Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases
Global Warming
The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases.

Causes of Global Warming
Greenhouse gases are released into the atmosphere in many ways, including through the burning of fossil fuels (such as coal and petroleum) and by deforestation. As some environments warm (e.g. the Arctic tundra) they also release carbon that may have been stored for thousands of years.

Because greenhouse gas emissions are tied very closely to our energy consumption, using less fossil fuel based energy puts fewer greenhouse gases into the atmosphere.
This will help slow global warming.
Reduce our consumption of fossil fuels

50% of electricity in the United States is produced from coal.

How many of you use handkerchiefs instead of tissues and use cloth towels instead of paper towels?
Paper comes from trees. the more we use, the more trees that are cut down 2 pts
Save Trees
To save the Earth we all gotta try, or else in the future we’re all gonna fry!
Global Warming: We have a solution, Stop Pollution
Let the earth Icy, Not Spicy
Global warming everywhere, no solution anywhere
