Another Temperature Proxy Record
I recently stumbled over a proxy temperature record for the North East Atlantic - from Waelbroeck et al., 2001
The data along with many other proxy records is in an Excel spreadsheet at http://www.nature.com/nature/journal/v484/n7392/extref/nature10915-s2.xls
This a very rough and ready graph of the data of the last 10,000 years according to this proxy, the nearest one they had to the UK.
Remember the years on the horizontal axis are increasing in the number of years before 1950 so if we take the start of building Stonehenge as the orange line the period of the building is to the left of the line.
Lovely and warm, no sliding the stones down frozen rivers.

Good climate data is available from the Greenland ice sheets (UK Gov publishes a lot of data on this). Correlations with tree ring data seem to support the evidence.ReplyDelete
