NASA: solar wind plasma output at a 50 year low

NASA held a press conference yesterday to discuss data collected by the Ulysses spacecraft which indicates a 50 year low in solar wind plasma output.  In addition to the official release linked above, here is a summary by an attendee who also blogs here at WordPress.  These data fit nicely with Henrik Svensmark’s “Chlling Stars” theory.  This is a controversial theory which holds that climate change is primarily dependent on cosmic rather than human activity.  Svensmark’s wikipedia page has good links to both pro and con articles on his theory.

While the weight of opinion in the fields of meterology and climatology is on the side of anthropogenic global warming, it is by no means unanimous.  Many serious scientists question the orthodoxy of climate change.  A good source for serious climate change skeptics is Lawrence Solomons long investigative series for Canada’s Financial Post last year.  The first in his series is here, read through all the links if you want a good grounding in the scientific (rather than the merely social/political/cultural/ideological) skepticism about human caused climate change.
