Solar Dynamo Still Anemic, Magnetism and UV Lax

radioweather writes "While we are well along into solar cycle 24, there remains a significant gap between the predictions of where we should be, and where we actually are in the progression of the cycle. Recently, the sun went spotless again, and the solar Ap geomagnetic index, an indicator of the solar magneto, hit zero. It is something you really don't expect to see this far along into the cycle. In other solar news, scientists monitoring the SORCE solar satellite have found that solar ultraviolet emissions have dropped significantly in the past few years. The Solar Irradiance Monitor on the satellite 'suggests that ultraviolet irradiance fell far more than expected between 2004 and 2007 — by ten times as much as the total irradiance did — while irradiance in certain visible and infrared wavelengths surprisingly increased, even as solar activity wound down overall.'"

Except that Piers Corbin is not a climatologist, is a borderline quack, and none of his "research" in this area is backed up by peer reviewed articles.

Now add to this that the past three winters have actually been some of the warmest winters (especially in the arctic) we've had, there is nothing very "harbinger" about it. Warmer winters mean more precipitation, which is what we've been seeing. Currently, there are wide swaths of the arctic that are as much as 20F warmer than their average, hence for the first time on record there has actually been an arctic ice REDUCTION in winter which you can see for yourself here http://www.iup.uni-bremen.de:8084/amsr/amsre.html, or you can go by ice volume here http://psc.apl.washington.edu/ArcticSeaiceVolume/IceVolume.php . In addition, global temperatures have still been rising even during a solar minimum. Even with the moderate La Nina we're still having near record warmth for the globe.

I think I'll continue following the consensus of the body of climate science, thanks.
