I read a report some years back that it will only take 100 years fo the 2 mile high Ice Cap to reform. Might be outdated info though.
I think you and I must have read the same report!
Here’s a guy who if right, then we really really need global warming and lots of it.
The thing is there is more physical evidence (not computer simulation!) to support this guy’s case, then there is for catastrophic warming.
The bottom line is there will be a major cooling (glaciation!) again simply because past history says so it’s just a matter of when! The last major glaciation was not the last ever major glaciation! That would only be if the case if something extraordinary happened regarding earth and all the interacting (nonlinear!) geophysical systems that make it up.
