Global warming is actually happening in our world today is hotter than ever in the past two thousand years. If this condition happens next. When the end of this decade Global temperatures tend to be higher than ever in the past two million years. Although the 20th century ended, the weather may not be hot in the history of the world. But that never happened, it was the heat that occurs worldwide. And can not be explained by natural mechanisms that explain the warming in the past. Scientific information broadly agreed that mankind has contributed greatly to the cause of this change. And the choice we made today will determine the climate in the future , how do we make climate change for more than one decade ago, people rely on fossil fuels like oil, coal and natural gas to meet its energy needs. Fuel carbon dioxide emissions, which cause global warming, into the atmosphere. Other greenhouse gases To create more impact As well as cause Including deforestation enormous "present. Understanding the science of global warming is clear enough to be a reason for countries. To act immediately, " - the communiqué of the National Academy of Sciences, 11 of which were presented to world leaders. (Read full text) The fact that we know , although there are uncertainties. In particular, the difference in time and scope of regional warming. But a mutual recognition of scientific facts, major following • gases such as carbon dioxide in the atmosphere that cause the "greenhouse effect" which store heat out and keeping the world warm enough. to nourish life As we know well •. The burning of fossil fuels (coal, oil, etc.), release carbon dioxide into the atmosphere even more. Although carbon is not a site to build the most affected. It's a gas man is causing the most. Since being released large quantities •. The current concentration of carbon dioxide in the atmosphere is at the highest level in 150,000 years • We expect that the 1990s was the warmest decade on record and 1998 (2541) was the warmest year also. also accepted widely shared in the following •. Heat rises to a certain level that is approximately 1.3 ° C (2.3 ° F) compared to pre-industrial levels. May is inevitable considering the emissions to date. Restrictions apply heat to below 2 degrees Celsius (3.6 ° F), it is necessary to prevent the effects of global warming •. If you can not control the emission of greenhouse gases. Global warming in the next 100 years will occur more quickly than ever since the birth of human civilization •. Is a high possibility that the response mechanisms in the climate will lead to immediate climate change and can not be returned intact. No one knows that global warming will have a more serious one, it will trigger. "Doomsday scenario" link.
