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?

Up in Smoke. 300 Sq. Mi. of Amazon Rainforest Lost Every Day.

  The Amazon rainforest is disappearing at what should be an alarming rate. 312 sq. mi. or 808 sq. kms. every day. Over the past 30 years humans have destroyed a patch of the Amazon equal in area to the states of Texas and New Mexico . The Amazon – historically a great carbon absorber, since trees take in carbon dioxide and release oxygen – now releases more carbon than it stores, which adds to, rather helps to reduce, our global climate crisis. Deforestation rates decreased slightly from 2004 to 2012. But since then, they’re back on the rise, especially in the past couple of years, since Jair Bolsonaro became president of Brazil. In 2018, as Bolsonaro campaigned as a patriotic man of the people, scientists predicted that once the Amazon lost more than 25% of its tree cover, it would become a drier ecosystem, all because deforestation changes weather patterns (due to how trees respire), which in turn reduces rainfall. Furthermore, as the forest becomes fragmented, areas surrounded...

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...

Who Asks "Why?"

Every time there's a conflict between the Israelis and Palestinians, all we hear is 'why?'  Why, as in, whose fault is this? It's easier to affix blame if you can truncate the event. Pick a convenient start date, something recent. In this case we'll make it either the Israeli eviction of Arabs from Jerusalem or the scuffle that took place outside the mosque in response. If those don't work, let's go for Hamas launching unguided rockets into Israel. That's even better because it tags Hamas with the blame. The nice thing about this approach is you can just keep using it. It goes on and on, just as it has for the past half-century since the '67 war. You can even date this whole mess to the beginning of the occupation of the Palestinian territories. The Israelis are said to have called these periodic wars, "mowing the lawn." The idea is that, every now and then, you have to take these Arabs to the woodshed. And then you keep your powder dry unt...
