One part of the thing is that oil interests are far too powerful and people are far too complacent. We “could” do something but there is far more short-term economic incentive to not. We could all stop 80% of our polluting tomorrow. It would be super uncomfortable and probably boring, but we have done worldwide action in some form, as we saw in the COVID pandemic. But it’s too convenient to just keep doing what we’re doing.
The other part that I don’t really see this author mentioning is feedback loops. When warming gets to a certain level, it can beget more warming. Icesheets that reflected solar energy back to space is now being absorbed by the oceans. Permafrost melts releasing trapped gasses. The ocean heat currents are weakening.
Now I enjoy optimistic takes. I do think it is possible to turn things around as a planet. But there is an overpowering collection of voices saying “I don’t wanna” that need to be overcome. The natural disasters are still going to have to get worse before people want to do something about it. And I haven’t even talked about human conflicts causing needless suffering.
The author literally wrote one of the commonly-used intro texts about climate.
They’re well aware of feedbacks, and that’s part of the standard understanding that scientists have.
From what I have observed, the jury is still out on whether we are overestimating or underestimating impacts of feedback loops, I’m sure this author knows about them but they shouldn’t be ignored when talking about it for the sole purpose of painting a rosy but unrealistic picture towards a solution.
As my specialty is electrical and not climatology, I’m just hoping to avoid the equivalent of “thermal runaway”. If the planet loses its magic smoke we have no replacement on order. Our window of opportunity to get things under control is still open and there are more technical solutions and a broader range of support for implementing emissions reductions than ever before. There are also countless barriers and obstacles.
It depends intensely on what you mean by “thermal runaway” — we can absolutely create a world which will support a much smaller population; we can’t really create a world where we boil off the oceans like Venus.

We’ve seen a number of crashes in the O&G sector in my lifetime, typically paired with sharp downturns in the economy leading to contractions in consumption.
The COVID shock in '21 illustrates a big part of the problem is the Just In Time supply chain. We have relatively few places to store energy, so a crash in demand can create a big backup in supply. The end result is -$43/bbl oil, because nobody has a place to put the excess. That triggers huge layoffs and creditor liquidations that can rapidly reduce industrial capacity.

I can easily see a future in which US domestic production or Saudi Gulf exports suddenly tank out thanks to a war or another pandemic or a super-storm.
But the end result of a crash like that is enormous human misery for an extended period of time. Would prefer to do things the easy rather than the profitable way.

We know this. We know that if we stopped emitting, we could avoid the worst. We’re not idiots. It’s just that there’s no reason to believe humans will reduce emissions to a significant enough extent.
We’re not idiots.
Hnmm, I’d argue we are.
Well I share some degree of pessimism but the future is inherently unpredictable. There may be a big change coming. We just have to keep fighting so that we’re ready to win when the opportunity arrives.
There are trends and the odds aren’t exactly in our favour. But I generally agree. We’re not certainly doomed. And it’s important to keep fighting!

Humans have and continue to reduce emissions. Just not in the US-dominated economic zones.
Actually, the US has cut emissions already. Just not to zero, which is where it needs to go.

Only via dodgy accounting, Defence arent counted, international flights, international shipping etc aren’t counted at all. Then there is the entire issue that outsourced emsision are ignored, they will go up again if onshoring occurs. Outsourced emissons are worse becase of shipping which isn’t counted at all.
The dodgy accounting is deliberate as Deiter Helm explains.

We’re doing noting to reduce emissions except LARPing. This isnt a tech problem, it’s a behavioural one. Closing aiports, banning private cars, banning cruise ships, cutting the military in 1/2 are solutions ebwryhibg eise is just posturing.
Bit I’ve had this debate with you a decade ago on Reddit and since then the Keeling curve keeps rising an rising.
Yes, worldwide emissions are still rising — largely because of emissions growth outside the US.
And no, it’s not a result of “dodgy accounting” — it’s because of how electrical generation has changed, with a sharp drop in the use of coal.

Even though domestic emissions have fallen 27% in the UK between 1990 and 2014, once CO2 imports from trade are considered this drops to only an 11% reduction. Similarly, a 9% increase in domestic US emissions since 1990 turns out to be a 17% increase when trade is included.
Including emissions outsourced to other countries provides a more complete picture of the true responsibility associated with a country’s actions. It also accounts for carbon transfers associated with the decline of the manufacturing sector in the developed world.
Toxic positivists: Despite the overwhelmingly depressing reality which lies before us, I’m just going to describe anyone that recognises it as mentally unwell, thus invalidating their well-reasoned opinion.
