Nailing the solar activity – global temperature divergence lie

Posted: July 21, 2010 by tallbloke in solar system dynamics

We are frequently told that the Sun can’t be responsible for late C20th warming because temperature has increased while solar activity has dropped from it’s peak in the 1950′s.

What a load of rubbish.

Solar cycle amplitudes are only part of the story. The cycles in the late C20th were short, ~10 years, and high compared to the long term average of ~40 SSN. The minima between them were short too. So although they did reduce in absolute amplitude after the ’50s, they made up for it by kicking out more energy more of the time. Last year to get a handle on this, I integrated the total sunspot areas as a running cumulative total departing from the long term average…. (Source location)

That is quite convincing, isn’t it?
