The extent of global sea ice is more than 1 million square kilometers below the previous record for the current date. This year is particularly a result of the anomalous Antarctic.

Not surprising that today's New York Times article about the singularity launders bullshit for big tech with just enough skepticism for plausible deniability

More impressive: the article quotes 15 different people.

Sundar Pichai
Reid Hoffman
Bill Gates
Elon Musk
Sam Altman
Baldur Bjarnason
John von Neumann
Irving John Good
Hans Moravec
Ray Kurzweil
Rodney Brooks
Jerry Kaplan
Ryan Schaeffer
Eric Schmidt
Charlies Stross

Yes, every single one of them is a man.

I'm missing my old network on the birdsite for this kind of query. Any #archaeology and/or #digitalarchives folks out there with recommendations on curating Ground Penetrating Radar datasets (DZT, DZX)? Challenges: they are v big & proprietary, we don't even have the software to read them in native format. I'm not even sure whether we should accept or recommend curation elsewhere.

@kau Who will record this cover version?! 😄

I keep thinking we've reached the largest anomaly (in terms of absolute magnitude), but that's not the case yet. The #Antarctic departure continues to widen. Apologies if you are tired of seeing me post this same graphic.

It's a fine evening for a dust bath.

I used the CO₂ removal (CDR) as time machine analogy to argue that while we need to research and develop CDR because it’s needed in the future, CDR is useless as a climate solution until we decarbonize drastically.

How it started / How it's going

Yes, same paper. Yes, the first one got a lot of attention at the time. Yes, it was just evidently wrong.

I showed my students this movie of how atmospheric #CarbonDioxide (CO₂) travels around the globe and you should see it too.

What's wrong with the story?

These figures are based on a laughable "fake paper detector" that literally consists of the following ONLY:

1) do authors use private (non-institutional) email addresses and

2) have no international coauthors

That's it.

If these criteria are met, the paper is deemed a "potential red-flag fake publication" and counted toward that 30% tally.

(The authors later also check to see more than 10% of the citations go to papers that also fulfill these criteria.)

My climate change dashboard is updated for this month...

Get this: they can determine the sex and the population-genetical affiliation of a person who lived 20,000 years ago by sampling a pendant she wore. They have no other remains of her body. In recent years we have alse seen ancient human DNA being recovered from chewed birch pitch and floor dirt!
