Remember why they called Greenland ... green ?
Why most of its newly immigrated / invaded population left again ?
Merely a few centuries ago, that was.
Earth has been warmer for a whopping 90% of its life, so even 2010 hardly qualifies as the warmest year on record - it only is a record if you restrict your records to the onset of scientific research.
Sharks have swum where I now sit.
Yet mammoths have also walked this place !
Earth changes continuously, it's just that people are afraid of changes.
Mostly because we as a species are stupid enough to do things that are very susceptible to even minute environmental changes - like building houses if not cities on cliffs - or near shorelines.
Then we'll wonder why the bloody cliff collapses !
Well, it's just following the rest of the cliff that has long gone down ...
Or we wonder why New Orleans floundered.
Well, that's kind of normal when you build it below flood tide level.
Those warmer periods have lead to explosions of life - and to life itself.
Life has been nearly wiped out a few times before - and it has recovered, minus some species that became unadapted to their environment.
That's the way humanity is headed, and it is not a problem, just inconvenient.
What you should worry about is humanity running out of oil, gas and other resources.
It's being burned at an alarming rate, while it could be used for far better purposes.
