what can we do about (global warming )

Ficheiro:2000 Year Temperature Comparison.png

global warming is  the average temperature increase of air and oceans.
  Global dimming, a result of increasedconcentrations of atmospheric aerosols that block part of the solar radiation before it reaches the Earth's surface, partially maskedthe effects of warming induced by greenhousegases.
An increase in global temperatures may in turn cause other changes, including increased sea level, changes in rainfall patterns resulting infloods and droughts.
The global warming is caused by aerosols and burned like this pictures .

Every day we followed on television, in newspapers and magazines disasters andclimate changes that are occurring rapidly in theglobal climate. Never seen such rapid changeand with devastating effects as has occurred in recent years.
Climate researchers say that global warming is occurring due to the increase of greenhouse gas emissionsmainly derived from burning fossil fuels (gasoline, diesel, etc.in the atmosphere. These gases (ozone, carbon dioxide, methane, nitrous oxide and carbon monoxide) form a layer of pollutants difficultdispersion, causing the known greenhouse effect. This phenomenon occurs because thesegases absorb much of the infrared radiationemitted by the Earth, making the dispersion of heat
