This change is produced very different time scales and especially climate parameters: temperature, precipitation, cloudiness, etc.. Are due to natural causes and, in recent centuries, so that man action on the environment. The term is often used vaguely appropriate, using as a synonym for global warming. UNFCCC (United Nations Framework Convention on Climate Change) uses the term climate change only to refer to human- causes. When called, produced by natural climate variability. In some cases, to refer to human-induced change also uses the term anthropogenic climate change. Climate change
Greenhouse Effect The pollution caused by burning fossil fuels is damaging our environment. Emissions from cars, homes or industries are rich in a gas called carbon dioxide. This gas reaches the atmosphere and reflected back to the earth's surface, solar energy. This process is called the greenhouse effect and causes an increase in temperature on our planet.

The effects of the financial crisis are just beginning to be felt, showing the impact the crisis is having on philanthropy and civil society. Brazil and Russia detected the first signs of reduction of corporate giving.
