Slowly more evidence emerges about the Sun’s influence on Earth’s weather. Slowly more scientists speak out, challenging the faux consensus about climate change. Of course, readers of the FM site already know about this.

(1) “It’s the Sun, stupid“, Lawrence Solomon, National Post, 21 May 2010 — “Solar scientists are finally overcoming their fears and going public about the Sun-climate connection”
Four years ago, when I first started profiling scientists who were global warming skeptics, I soon learned two things: Solar scientists were overwhelmingly skeptical that humans caused climate change and, overwhelmingly, they were reluctant to go public with their views. Often, they refused to be quoted at all, saying they feared for their funding, or they feared other recriminations from climate scientists in the doomsayer camp. When the skeptics agreed to be quoted at all, they often hedged their statements, to give themselves wiggle room if accused of being a global warming denier. Scant few were outspoken about their skepticism.
No longer. Scientists, and especially solar scientists, are becoming assertive.

Solar activity during the current sunspot minimum has fallen to levels unknown since the start of the 20th century. The Maunder minimum (about 1650–1700) was a prolonged episode of low solar activity which coincided with more severe winters in the United Kingdom and continental Europe. Motivated by recent relatively cold winters in the UK, we investigate the possible connection with solar activity.
- We identify regionally anomalous cold winters by detrending the Central England temperature (CET) record using reconstructions of the northern hemisphere mean temperature.
- We show that cold winter excursions from the hemispheric trend occur more commonly in the UK during low solar activity, consistent with the solar influence on the occurrence of persistent blocking events in the eastern Atlantic.
- We stress that this is a regional and seasonal effect relating to European winters and not a global effect.
Average solar activity has declined rapidly since 1985 and cosmogenic isotopes suggest an 8% chance of a return to Maunder minimum conditions within the next 50 years (Lockwood 2010 Proc. R. Soc. A 466 303–29): the results presented here indicate that, despite hemispheric warming, the UK and Europe could experience more cold winters than during recent decades.

My impression is nevertheless that the explanation provided by the Lockwood et al (2010) study reflects real aspects of our climate, especially if the effect is asymmetric. They argue that solar-induced changes in the stratosphere in turn affect the occurrence of persistent wintertime blocking. But one comprehensive, definite, consistent, and convincing documentation of the entire chain causality is still not in place, due to the lack of long-term high-quality observations from remote sensing platforms. It is nevertheless well known that the temperature in northern Europe is strongly affected by atmospheric circulation. Crooks and Gray (2005) have identified a solar response in a number of atmospheric variables, and Labitske (1987), Labitske and Loon (1988) and Salby and Callagan (2000) provide convincing analyses suggesting that the zonal winds in the stratosphere are influenced by solar activity. Furthermore, Baldwin and Dunkerton (2001) provide a tentative link between the stratosphere and the troposphere.
The results of Lockwood et al (2010) fit in with earlier work (Barriopedro et al 2008) and provide further evidence to support the current thinking on solar-terrestrial links. Thus, it is an example of incremental scientific progress rather than a breakthrough or a paradigm shift.
