Those of you who have read the recent blog from WUWT may not have noticed that the article has missed a trick about the USA’s record warm March 2012.
There WAS some “global warming" and the "Cause & Effect" was there to be seen by NASA but NOT Anthony Watts and Roy Spencer!
Anthony and Roy, just like the UK Met Office & NOAA mix up "Cause with the "Effect" often, stating the "Cause" of any warming during March was from the Earth and it's Oceans. The "Cause" of "Climate Change" from March was from the "Effect" of the Sun's "solar wind". It's the "Effect" of the solar wind that changed the Earth's climate in that period. The way Anthony and Roy have put their article together misses this point, they make a case for the "Effect" being the "Cause"!
