Solar Cycle 24: Expectations and Implications

Archibald (2006) predicted that climate during the forthcoming Solar Cycles 24 and 25 would be significantly cold. As at late 2008, the progression of the current 23/24 solar minimum indicates that a severe cool period is now inevitable, similar to that of the Dalton Minimum. A decline in average annual temperature of 2.2° C is here predicted for the mid-latitude regions over Solar Cycle 24. The result will be an equator-ward shift in continental climatic conditions in the mid-latitudes of the order of 300 km, with consequent severe effects on world agricultural productivity.
