Here’s an interesting report from the “pedigree” US Climate Change Science Program (heavily backed by NOAA).
And a news description of it from the good ole’ National Post:
I sort of remembering seeing a brief press release on this in December (when it was issued), but I certainly didn’t understand that it was associated with such bombshells as:
“It’s wrong to blame our warming climate on human pollution alone, says a major analysis by U. S. climate scientists who say North America’s warming and drying trend also has important natural causes.
Natural shifts in ocean currents have caused much of the warming in recent decades, and almost all of the droughts, says the U. S. National Oceanic and Atmospheric Administration (NOAA).”
