Thesis: Due to increased levels of CO2, it is believed by many scientists civilization could come to an end sooner than expected.

     In the last 10,000 years our climate has raised 1.5 degrees above average. That may not seem like a lot, but it has been enough to start melting away the arctic. David Ray Griffin quotes Lonnie Thompson, who received the U.S. National Medal of Science in 2010, said that virtually all climatologists "are now convinced that global warming poses a clear and present danger to civilization."

     This has lead to an idea that if our climate can stay below a raise of 3.6 degrees, then civilization just might make it. Other scientists are lead to believe that if this 1.5 degree climate raise has started melting away the arctic, what will happen once temperatures get 3.6 degrees above average? They aren't yet sure because there is no evidence humanity could survive temperatures that high.

     The leading cause for this possible disaster is all of the burning of coal, oil and other gasses. So, how do we keep our climate from exceeding inhabitable temperatures? It would take the world to start replacing dirty energy with clean energy ASAP.
