Six Random Waves

May 1, 2013

Merchant of Doubt, Joanne Nova, pounces on the opportunity to raise doubt on whether or not CO2 is causing warming. Jo goes a little crazy with excitement and claims there is no “no man-made effect”; a little awkward given the authors state

This does not rule out a warming by anthropogenic influences such as an increase of atmospheric CO2. Such secular effects could have been incorporated by the DFT, e.g., into the 250-yr cycle obtained from M6, and would then not show up as a discrepancy between SM6 and RM6.
