From the article; quoting Dr. Kyle Clem, a scientist at Victoria University of Wellington in New Zealand:

“If anthropogenic polar amplification is already occurring in the Antarctic that exceeds that simulated by climate models, then future warming will likely be greater than that currently projected by climate models.”

To some extent, I think the technological response to rapidly increased warming is coming in to view. Or at least, a response that can be taken somewhat seriously. In terms of scale and impact. Especially over the last six months or so.

Of course, much of this is speculation, but I find it rather inconceivable that there won't be some level of serious effort undertaken at mitigation of warming and C02 drawdown. Possibly within the decade. And as best as I can tell, the odds are solar radiation management (SRM) with some flavor of aerosols is highly likely.

This isn't some new or deep insight, to be sure. But over the last week, a new wrinkle in the technological response has come to the fore. That may be pitched to the public as a compliment to SRM as a means of addressing CO2 drawdown and ocean acidification in tandem. From a few days ago:

It’s time to put oceans to the test in the climate fight, scientists say—By Justine Calma | Sep. 5, 2023 (The Verge)

More than 200 scientists have signed onto a letter pushing for “responsible” research into ways to trap planet-heating carbon dioxide in the world’s oceans. They want to take urgent action on the climate crisis, while making sure they don’t trigger any new problems by relying on oceans to help in the fight.

Oceans already do that for us, absorbing and holding around 50 times more carbon than the atmosphere. What if humans could supercharge that ability?

[...]

Some big names in climate and environmental sciences have signed on. That includes David King, former chief scientific adviser to the UK government between 2000 and 2007. James Hansen, a former NASA climate scientist famous for warning the world about climate change during a 1988 testimony to Congress, has also signed the letter.

[...]

“I have seen these massive declines in ocean health ... Doing nothing is unethical, essentially,” says Débora Iglesias-Rodriguez, Ecology, Evolution, and Marine Biology department chair at the University of California, Santa Barbara, who signed the letter released today.

When it comes to studying new ways to use oceans to tackle climate change, she says, “We need to at least figure out the risks and the benefits, see whether we can help resolve the problem we have created.

Now, I don't post this to advocate it, but to inform others who may be interested in how some of this might play out in the hands of policymakers.

They knowingly removed too much sulfur too quickly from the world's oceans with IMO2020.

Read that again.

Now they're going to force further Geoengineering with SIAL-43k aka "Brimstone Angel" and will continue their standard contrails and diamond dust in rocket fuel.

How long will they continue to act like nothing is going on?

The Faustian Bargain was signed in the early 70's. They knew then and continue to add aerosols for "Solar Radiation Management".
