The Earth stays warm and comfortable in the coldness of space by using a natural process called the greenhouse effect. When the Sun's radiation reaches our atmosphere,some reflects back into space and some is absorbed by the Earth and causes the surface of the Earth to heat up. The heat from the Earth is radiated outward and absorbed by the "greenhouse gases" in the atmosphere which prevents heat from dissapearing into space which keeps the Earth warm enough to sustain life. Global warming can be caused by humans realeasing additional greenhouse gases into the atmosphere which includes carbon dioxide, methane, and nitrous oxide.

=Is Global Warming Real Reflection= The best way to keep track of the increasing temperatures around the world is to look at the thermometer records kept over the last century and a half. We can also see what the weather was like, we can look at the trees rings over the time they were alive and look at the lakes and oceans by observing the sediments that are on the ocean and lake floors.

I personaly think, in my own opinion, that global warming is not real. I realize that humans do pollute and cause landfills and use our fossil fuels a lot. I think that in general humans do not do anything wrong to cause global warming.
