Even though 100 years and 100 ppm CO2 ago it was as hot/hotter.
Andrew Freedman writes at Climate Central:
While each heat wave has ties to short-term weather variability, increasingly common and intense heat waves are one of the most well-understood consequences of manmade global warming, since as global average surface temperatures increase, the probability of extreme heat events increases by a greater amount. Data already suggests that heat waves have are becoming more common worldwide.
One study, published in the Proceedings of the American Academy of Sciences in 2012, found that the odds of extremely hot summers have significantly increased in tandem with global temperatures. Those odds, the study found, were about 1-in-300 during the 1951-1980 timeframe, but that had increased to nearly 1-in-10 by 1981-2010.
Another study to be published in the journal Geophysical Research Letters found that manmade global warming has increased the chances of Australians experiencing extremely hot summers by more than five times, and is likely to raise the odds by even more in the coming decades. Australia experienced its hottest summer on record in 2012-2013, which also featured destructive wildfires and floods.
The heat in the West during the weekend and during the first week in July will also affect inland areas of Southern California and the state’s Central Valley, where excessive heat watches and warnings have been issued for temperatures in the 100s Fahrenheit. The NWS said on Thursday that the strong heat dome may migrate northward through the 4th of July holiday, potentially locking the near-record high temperatures in place for a week or more, raising the risk of wildfires, and bringing a heat wave to places like Salt Lake City, Boise, Portland and Seattle.
Selective and exaggerated in all respects. What about the cold European and Alaskan summer of 2012? Problems of exaggeration in the studies cited and in the reporting of them make it exaggeration squared. If, maybe, possibly, whatever you want to believe.
It’s also doubtful that the period of 1951-1980 had 30 times fewer extremely (judgmental word warning) hot summers than 1981-2010. And if so, what does that mean really? How about, say, 1911-1960 v 1961-2010? The shorter the period, the more influence of one end of normal cyclical data.
Meanwhile, the forecast highs for “out West” in Dallas are 99, 92, and 87. Dallas in summer. The Horror. The Horror.
Vegas climate: it gets damn hot in summer.
It still gets damn hot in summer. No climate change.
High pressure is just another example of extreme weather caused by climate change.
Being that I live in the Phoenix area, the local weathermen have explained that high pressure is the cause of the heat wave over the southwest. I have never heard the global warming zealots link high pressure with humans putting carbon in the atmosphere.
They blame virtually everything on climate change–except tornadoes. It gets hot, it’s climate change. It snows, it’s climate change. Humans are always to blame.
Now, if suddenly the climate change people said humans had nothing to with the heat wave, that would be news.
“increasingly common and intense heat waves are one of the most well-understood consequences of manmade global warming, since as global average surface temperatures increase, the probability of extreme heat events increases by a greater amount.”
Global mean temp goes up a fraction of a degree in generations, and it causes EXTREME HEAT EVENTS !!!! So Vegas is 117 degrees, instead of 116 degrees.
