Did some research on ice ages and it sounds like man made climate change will ensure we do not see another ice age! Too me that sounds like a good thing! But then I read into how sun and volcano activity could alter everything again no matter what we about our own emissions. This is all out of our hands and not worth fretting about is what I settled on. We will all be able to survive in a warm climate but an ice age could kill most of us.....
Toss "precession" into your next search for climate change. That also provides a lot of interesting stuff to read.
