2000 years of weather climate.

A new paper published in Nature Geoscience uses proxy data to establish an approximate temperature record for the last 200o years. Here it is graphically:

You can find supplemental information and more graphs in this PDF.

There’s a lot of information to take in here, and I won’t pretend to be able to interpret it all. But at a quick glance, especially in the case of Europe, it sure looks cyclical to me. In fact Europe looks to be running on nearly a 2000 year cycle. Really warm at 0-100 years, and really warm again at 1950-2000. What information there is from Asia seems similar. However, North America seems to lag that cycle somewhat.
