More evidence the Sun drives climate change

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.

Suggestions of “strong negative cloud feedbacks” in a warmer climate

Plus, a really cool photo, taken from the International Space Station!

I thought this post on clouds and climate modeling below from Steve McIntyre’s Climate Audit was interesting, because it highlights the dreaded “negative feedbacks” that many climate modelers say don’t exist. Dr. Richard Lindzen highlighted the importance of negative feedback in a recent WUWT post.

 

One of the comments to the CA article shows the simplicity and obviousness of the existence of negative feedback in one of our most common weather events. Willis Eschenbach writes:

Cloud positive feedback is one of the most foolish and anti-common sense claims of the models.

 

This is particularly true of cumulus and cumulonimbus, which increase with the temperature during the day, move huge amounts of energy from the surface aloft, reflect huge amounts of energy to space, and fade away and disappear at night.

Spot on Willis, I couldn’t agree more. This is especially well demonstrated in the Inter Tropical Convergence Zone (ITCZ) The ITCZ has been in the news recently because early analysis of the flight path of Air France 447 suggests flying through an intense thunderstorm cell in the ITCZ may have been the fatal mistake. There is a huge amount of energy being transported into the upper atmosphere by these storms.
