I can't believe a lot of you don't think humans are a big part of the problem. The temperature and rainfall records were broken again and again the last few years. Of course the climate changed big time in the hisory of the earth but not nearly with the enormous speed that it is doing now. We are already halfway through the winter were I live and the temperature hasn't even been below zero yet which is very unusuall. In my garden there were flowers growing last month that only grow in april and may normally.
We push carbon dioxide into the air every year that took the earth millions of years to absorb. Ofcourse we influence the climate, a lot.
