New paper finds another non-hockey-stick in Iceland
A new paper published in Quaternary Science Reviews reconstructs temperatures in Iceland and finds summer temperatures during the 1930's were about the same as at the end of the record in ~2002. Following the 1930's, temperatures plunged almost 2C by the time of the ice age scare of the 1970's, and then recovered to temperatures similar to the 1930's. The authors attribute these climate changes to cycles of natural ocean oscillations [NAO & AMO], and there is obviously no relation to the slow steady rise in CO2 levels over this period.
