Nearly a week into devastating wildfires in France, officials said that firefighters had encountered a pyrocumulonimbus — a “fire cloud,” or a thundercloud created by intense heat. The phenomenon can spark new blazes and is “unprecedented in France,” officials said. Here's what to know.

Heat From France’s Wildfires Creates a ‘Fire Cloud,’ or Pyrocumulonimbus

A pyrocumulonimbus — a thundercloud created by intense heat — is a phenomenon that can spark new blazes and is “unprecedented in France,” officials said.

New climate models are good and show that, the planet continues warming at the current pace, a snow drought as severe and widespread as last winter’s could occur every third year by 2050, and nine out of 10 years by the end of the century in the western U.S. insideclimatenews.org/news/2207202...

Global Warming Unmakes Winter in the US West - Inside Climate News

A new climate attribution study shows that heating from greenhouse gases could drive extreme snow droughts in the region every third year by 2050.

Wise words from the North. I would add that an insistence on a history of infrequent, stand-replacing fires is as colonial in Southern California as it is in the boreal forest. It’s insisting the land was empty when, in fact, people lived and burned throughout a varied, abundant cultural landscape.

Climate change does not cause wildfires, but hot and dry conditions make them much more likely to spread. In Canada, 9 of the 10 worst wildfire years were both dryer and hotter than normal. And these fires are burning in areas that were historically not managed or suppressed.

I always tell folks you don't need to understand or be part of the fire culture, but you should respect it. These days, that respect includes looking clearly at the climate reality. Until we all do that, wildland firefighters and those they serve are destined to see more bad outcomes. 14/14

The U.S.’s top scientific advisory body issued a report on Thursday backing a growing field of science called extreme event attribution that could help governments hold oil, gas and coal companies responsible for the damage caused by extreme weather.

National Academies Report Backs Climate Change Attribution Science

Attribution science is advancing quickly, researchers said. That could support lawsuits seeking damages for severe events worsened by global warming.

Well, here's something related to wildland fire that I've not thought about before today. Yet another bad outcome of climate change as manifested in fire. I hope to one day see a study that positively surprises me, because these last couple of decades have been a beating.

Increased emissions from wildfires in the past decade have reversed earlier progress made in decreasing US surface-level ozone pollution, a new analysis finds.

Massive wildfires in Northern Minnesota and Ontario will send thick smoke into the Great Lakes, the Northeast, and eventually the entire East Coast over the next few days. The Heat Dome out west will steer this smoke around the ridge and down our way in some form by mid to late week. #ncwx #scwx
