Living in the asphalt jungle that you do, Scaeagles, I'm really surprised that you think this is not man made, or at least being hastened and made worse by our contributions. The periodic spike or lowering of temps in times past has nearly always had an explanation- volcanic eruptions like Krakatoa, or meteor collisions that sent clouds of dust into the atmosphere for decades. I know the temps in Phoenix are much worse than they used to be, and the reason is the astounding amount of asphalt and lack of greenery. The air in many major cities is toxic, and untold rivers, coastal shorelines and bodies of water have been poisoned by heavy metals, crude oil, etc. We are ruining our environment, and it stands to reason that the atmosphere will follow. You can point to the "hundreds' of scientists (never mind who they may be working for) but thousands more refute their finds. I only have to fly into LA to be reminded of what we are doing to the very air we breathe, and I am thankful there are still a few places left that have clear air and clean water.
