There is a great article in the July 2007 issue of Discover magazine
(0n newstands now!) about global warming. It is currently on-line
here.
It is an interview with Danish scientist Henrik Svensmark and the
research that he has done on how solar activity influences the amount
of cosmic rays received at the Earth's surface and how that in turn
affects the global average of cloud cover. During periods of high solar
activity, such as that which we are undergoing now (according to the
article, the highest level of solar activity in the past 1000 years)
there will be fewer clouds and hence a warmer Earth. No human induced
CO2 activity needed! The interview is also interesting in that it goes
into a little bit how Svensmark has been castigated by some of his
peers because his research goes against the conventional orthodoxy.
