(6.10.2010) An analysis of satellite data challenges the intuitive idea that decreasing solar activity cools Earth, and vice versa. In fact, solar forcing of Earth’s surface climate seems to work the opposite way around — at least during the current Sun cycle. (…)

Contrary to expectations, the net amount of solar energy reaching Earth’s troposphere — the lowest part of the atmosphere — seems to have been larger in 2007 than in 2004, despite the decline in solar activity over that period.

The spectral changes seem to have altered the distribution of ozone molecules above the troposphere.
