Solar cycles 24 and 25 and predicted climate response

By: D.C. Archibald

Projections of weak solar maxima for solar cycles 24 and 25 are correlated with the terrestrial climate response to solar cycles over the last three hundred years, derived from a review of the literature. Based on solar maxima of approximately 50 for solar cycles 24 and 25, a global temperature decline of 1.5øC is predicted to 2020, equating to the experience of the Dalton Minimum. To provide a baseline for projecting temperature to the projected maximum of solar cycle 25, data from five rural, continental US stations with data from 1905 to 2003 was averaged and smoothed. The profile indicates that temperatures remain below the average over the first half of the twentieth century.


David Archibald also has an excellent presentation here called "The past and future of climate". Lots of great graphs!
