I could not agree more Dan. Imo most people, even scientists, might not be 
able to take the whole truth. Our species is very good at extremely over 
simplified dichotomies. Most are by now convinced climate change is taking 
place. Ice is melting everywhere. But is that our fault? Or is the sun 
indeed putting out more enery?
Worst case scenario is if both are right at the same time. There were times 
on earth that CO2 levels were higher than they are now and life was 
abundant. So why panic if we should move towards the same levels of green 
house gas as in the Carboniferous?
If at the same time the sun puts out more energy we may very well all get 
fried is why.

So many factors are still uncertain, ice is melting and sea water levels 
should be rising. Instead we seem to have had a sea level drop of 10 mm in 
just a few years according to some research and this scares me seriously.
If that research is correct then where did all that water (many, many cubic 
miles of water) go?

It is almost a certainty that if both humans and the sun are responsible 
that we may loose all water on Earth eventually. Just maybe this is what is 
happening already. And maybe this is the reason that serious people have the 
luxury to still be discussing temperature rises in single digits. Water 
escaping the atmosphere would have a serious cooling effect for a while.
Nothing new here, at the very moment the Turks attacking Byzantium were 
breaking down the gates of that city the theologians inside where discussing 
with vigour the question of how many angels could dance at the one time on 
the point of a needle.

In a real worst case scenario we may be getting temperature rises of a few 
hundred degrees.
