Now when Senator Fielding goes to confront the formidable Minister for Climate Change and Water, Senator Penny Wong, he might like to refer to this item in the June 11, 2009 issue of Nature or perhaps even to the original reference -- Proc. Natl Acad. Sci. USA doi:10.1073/pnas.0809436106 (2009).

Forget anthropogenic CO₂ emissions; forget cycles of solar flares and spots; don't worry, be happy.
