Climate Change Worsened Britain's Heat Wave, Scientists Find (nytimes.com) 155

Posted by msmash from the closer-look dept.
The heat that demolished records in Britain last week, bringing temperatures as high as 104.5 degrees Fahrenheit to a country unaccustomed to scorching summers, would have been "extremely unlikely" without the influence of human-caused climate change, a new scientific report issued Thursday has found. From a report: Heat of last week's intensity is still highly unusual for Britain, even at current levels of global warming, said Mariam Zachariah, a research associate at Imperial College London and lead author of the new report. The chances of seeing the daytime highs that some parts of the country recorded last week were 1-in-1,000 in any given year, she and her colleagues found.

Still, Dr. Zachariah said, those temperatures were at least 10 times as likely as they would have been in a world without greenhouse-gas emissions, and at least 3.6 degrees Fahrenheit hotter. "It's still a rare event today," said Friederike Otto, a climate scientist at Imperial College London and another author of the report. "It would have been an extremely unlikely event without climate change." Severe heat has become more frequent and intense across most regions of the world, and scientists have little doubt that global warming is a key driver. As the burning of fossil fuels causes average global temperatures to rise, the range of possible temperatures shifts upward, too, making blistering highs more likely. This means every heat wave is now made worse, to some extent, by changes in planetary chemistry caused by greenhouse-gas emissions.

        Where's the contradiction between making money and lowering CO2 emissions? If lowering CO2 emissions costs money then we can't sustain lowering CO2 emissions for long, at some point we'd all run out of money. So, find a way to make money while lowering CO2 emissions and there's no reason anyone would oppose efforts to lower CO2 emissions.

          The good news for this situation is that the low CO2 options (renewables) are cheaper, even with storage factored in, and not costing in traditional generators carbon pollution. Even before the current spike in the price of hydrocarbons, renewables were crushing it on overnight cost alone. In the long run transitioning to renewables will improve our economies by making the cost of energy lower.

      If an extremely unlikely event occurs once, it's chance. When extremely unlikely events occur routinely, then they are part of a pattern.

      What I find absolutely astounding is the degree to which scientists who get quoted in the media are much more trigger-happy than they were 15 or 20 years ago

      They know a lot more than they did 15 or 20 years ago. They have 15 or 20 more years of measurements. And, we've had 15 or twenty years more greenhouse-effect induced warming.

      to go along with the narrative that whenever bad weather happens, it is perfectly reasonable to not only blame it on agw,

      Occasional extreme events here or there are random. Routine extreme events at multiple locations around the globe are a pattern.

      Is that actually hard to understand?

      but to also imply that passing $climate_change_law will ameliorate or outright prevent the next one.

      A non-sequitur and a change of subject. What we choose to do about climate change has no bearing whatsoever on the question of whether climate change is causing extreme weather events. The argument "I disagree about the proposed solutions so I'll attack the science," is actually saying "I don't know or care anything about the science."

      Back in the day, people were much more careful in issuing prognostications and prescriptions about chaotic systems whose behavior could rightly be analyzed in stochastic terms.

      "Back in the day" people knew less than they knew now, the models were less well verified, and the global warming was less.

      But I guess that caution is out the window and it's okay to put the scientific stamp of approval on (objectively absurd) statements like there won't be anymore blizzards or hurricanes or wildfires or heatwaves if we all start driving teslas and put solar panels on our roofs tomorrow.
