1 Global Warming

2 what is global warming ? Global warming is the increase in average temperature of the oceans and air near the earth's surface occurred since mid-twentieth century and should remain in the XXI century Global warming is the increase in average temperature of the oceans and air near the earth's surface occurred since mid-twentieth century and should remain in the XXI century Most of the temperature rise observed since the mid- twentieth century was caused by increasing concentrations of greenhouse gases as a result of human activities like burning fossil fuels and deforestation.

3 Continue The global dimming of the ozone layer, a result of increased concentrations of atmospheric aerosols that block part of the solar radiation before it reaches Earth's surface, partially masked the effects of warming induced by greenhouse. The global dimming of the ozone layer, a result of increased concentrations of atmospheric aerosols that block part of the solar radiation before it reaches Earth's surface, partially masked the effects of warming induced by greenhouse. The increase in global temperatures may in turn cause other changes, including increased sea levels, changes in precipitation patterns resulting in floods and droughts.

5 The consequences of global warming Increased sea levels: with increasing temperature in the world, is ongoing melting of polar ice caps. By increasing the water level of the oceans, may occur in the future, the submersion of many coastal cities; Increased sea levels: with increasing temperature in the world, is ongoing melting of polar ice caps. By increasing the water level of the oceans, may occur in the future, the submersion of many coastal cities; Increase of hurricanes, typhoons and cyclones: the increase in temperature causes more evaporation occurs from the ocean waters, leveraging these types of weather disasters Increase of hurricanes, typhoons and cyclones: the increase in temperature causes more evaporation occurs from the ocean waters, leveraging these types of weather disasters

7 Advice for the warmers The car is not the means of transport more environmentally correct. Use it sparingly. Come over public transport. The car is not the means of transport more environmentally correct. Use it sparingly. Come over public transport. replace their incandescent bulbs with fluorescent replace their incandescent bulbs with fluorescent clean or replace the filters of your air conditioner clean or replace the filters of your air conditioner use less hot water use less hot water

8 The End help save the planet all together less pollution and better consensus.
