Note the Y-axis here. And also note the scale - thats a change of 310 ppm to 390 ppm. ppm = Parts per MILLION.

Yes, the 'perma' part means it stays frozen in summer. The permafrost in Greenland has melted before. How do we know ? Well the Viking settlers there buried their dead. Its kind of hard to do that, or indeed start farming, when the ground is frozen solid, so it must not have been at the time they were there.
It got a lot colder (the LIA) so they left. Why is it called Greenland ?

This is not normal. |
These are not normal, but at the same time none of these events are totally unknown in those parts of the world.
We had flooding in the UK a few years ago and the standard was to blame AGW. The fact we built on natural flood plain obviously has nothing to do with it.
In 1947 in the UK we had one of the coldest winters on record. In 1948 there were several floods and disasters.
As I tapped, these things are unusual but not unknown.
