Correlation recently reported between solar/GCR [galactic cosmic rays] variability and temperature in Siberia from glacial ice core, 30 yr lag (ie. ocean currents may be part of response)
Man may be innocent, after all. Jasper Kirkby of CERN [The European Organization for Nuclear Research (French: Organisation Européen pour la Recherche Nucléaire)] explains new research into whether solar activity has caused cosmic rays to indirectly warm the earth:
This talk presents an overview of the palaeoclimatic evidence for solar/cosmic ray forcing of the climate, and reviews the possible physical mechanisms. These will be investigated in the CLOUD experiment which begins to take data at the CERN PS later this year.
UPDATE
A new paper in the Journal of Atmospheric and Solar-Terrestrial Physics also fingers the sun:
In concluding, we find increasingly strong evidence of a clear solar signature in a number of climatic indicators in Europe, strengthening the earlier conclusions of a study that included stations from the United States (Le Mouël et al., 2008). With the recent downturn of both solar activity and global temperatures, the debated correlations we suggested in Le Mouël et al. (2005), which appeared to stop in the 1980s, actually might extend to the present. The role of the Sun in global and regional climate change should be re-assessed and reasonable physical mechanisms are in sight.
