What would happen if two people out in space a few meters apart, abandoned by their spacecraft, decided to wait until gravity pulled them together? My initial thought was that …
A Reasonable Perspective on Global Warming

I was pointed to this talk by Dr Judith Curry’s website, which also seems to be a breath of fresh air on this whole topic. It seems serious and scientific. It doesn’t resort to the hysteria of Al Gore or of Sarah Palin.
I’m looking forward to following these groups more closely in the future.
