Blaming Extreme Weather On Climate Change
By Paul Homewood
WASHINGTON (AP) — Climate science has progressed so much that experts can accurately detect global warming’s fingerprints on certain extreme weather events, such as a heat wave, according to a high-level scientific advisory panel.
For years scientists have given almost a rote response to the question of whether an instance of weird weather was from global warming, insisting that they can’t attribute any single event to climate change. But "the science has advanced to the point that this is no longer true as an unqualified blanket statement," the National Academies of Sciences, Engineering and Medicine reported.
Starting in 2004, dozens of complex peer-reviewed studies found the odds of some extreme events – but by no means all – were goosed by man-made climate change. This new field of finding global warming fingerprints is scientifically valid, the academies said in a 163-page report released Friday. The private non-profit has advised the government on complex, science-oriented issues since the days of President Abraham Lincoln.
There have been renewed attempts to convince us that global warming is causing more extreme weather. As I have argued before, it is all very well looking at a single extreme event and analysing the impact of warming.
After all, weather is an extremely complex phenomena, and it would be ridiculous to maintain that some events were not affected by global warming.
But what about all of the extreme weather events that HAVE NOT HAPPENED in the same period? Have they been made less likely by warming?
I was going to take a closer look at this, and may still do. However, Ron Clutz has some very pertinent thoughts, including some must read comments by Mike Hulme.
