An enhanced greenhouse effect is expected to cause cooling in higher parts of the atmosphere because the increased "blanketing" effect in the lower atmosphere holds in more heat. Cooling of the lower stratosphere (about 30-35,000ft.) since 1979 is shown by both satellite Microwave Sounding Unit and radiosonde data, but is larger in the radiosonde data.
There has been a general, but not global, tendency toward reduced diurnal temperature range (the difference between high and low daily temperatures) over about 50% of the global land mass since the middle of the 20th century. Cloud cover has increased in many of the areas with reduced diurnal temperature range.
Relatively cool surface and tropospheric temperatures, and a relatively warmer lower stratosphere, were observed in 1992 and 1993, following the 1991 eruption of Mt. Pinatubo. The warming reappeared in 1994. A dramatic global warming, at least partly associated with the record El Nino, took place in 1998. This warming episode is reflected from the surface to the top of the troposphere. Indirect indicators of warming such as borehole temperatures, snow cover, and glacier recession data, are in substantial agreement with the more direct indicators of recent warmth.
Arctic sea ice has decreased since 1973, when satellite measurements began but Antarctic sea ice may have increased slightly.
Can we change the climate
It may seem hard to believe that people can actually change the Earth’s climate. But scientists think that the things people do that send greenhouse gases into the air are making our planet warmer.
Once, all climate changes occurred naturally. However, during the Industrial Revolution, we began altering our climate and environment through agricultural and industrial practices. The Industrial Revolution was a time when people began using machines to make life easier. It started more than 200 years ago and changed the way humans live. Before the Industrial Revolution, human activity released very few gases into the atmosphere, but now through population growth, fossil fuel burning, and deforestation, we are affecting the mixture of gases in the atmosphere.
Since the Industrial Revolution, the need for energy to run machines has steadily increased. Some energy, like the energy you need to do your homework, comes from the food you eat. But other energy, like the energy that makes cars run and much of the energy used to light and heat our homes, comes from fuels like coal and oil – fossil fuels. Burning these fuels releases greenhouse gases.
Environmental protection in Ukraine
In the 20th century, the rapid growth of science and technology resulted in an increasing negative effect on the biosphere of the Earth. Huge industrial enterprises pollute the air we breathe? The water we drink and the land, which gives us bread, vegetables, and fruit. Their discharge of dust and gas into the atmosphere returns to the Earth in the form of acid rains. It also destroys the ozone layer of the Earth and causes ‘’ greenhouse effect‘’. It effects forests, rivers, crops and people’s health. This leads to the reduction of the life-span of man. People die younger because of cancer, AIDS and other diseases which are directly connected with the polluted environment they live in. Many species of animals and birds face extinction due to the pollution of the biosphere.
The world’s oceans are in danger too. They are filled with poisonous industrial and nuclear waste, chemical fertilizers and pesticides. The Aral Sea in Russia is already dead, the Mediterranean and the North Sea are slowly dying.
The worst situation with air pollution is in big overpopulated cities. In Cairo and Mexico City, for example, breathing is equivalent to smoking 2 packs of cigarettes a day. The big industrial cities in Ukraine like Zaporizhiya, Donetsk, Kharkiv and some others have the same situation.
Another threat for the environment are nuclear power stations like Chernobyl. In April 1986 that nuclear power plant just north-west of Kyiv suffered the worst nuclear accident in history: dozens died immediately, tens of thousands were evacuated, while the long-term effects to human life are difficult to calculate. A large part of Ukraine, Russia and Byelorussia was polluted by radioactive substances. Great damage was done to their economy, nature and people’s health. The problem of Chernobyl has not been solved yet because of the economic difficulties that Ukraine is having now. The power plant was closed on December 15, 2000.
Nowadays people of Ukraine, like most people in developed countries, realize that without solving environmental problems, the life of the future generations will be in real danger. Many people join the Great Party of Ukraine to unite their efforts to save the planet where we live, to make our world healthier and more beautiful.
