Lemonick has just posted a correction to the article - he had got the relationship between cosmic rays and climate back to front.
Michael Lemonick has an interesting article about the role of the sun in climate, inevitably discussing Svensmark's work. This has the feel of further jostling for position ahead of publication of the results of the CLOUD experiment.
[Svensmark's] idea is far from outlandish on a theoretical level, and lab experiments at the European Organization for Nuclear Research near Geneva have shown that this can actually happen. Moreover, Svensmark and several collaborators have claimed to see a correlation between the sunspot cycle and cloud cover — more clouds when the Sun is quiet, fewer when it’s acting up.
