Human activities are the main cause of global warming？

Does human activity to global warming to accelerate, has become of our times, one of the biggest scientific controversies. If this is true, the greater question is what global warming will lead to the consequences of the human ability to stop it? Governments, policy-makers spent two weeks in Copenhagen climate summit debate these issues. But unfortunately, they ultimately failed to reach a reduction of greenhouse gas emissions and stop global warming, international agreements, and those arguments are behind scientific uncertainty.

Mainstream climate scientists insist that human activity is to promote global warming, the biggest factor. And some global warming skeptics believe that it is still not sufficient evidence to prove this point. Square root of both arguments lies in science. There is no doubt that, since the industrial revolution, the Earth's atmosphere of carbon dioxide gas concentrations are increasing, which the majority is the result of burning fossil fuels. In addition, the global average temperature is also rising. But now the two sides of the central theme of debate is whether global warming caused by carbon dioxide, a direct consequence of an increase, rather than a result of the Earth's own climate regulation.

The United Nations Intergovernmental Panel on Climate Change fourth climate assessment shows that global warming has been unquestionable, air and ocean temperatures have risen sharply in the conclusive evidence of melting glaciers and snow-capped mountains are melting, sea levels are rising. While the global average temperature rise is proportional to human greenhouse gas emissions. But this is not absolute, global warming may be the Earth's climate naturally regulate their own results.

British climate science professor at University of East Anglia, said Michael Hume, in support of human activity to change the global climate system, the scientific evidence is now overwhelming advantage. But the understanding of climate warming and climate change occurs is also very important for various reasons. We have to admit, because human beings have different political, international, organization, religious and cultural differences, they look at the way the world is different.
