Attention is often focussed on the late 20thC increase in CET, which is in turn linked to IPCC claims that this was when global warming began in earnest. This argument, of course, rather falls flat on its face with the rapid decline in CET since 2006.

Global temperatures are affected by the AMO, or Atlantic Multidecadal Oscillation, a totally natural phenomenon which runs on a cycle of about 50 – 60 years. The AMO has been in the warm phase since the mid 1990’s, but has actually been recovering from the bottom of its cold phase since the mid 1970’s.
