In the desert in the middle of summer when its 110, Algore will be out saying "see, I told you global warming exisited" oh brother!
You ignorant shit most climatologist agree that it will only be about 1 degree change on the global average. The problem isn`t in temperature it`s in world wind and water currents getting severly fucked up. The artic is melting, dropping cold water into the grand banks, making the eastern seaboard colder in winter.
This 1 degree change will mean way more droughts, floods, heat waves and cold fronts. Inconsistant and unpredictable whether will be the norm. Which means food production is fucked, as the bulk of the worlds food supplies come from only 2 or 3 seperate places.
