IPCC vs MftF


Intergovernmental Panel on Climate Change vs the Ministry for the Future

Heatwaves at both of Earth’s poles alarm climate scientists
The Guardian, Mar 2022

Antarctic areas reach 40C (104F) above normal at same time as north pole regions hit 30C (86F) above usual levels.

At this time of year, the Antarctic should be rapidly cooling after its summer, and the Arctic only slowly emerging from its winter, as days lengthen. For both poles to show such heating at once is unprecedented.

Scientists warned that the events unfolding were “historic”, “unprecedented” and “dramatic”.

They also said that extreme events like these are exceeding model projections, which is another way of saying that according to our current models, the planet is behaving like it's about 2030 already. 

When the scientists who study this stuff for a living start getting worried because their models aren't even strong enough to capture how fast things are happening, that's when you take note.


COP26: Document Leak Reveals Nations Lobbying to Change Key Climate Report
BBC, Oct 2021

Last year, we got a meta-glimpse of how science really works at the highest levels of global coordination, when a leak of an IPCC draft showed us which parts of the scientific consensus were removed for the final report. 

  • Saudi Arabia, Argentina, Australia, India, Japan, Norway, and OPEC demanded insistence on rapid reduction in fossil fuel be removed from the report.
  • Australia lobbied against the elimination of coal-fired plants, and also lobbied against the mention of lobbying in the report. (Go figure.)
  • Just about everyone said carbon capture isn't real, and scientists should "do their research" (just kidding about the quote, but that's basically what they said).
  • Saudi Arabia said “accelerated mitigation” is a bad idea, and a bad word, and it shouldn't be in the report. 
  • Brazil and Argentina want meat-based diets, and they don't want the report to ask people to not eat meat, even if it might help save the planet.
  • Switzerland doesn't want the rich people to have to finance the poor people to "meet their emissions", which is another way of saying stop using fossil fuel. 
  • India, Poland, Slovakia and the Czech Republic want scientists to say nuclear power is good. 

In the end, the report we got from the IPCC was very much modified from the original scientific consensus. And it didn't contain the words “accelerated mitigation” at all.

Here's another part that was removed -- 1% of the world’s population caused half of aviation’s carbon emissions in 2018 [the guardian]

And with that, I remind folks, for those who have read Kim Stanley Robinson's Ministry for the Future (2020), of Crash Day, the day the war for the Earth began, by mysteriously crashing roughly 10% of all flights in the air, at the same time; people stopped flying in regular airplanes from that day on. For those who haven't read it, read it.

Oh, and what happens next? The majority of the world's meat is intentionally infected with Mad Cow, which stops people from eating meat. Problem solved?

The Quantum Object


Physicists bring human-scale object to near standstill, reaching a quantum state
June 2021, phys.org

I am officially reading science fiction in real time. I have to copy directly from the article to translate the full impact.

But first, a small bit of background -- to stabilize a single pair of entangled photons, even at absolute zero temperatures, has been one of the most important and mind-boggling achievements in science ever. This article is NOT talking about single photons, but macroscopic collections of atoms, an octillion of atoms.

It's the approach that's even more staggering:

Now for the first time, scientists at MIT and elsewhere have cooled a large, human-scale object to close to its motional ground state. The object isn't tangible in the sense of being situated at one location, but is the combined motion of four separate objects, each weighing about 40 kilograms. The "object" that the researchers cooled has an estimated mass of about 10 kilograms, and comprises about 1x1026, or nearly 1 octillion, atoms.

The researchers took advantage of the ability of the Laser Interferometer Gravitational-wave Observatory (LIGO) to measure the motion of the masses with extreme precision and super-cool the collective motion of the masses to 77 nanokelvins, just shy of the object's predicted ground state of 10 nanokelvins.

The scientists say they now have a chance to observe the effect of gravity on a massive quantum object.

"Nobody has ever observed how gravity acts on massive quantum states," says Vivishek Sudhir, assistant professor of mechanical engineering at MIT, who directed the project.

Computing Without a Computer


This is a repeat, but worth it.

I'm reading Isaac Asimov's Opus 100, which details his course through a writing career that changed the world of science fiction forever. In the chapter on Mathematics, he recounts a story called "The Feeling of Power" where a character is trying to explain to a space age military how he can navigate their ships without computers, which are at the time susceptible to enemy interference:

"Nine times seven, thought Shuman with deep satisfaction, is sixty-three, and I don't need a computer to tell me so. The computer is in my head." 
"Computing without a computer, said the President, is a contradiction in terms."

Post Script
Also from Asimov's Opus 100, on the topic of Words:
"New Jersey"
The state of New Jersey is named after the birthplace of George Carteret, who was given the territory by Charles II of England. He was born on the island of Jersey, the largest of the Channel Islands between England and France, and originally called "Caesar's Island" until barbarians garbled it into "Jersey".

Biology Takes Acid

I don't even think this is a chimera by definition, but it looks cooler.

Big week in biology news. Sometimes I read the news and I'm like, What the F is going on...Can't make this sh** up. This really is turning out to be the century of biology.
