The subject of global warming often gives rise to heated debate, especially in political circles. Scientists have come out in support of both sides of the issue and each side latches on to whatever theory supports their particular stance.
In the extreme cold temperatures of the winter of 2010, there were many jokes about the absence of global warming and supporters were forced to find theories to defend its existence. Die-hard global warming theorists said that dramatic temperature swings were actually the result of global warming. However, those who dispute global warming have been pretty quiet these last few weeks. In light of all the record high temperatures set, it's a difficult one to argue right now.
What do you think? Does this heat wave prove the global warming theory once and for all, or is it just part of natural climate changes that vary from season to season and decade to decade?
