Anthony Watts declares on his blog : USA’s record warm March 2012 not caused by “global warming”
To support this assertion Watts draws on the work of Dr Martin P. Hoerling of NOAA . Hoerling finds GHG forcing "likely contributed on the order of 5% to 10% of the magnitude of the heat wave" which turns Watts's headline on it's head. Dr Martin P. Hoerling is an expert on attribution. Anthony Watts is not. So there's a wide gulf between the words of a NOAA scientist and what the blogger says the scientists said. WUWT cannot reflect the highly nuanced question of attribution. And that's not opinion, that is observation.
