Are secular correlations between sunspots, geomagnetic activity, and global temperature significant?

Posted on November 15, 2011 by

New paper by Love et al suggests no prominent role for solar‐terrestrial interaction in global climate change. I’m providing it here for discussion. We are not convinced that the combination of sunspot‐number, geomagnetic‐activity, and global‐temperature data can, with a purely … Continue reading →
