Anthropogenic Global Warming agnostic? Usual Suspects don’t include the Sun.

New study released in Proceedings of the Royal Society finds that over the past 20 years, despite global warming continuing apace, “all the trends in the Sun that could have had an influence on the Earth’s climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures.”

Comparing historical data of sun activity including sunspots, magnetic field strength, cosmic ray flux, and total solar irradience, as well as other data (including 2 global mean temperature reconstructions over the past 20 years), solar activity (that would have caused warming) peaked around 1985-87, and has been on the decline since.

In contrast, temperatures, which started on the steep upward path long before the 1980’s, have continued their upward trend.

Count out the sun; round up the usual suspects.
