I love how there are still scientists out there who will not commit to saying that climate change is at least part of the cause of our recent severe weather. July was the hottest on record of any month since such records have been kept, and the last 12 months were the warmest such stretch. This isn’t a new thing here people. How many times do we get to hear “last month was the warmest on record” before enough of us wise up to the problem. The New York times reported this today, interviewing Jake Crouch, “a climatologist at the agency’s National Climatic Data Center in Asheville, N.C.” They wrote “Asked whether the July heat record was linked to rising atmospheric concentrations of greenhouse gases, Mr. Crouch said he could not draw that conclusion.” I get the impression that scientists are afraid to draw the obvious conclusion not because they are scientists but because they are afraid.
At least three scientists, James Hanson, Makiko Sato and Reto Reudy, have been willing to state that climate change is making a difference is out weather. In their report, Perception of Climate Change, they write:
“Climate dice,” describing the chance of unusually warm or cool seasons, have become more and more “loaded” in the past 30 y, coincident with rapid global warming. The distribution of seasonal mean temperature anomalies has shifted toward higher temperatures and the range of anomalies has increased. An important change is the emergence of a category of summertime extremely hot outliers, more than three standard deviations (3σ) warmer than the climatology of the 1951–1980 base period. This hot extreme, which covered much less than 1% of Earth’s surface during the base period, now typically covers about 10% of the land area. It follows that we can state, with a high degree of confidence, that extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global warming because their likelihood in the absence of global warming was exceedingly small.
Note the last sentence. They took some heat for this. There are plenty of people who, mysteriously, continue to look (or not look) at the science and fail to see the problem for what it is. I am a bit mystified by what anyone has to gain by perpetuating the “hoax” of global warming. What scientist wants to be wrong? Why claim something isn’t true? In the science community a falsehood will get found out eventually. It’s not like this is a good thing. That is why it is a problem. Sure, you can call global warming a theory and say it isn’t proven. You wouldn’t be wrong. But you can say gravity is a theory, too. Go ahead and tell people that isn’t real.
Anyway, it has been to hot around here this summer. When we get rain, we get a big storm blasting through. Eighty degrees is now a normal daily temperature. That used to be hot, and plenty uncommon for me. We now use an air conditioner at night too often. What gives with that here? It is not just because we are getting older and can’t stand the same old heat. It ain’t the same old heat. Somebody needs to put in a lake at our house.
Call it controversial. Call it a theory. Call it a debate. Heck, call it Fred. It is not going away. It is hot and the weather is crazy. At some point human caused climate change will be a matter of general knowledge in the United States. We’ll catch up to the rest of the world eventually. In the meantime I am going to go make some cool drinks.
UPDATE: Here is another Times article that offers some perspective on the “new normal” with this gem: “it is increasingly clear that we already live in the era of human-induced climate change, with a growing frequency of weather and climate extremes like heat waves, droughts, floods and fires.” That cool drink is going to come in handy.
