All AI is doing is SEVERELY raising the value of books again, because with the countless bot-written articles echoing nonsense as FACTS, human-written books before the 2020s are now the only reliable source I can trust for my biological and scientific research 😭

Fair enough. Withdrawn. Thanks for the correction.

“AI” will save us. Let’s definitely put all our resources into “AI”.

Facebook AI offers insight into “how many donuts are in a dozen?”

How far “off the charts” is September 2025? Sea surface temps are in this area of the North Pacific. >1.6C or ~3F above normal on average over this huge area.
I’d say even more alarming than the actual anomaly is the trend since 2010. In 15 years the anomaly jumped more than 2F! 3/

The most important thing about AI is that after the investment bubble bursts, the class of idiots and conmen that bet the farm on it (many of whom also tried to bet the farm on crypto etc) stop being the people we let decide how our whole society allocates resources.

We had total drought for about six weeks but we’ve had a substantial rain once a week or so for the last little while.

Another event likely tomorrow. Abnormal, very few clouds, so soil is still very dry, but not as bad as you have it.

Nice to be back in touch.

However, referring to deniers in the past dense is extremely over-optimistic.

I have recently been included in two active climate denier groups on Facebook. They are not chastened in any way by events.

Right, as I keep saying, physical reality is under no obligation to be moderate.

But yes, of course imagining impacts in advance is much harder than extrapolating climate physics.

Alas, these are early days. Ecosystems are at the edge of adaptability; they will soon be far beyond that edge.

High latitudes warm faster than other land areas. This was expected in advance. The result goes back as far as Charney 1979 (see excerpt below). It wasn't a secret; rather it was often communicated.

If policy people don't "widely understand" science (clearly they don't!) that's a separate issue.

Text from 1979 paper; includes "All the GCM's predict larger surface delta-T at high latitudes."

Regarding your article - we seem to have taken a turn toward the worst scenario (#3) recently.

People are thinking nationally rather than globally, and the consequences are bad on many axes.

Recent election results in Czechia adds to the list of countries that have shockingly lost perspective.

The persistence/growth of penury under conditions of unprecedented aggregate global wealth is certainly striking!

We have permitted luxury beef cattle to outbid hungry humans for agricultural output. What has failed isn’t “abundance”!

If things get desperate nothing prevents coal from coming back.

Growth may fail, or (consider “AI”) imaginary growth may dominate for some time, but the climate mostly cares how much fossil carbon we burn, not what the balance sheets say.

Official records say no, but it was about 15 C above normal.

Exactly. Very well and clearly stated.

I was for decades a gradualist who insisted than without enough gradual action, gradualism would become untenable.

We’ve hit that point. Physical reality is under no obligation to be moderate.

Still we’re not powerless to make matters less (or more) awful.

Alex Steffen @alexsteffen.bsky.social · 27d

We no longer live in a world capable of delivering an orderly transition — where collective action could limit the worsening of the planetary crisis enough that modest adaptation measures could prevent disruption of societal continuity — but that doesn't mean we've lost all agency.

We will find out what >3C abrupt warming and almost 10 billion people looks like. It’s unlikely to be pretty.

Michael Tobis (mt) @mtobis.bsky.social · 2d

Modest and gradual actions have not been sufficiently implemented while the opportunity existed.

There is no longer any way that the future can emerge in a continuous way from the present. I don’t like this but it’s true.

Physics and biology are under no obligation to be politically moderate.

"All global modelled pathways that limit warming to 1.5°C (>50%) with no or limited overshoot, and those that limit warming to 2°C (>67%), involve rapid and deep and, in most cases, immediate greenhouse gas emissions reductions in all sectors this decade."

#Sufficiency

www.ipcc.ch/report/ar6/s...

Limiting warming to the Paris Agreement targets requires rapid, deep, and in most cases, immediate reductions in GHG emissions. Net-zero is achieved with emissions reductions, as shown in the graphic. Implemented policies overshoot the targets.
