludmila - coordonator principal al proiectului GLOBE in Republica Moldova si director al Liceului ASM
Doamna Iulia Moldovean - presedintele Ligii Nationale de Dezbateri
Domnul Ion Bahnarel - coordonator stiintific la Centrul de Medicina Preventiva

In cadrul acestei manifestari elevii liceului au discutat asupra subiectului dat, analizind aspectele pozitive si cele negative ale implementarii unor proiecte de reduce emisiile gazelor toxice. Afrimatorii au afirmat ca exista o importanta acuta pentru implementarea unor proiecte radicale de imbunatatire a starii ecologice si salvarea plaentei de o eventuala era glaciara. Negatorii insa au afirmat ca nu exista o asemenea necesitate, deorece se suprapun si alte fenomene naturale, pe care omul nu le poate controla si care au o influenta mai mare asupra climei intregii planete.

Dezbaterea a avut un caracter destul de tolerant, ambele echipe avind argumente puternice in apararea ideii ce corespundea cazului lor. Acest fapt a fost recunoscut si de arbitri. De asemenea invitatii au recunoscut importanta majora a subiectului abordat atit pentru intreaga planeta, cit si pentru Moldova.

Concluzia dezbaterii a fost importanta fiecaruia dintre noi in stoparea emisiilor de carbon si corectarea greselilor trecutului, care le revin viitoarei generatii de savanti, oameni politici si cei care vor putea aduce cu ei SCHIMBAREA.

Public debate at the Lyceum of the Moldavian Academy of Science

Video prezinta dezbaterea publica care a avut loc la Liceul Academiei de Stiinte a Moldovei, in prezenta mai multor invitati speciali, avind ca motiune tema propusa de proiectul international"The People Speak", lansat de ONU - "The world should adopt a plan to significantly combat climate change ". Elevii care au participal au format 2 echipe: negatoare si afirmatoare, analizind necesitatea intreprinderii masurilor de prevenire a incalzirii globale.

Problemele ecologice globale

2008-12-04T10:28:00.001-08:00

Ce este incalzirea globala si cum putem lupta cu ea?

Incalzirea globala este efectul provocat in mare parte de industrializarea intensa precedata de emisiile de gaze cu efect de sera. Efectul de sera presupune absorbtia energiei solare si imposibilitatea eliminarii ei din atmosfera, astfel ea raminind pe Terra si incalzind temperatura pe planeta. Unele grave consecinte ale acestui fapt pot deveni:

Topirea totala a ghetarilor din Groenlanda si Antarctida
Transformarea padurii tropicale Amazon in pustiu
Ridicarea nivelului marii cu 30 de metri

Lumea lupta astazi cu incalzirea globala prin toate instrumentele de care dispun. Unul din principalele instrumente este informarea populatiei cu privire la acest fenomen si intreprinderea anumitor actiuni ce vor imbunatati starea ecologica generala.

In primul rind fiecare dintre locuitorii planetei noastre trebuie sa se gindeasca la propriile economii privind utilizarea energiei electrice si termice, cum am putea sa micsoram consumul de energie sau cum ar putea el deveni mai mic? Daca vom face acest lucru rezultatele vor fi benefice pentru mediul ambiant, dar si pentru propriul buzunar.

Unele masuri care pot fi realizate de catre fiecare sunt:

1 Sa avem grija sa stingem lumina dupa ce iesim din casa
2 Sa utilizam becuri mai eficiente (se cunoaste ca un bec traditional elimina doar 2 procente de lumina din totalul energiei electrice consumate, restul fiind eliminata in atmosfera sub forma de caldura)
3 Sa nu irosim apa in timpul dusului de dimineata si in urma altor actiuni cotidiene
4 Sadirea si ingrijirea unui copac intr-un loc, unde acesta lipsea.

Haideti sa fim mai atenti asupra actiunilor noastre, si planeta ne va fi recunoscatoare pentru aceasta
