Climate change not all man-made

The environmentalists won't let this report get in their way of a socialist/environmentalist paradise. National Post

t'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).[...]

NOAA says Western Canada has warmed by two degrees and Eastern Canada hasn't warmed at all because flows of air from naturally shifting Pacific currents have affected the West most.

The lengthy re-analysis of climate data doesn't dispute that greenhouse gases from fossil fuels cause a warmer climate. But it raises questions about the details: How much warming? How many causes? And why isn't it the same every-where?
