I truly think that there is climate change! That being said, we have only kept track of the weather records for about 150 yrs. That is only a drop in the bucket of time, they have found seashells in the Rocky Mountains and all sorts of other thing that they don't have a clue as to how they got there. We may be in a cooling cycle right now...I Don't know and if the man above wants it hotter, then will have it or he can make ice! It's been happening since before man was walking this Earth and it will be so after we are gone. We shouldn't pollute or air or water for humanity, but what happens.....happens. Not a lot we can do about it!
