global warming

The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect. Visible, shortwave light comes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases composed largely of water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Infrared radiations reflect off the planet's surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward, keeping the planet at an average temperature sutable to life, about 60°F (16°C).Among factors that may be contributing to global warming are the burning of coal and petroleum products (sources of carbon dioxide, methane, nitrous oxide, ozone); deforestation, which increases the amount of carbon dioxide in the atmosphere; methane gas released in animal waste; and increased cattle production, which contributes to deforestation, methane production, and use of fossil fuels. Five international agreements were signed amid tensions between the industrialized countries of the North and the poorer developing states of the South, who were reluctant to accept environmental restrictions without increased Northern economic aid. Follow-up meetings were held in 1997 at the UN General Assembly in New York and in 2002 in Johannesburg.A 2007 report by the Intergovernmental Panel on Climate Change, based on a three-year study, termed global warming "unequivocal" and said that most of the change was most likely due to human activities. A UN Conference on Climate Change, held in Kyoto, Japan, in 1997 resulted in an international agreement to fight global warming, which called for reductions in emissions of greenhouse gases by industrialized nations. Not all industrial countries, however, immediately signed or ratified the accord.


I think people seriously should start to think about global warming not for theirselves for their next genereations because they will be concerned.We must talk or think about the solutions,real solutions for the global warming not the causes because we all know the causes.I`m not saying that we can definitly stop the global warming but we can delay it by using our needs like electricity,oil,more economicly
