Climate change has been here a long time.

Wow. Most of the climate change discussions I've heard so far talk about the massive disruptions and dislocations that would be caused by 3-5 degree shifts over 50-100 years.

I can't even imagine what a 22 degree shift in 50 years could do to humanity, with 7 billion of us competing for resources.

But were the ones causing global warming right??? No No No I meant climate change.

To me it sounded like the report extrapolated large conclusions from small amounts of data. Data can support a 22 degree temp change in Greenland without saying much about changes elsewhere.

In a different time frame for example, ocean currents shifting due to the formation of the Central American isthmus probably led to large changes in Greenland's climate but not much change in the global climate. They probably should seek confirming data elsewhere. It's interesting but also an awful lot of theorizing to be based on cores from a small area.