Greenpeace
Greenpeace is an international environmental organization founded in Vancouver, British Columbia, Canada in 1971. It is best known for its campaigns against whaling. In later years, the focus of the organization turned to other environmental issues, including bottom trawling, global warming, ancient forest destruction, nuclear power, and genetic engineering. Greenpeace has national and regional offices in 42 countries worldwide, all of which are affiliated to the Amsterdam-based Greenpeace International. The global organization receives its income through the individual contributions of an estimated 2.8 million financial supporters, as well as from grants from charitable foundations, but does not accept funding from governments or corporations.
Mission statement
Greenpeace's official mission statement describes the organization and its aims thus:
Greenpeace is an independent, campaigning organization which uses peaceful direct action and creative communication to expose global environmental problems, and to force solutions for a green and peaceful future. Greenpeace's goal is to ensure the ability of the earth to nurture life in all its diversity.
Structure
Greenpeace is a global environmental organization, consisting of Greenpeace International (Stichting Greenpeace Council) in Amsterdam, and 27 national and regional offices around the world, providing a presence in 41 countries. These national and regional offices are largely autonomous in carrying out jointly agreed global campaign strategies within the local context they operate in, and in seeking the necessary financial support from donors to fund this work. National and regional offices support a network of volunteer-run local groups. Local groups participate in campaigns in their area, and mobilise for larger protests and activities elsewhere. Millions of supporters who are not organized into local groups support Greenpeace by making financial donations and participating in campaigns as citizens and consumers.
National and regional offices
Greenpeace is present in the following countries and regions, as of March 2007:Argentina, Australia-Pacific region (Australia, Fiji, Papua New-Guinea, Solomon Islands), Belgium, Brazil, Canada, Chile, China, Czech Republic, France, Germany, Greenpeace Nordic (Denmark, Finland, Norway, Sweden), Greece, Greenpeace Central and Eastern Europe (Austria, Hungary, Slovak Republic, Poland, Romania, Bulgaria, Slovenia, Serbia, Montenegro and Bosnia), India, Italy, Japan, Luxembourg, Greenpeace Mediterranean (Israel, Cyprus, Lebanon, Malta, Tunisia, Turkey), Mexico, the Netherlands, Greenpeace Aotearoa New Zealand (New Zealand), Russia, South-East Asia (Philippines, Indonesia, Thailand), Spain, Switzerland, United Kingdom, and the United States.
Friend of Earth (FoE)
Friends of the Earth is the U.S. voice of an influential, international network of grassroots groups in 70 countries. Founded in San Francisco in 1969 by David Brower, Friends of the Earth has for decades been at the forefront of high-profile efforts to create a more healthy, just world. There members were the founders of what is now the world's largest federation of democratically elected environmental groups, Friends of the Earth International.
In March of 2005, Friends of the Earth finalized a merger with Bluewater Network. Bluewater is a dynamic organization with creative campaigns to combat global warming, air and water pollution and damage to public lands by thrill vehicles such as snowmobiles and jetskis. The merger has added to our capacity and enabled us to broaden the scope of our work in a number of areas.
Among there present efforts are successes that draw headlines nationwide and international and local efforts that make a difference in your backyard and those of people a world away.
FoE conducted lab tests that confirmed our suspicion that genetically engineered corn not approved for human consumption was in products on supermarket shelves across the nation.
They also exposed the fact that Enron received $2.5 billion in taxpayer loans funneled through international financial institutions.
In Indiana, they are working with local groups to fight the destructive new-terrain I-69 project. This 140-mile, $1.8 billion highway would demolish thousands of acres of farms and forests and bisect an Amish community.
Over the years, there efforts and those of our supporters mean FoE have been able to: stop over 150 bad dams and water projects worldwide; ban international whaling; oust infamous James Watt; press for landmark regulations of strip mining and oil tankers; reform the World Bank; and eliminate billions in taxpayer subsidies to corporate polluters.
