Thinks for the link.

If true, this has great implications for the debate over whether humans are causing global warming, or whether it is a natural phenomenon.

Nice coverage -- of the writer's ass. ;') It's refreshing to read something by a real journalist, instead of by a leftwing nitwit shilling for dema-gore-guery.

Thanks hennie pennie for the ping, and neverdem for the pings:

Looking at the correlation between sunspot activity (which is a measure of solar magnetic field, which affects cosmic rays hitting earth) and climate, we see that the Dalton Minimum and Maunder Minimum coincided with colder weather:

Looking further, we can get a rough idea of cosmic ray bombardment by looking at variations of carbon-14 levels:

The global warming hoaxers seem to have no explanation for what has happened in the past.

Typical response: That was different.

Thank you, that is a very useful graph.

Didn’t cosmic rays change Reed Richards and his friends into the Fantastic Four?

Thanks for the graphs!

They pretend the world began in the last 100 years or something.

In NC schools, the world began in 1877.

Thanks for this one, since I'll be making a blog on Pleistocene climate change eventually. This does appear to be an unpublished missive. The Sime et al. (2009) paper is of particular interest to me. So I'll be taking a longer look at this -- it would be nice if scientists far more steeped in climate change knowledge would take a look at it, too.
