THE HOCKEY SCHTICK: New paper finds solar activity an important influence on climate during the Medieval Warm Period

A paper published today in The Holocene reconstructs sea surface temperatures [SSTs] of the Southern Adriatic Sea during the Medieval Warm Period and finds "clear" evidence of solar influence on climate change. The authors find sea surface temperatures varied closely with 11 year solar cycles. According to the authors, "We observe a clear 11.4 year cyclicity in the reconstructed SST series. Furthermore, there is a good matching between SST and global 14C [temperature proxy] anomalies. This suggests that solar activity might have had an important influence on the local climate during Medieval time."

THE HOCKEY SCHTICK: New paper finds effect of volcanoes on climate has been overestimated by factor of 2, & finds lower climate sensitivity to CO2

A paper published today in Atmospheric Chemistry & Physics finds the cooling effect of volcanic eruptions on global temperature has been overestimated by a factor of 2, due to "prior neglect of ocean circulation" of the natural ocean oscillation the Atlantic Multidecadal Oscillation [AMO]. Consequently, the authors calculate that climate sensitivity to CO2 is about 38% less than claimed by the IPCC. The paper adds to several other recent papers demonstrating that IPCC assumptions of climate sensitivity to CO2 are exaggerated.

Some really funny material from Andrew McKillop.

“Scientists such as Freeman Dyson and Ivar Giaever do not agree – but of course they are ‘only scientists’, of untouchable world renown, so what would they know about climate crisis comparred with a TV journalist (EU climate commissar Connie Hedegaard) or CD salesperson (elitist Richard Branson)?..."
