Re: Mystery of Mass Extinctions Is No Longer Murky

[David Marjanovic <david.marjanovic@gmx.at>]

I don't understand why some people insist that a mass extinction cannot 
possibly have a single cause. Sure everything tends to turn out to be more 
complicated than we thought at first, but why start with the maximally 
munificent hypothesis?

If by "runaway" you actually mean "runaway", as on Venus, then it isn't. 
There is no chance that it could get so hot it doesn't rain anymore.

But a sea-level rise of a single meter, let alone three, is bad enough. 
We're talking about hundreds of millions of people having to move. Even if 
spread through decades, that's horror enough. And I haven't even mentioned 
the golden toad yet.
