Global Warming Could Mean No More Pets

[rabernet]

well correct me if I am wrong but hasn't it been proven that the earth goes through a natural warm and cooling progression and this has been happening forever??

Yes. And it's also been proven that other planets in our solar system are experiencing the same overall temp increases as we are, at the same rate. Those planets really need to clean up their act!

Or perhaps, it's just normal solar shifts causing the global warming?

Remember in the 70's and 80's that we were being warned of global cooling?
