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 usesthe term anthropogenic climate change.
Climate change
Greenhouse EffectThe 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.
Climate change nowFossil fuels and global warming:
Burning oil, coal and natural gas has caused increase in CO2 in the atmosphere is 1.4 ppm per year and produces an increase in temperature. It is estimated that the man that measures the temperature at about 150 years has increased 0.5 ° C .
Plan for the future:In the Cretaceous, without human intervention, the CO2 was higher than now and the earth was 8 ° C warmer.AgricultureIt is expected that global warming will have a significant impact affecting agriculture .... These conditions determine the carrying capacity of the biosphere to produce enough food for all humans and pets.

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. In India, although it is business as usual so far for CSR, it is likely that the practice will become more tightly focused. Meanwhile, in Africa, declining resources point to the need to focus on developing self-sustainable CSOs. In the Arab region, however, massive commitments for the reconstruction of Gaza are defying all the trends.
