UCLA Study, Worsening Western Wildfires Man-Made

 


Western North America's rapidly worsening wildfire problem is anthropogenic, i.e. man-made.

A study out of UCLA confirms that VPD, or "vapor pressure deficit," is to blame.

Climate change — and not natural climate variability — is now the primary driver of wildfire risk and will likely continue to plague California and other western states in the future.

“This change,” the authors conclude, “requires urgent and effective societal adaption and mitigation responses.”

The researchers focused their study on “vapor pressure deficit,” the leading meterological variable that controls wildfires. In layman’s terms, vapor pressure deficit “basically describes how thirsty the atmosphere is,” Rong Fu, one of the study’s authors, told the Los Angeles Times. Fu, a UCLA climate researcher, studied the variation in atmospheric circulation from 1979 to 2020.

The mechanism is fairly simple. A hotter atmosphere draws more moisture out of soils and forests. These dessicated forests are 66.7 to 80 per cent more susceptible to fire.

As if we needed another reason to stop extracting and exporting high-carbon fossil fuels such as bitumen and coal, the filthiest and most deadly fossil fuels, but it seems our prime minister will not succumb to prudence or reason.

Here's an idea, a wildfire levy. British Columbia should work out the real cost of these worsening fires - the cost of forest firefighting, the value of the lost forests and the health costs from those inhaling the high PM 2.5 smoke, and then levy those costs on every barrel of bitumen and ton of coal that we export. These are real costs that are offloaded on the public by the fossil energy producers and their political stooges. It is right that they be held accountable for the damage they cause.

While we're at it, send a memo to all those farmers and ranchers on the prairies reeling from drought. Why should they not demand compensation?

Navigating the Minefield of Short-Termism

Image
Its disappearance went largely unnoticed. There was no post mortem, no eulogy, no deep sighs for what had been lost. Posterity slipped from our consciousness as we ushered in the neoliberal era 40 years ago. Populations would now be administered, not led. Grand vision was a quaint artifact of generations past. Besides, the invisible hand of the marketplace would see to all our needs today, tomorrow, forever. Politicians grew smaller and smaller until they shrunk to fit the mold of technocracy.  Like sheep being dipped we were plunged into a world of supply-side economics in which lower taxation and deregulation would deliver manna from heaven. We focused on skinning the economy, and society, right to the bone. Everything would be maximized, nothing would be wasted, not even the offal.  We were surrendered to a world of short-termism. We elected governments of technocrats - grey suits stuffed with wet cardboard - whose horizons were measured in electoral cycles. They would do what they

The Gun We Point at Our Own Heads

Image
  If you're sitting at a table and there's a loaded pistol in front of you, do you pick it up and point it at your own head?  Probably not, unless something has gone terribly, terribly wrong. How would you feel if someone else was holding that pistol to your head? But there is a pistol pointed at our heads and, unless we do something about it, we're goners. It's not a Glock. It's fossil fuels and the industry is slowly squeezing the trigger. Proven fossil fuel reserves are sufficient to generate 3.5 trillion tons of greenhouse gas emissions .  Russia and the United States each have massive reserves of fossil energy sufficient to push humanity through the 1.5C heating limit, sometimes called the "carbon budget."  I have it on reliable authority that Washington and the Kremlin aren't getting along very well these days. After all, if you won't hold the line on nuclear proliferation, you might not be inclined to voluntarily give up a major source of na

The Cognoscenti Syndrome

  There is a group of people I think of as the Cognoscenti, people who are well educated, very informed and of rapidly diminishing relevance. Their ranks include writers such as Chris Hedges and Glen Greenwald. These are people who have honed an almost Puritanical value system, readily finding fault in any direction. They are scathing in their attacks on Republicans and Democrats alike to the point where they become nihilists. They don't endorse. They prescribe. This is where they fail. They're unable to advocate for anything that might resonate with the public whose interests they argue are being trammeled. Donald Trump was bad but Joe Biden is scarcely better. This is where their elitism comes in.  74 million may have voted for Trump but, hey, they didn't know any better. The mob that stormed the Capitol. They were just victims of the system venting their frustrations. All the racism, bigotry, xenophobia, misogyny, white nationalism - inevitable side effects of their oppr
