Meanwhile, in Existential News


With people riveted to the outrage in Ukraine or the Covid rollercoaster or the pump price of gasoline, the existential threat facing humanity has become an orphan.

It isn't that climate change isn't drawing us to the abyss, it is. It's just that we have other priorities. We always have other priorities. We'll get to it eventually or "they" will think of something.

Here's the latest. A bi-polar heatwave. We've had them before when in the dark of Arctic night surface air temperatures got into the double digits. But heatwaves at both poles, at the same time? Oh dear.

Startling heatwaves at both of Earth’s poles are causing alarm among climate scientists, who have warned the “unprecedented” events could signal faster and abrupt climate breakdown.

Temperatures in Antarctica reached record levels at the weekend, an astonishing 40C above normal in places.

At the same time, weather stations near the north pole also showed signs of melting, with some temperatures 30C above normal, hitting levels normally attained far later in the year.

30C and 40C heatwaves. That's far higher than the record setting "heat domes" that savaged British Columbia last June. 

Even the climate science types didn't see this one-two punch coming.

The danger is twofold: heatwaves at the poles are a strong signal of the damage humanity is wreaking on the climate; and the melting could also trigger further cascading changes that will accelerate climate breakdown.

Mark Maslin, professor of earth system science at University College London, said: “I and colleagues were shocked by the number and severity of the extreme weather events in 2021 – which were unexpected at a warming of 1.2C. Now we have record temperatures in the Arctic which, for me, show we have entered a new extreme phase of climate change much earlier than we had expected.”

We've been warned all along that climate change is not a linear process. It's a matter of tipping points, positive feedback loops and knock-on effects.

    I read about this earlier today, Mound, and was quite alarmed by its dire implications. It seems that humanity is only able to respond to one crisis at a time, and that crisis has to be immediate and acute to hold our attention.

    My deep pessimism is in ascendency.

    Was Putin baited into his Ukraine blunder?

    I know many find that hard to accept, but when you see the outcomes, it certainly looks very providential to the carnival barkers:
    * telling us to re-arm.
    * telling us 'all the green stuff was/is a mistake'. (yesterday's G&M/Joe Oliver for ex)

    Getting to any form of global unity on going green was always a long shot ...
    ('Canada should not limit fossil fuel production cause someone else will seize the opportunity.') ...
    but united global action, a prerequisite for survival, is. for the foreseeable future, impossible. Now expanding fossil fuels is cast as a patriotic activity.

    A very convenient war, indeed.

    It's a witches' brew, Lorne.

    Cognitive dissonance laced with hypocrisy on a foundation of indifference.

    We're still headed over the cliff, Mound.

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

Image
  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...
