How do they know all that? I bet they made up everything but the last 100 years.

A lot of this knowledge is known because lichens colonise exposed rock and a reasonably known rate.  I believe this is how some of the knowledge regarding recent Scottish glaciation /permanent snow patches has been gained.

Wow, look at that recession 15,000 years ago!

Nice,

Chris

Well good cheers.

Rigid Raider: Do you want a serious reply? You can have one if you like

Good grief - glaciation all the way down to Geneva fairly recently!

In geological terms, of course. 

Thanks for posting. Fascinating. 

Hi In reply to Toerag:

I’d love to know the methods they used to produce this.

You can read the full paper on the Cryosphere - it’s peer reviewed and open access.

I haven’t actually read beyond the abstract yet, but off the top of my head it was primarily a modelling based effort using climate reconstructions from the Antarctic (which are considered representative globally for various reasons).
