30 years ago today, Netscape announced a new programming language, one that emerged from a frantic, week-and-a-half-long sprint. It ended up sticking around far longer than anyone could've expected.
In 1995, a Netscape employee wrote a hack in 10 days that now runs the Internet
Thirty years later, JavaScript is the glue that holds the interactive web together, warts and all.

We have reached 1.4 degrees celsius #globalheating according to NASA data (smooth black trend line). Breaching 1.5 is now inevitable. From now on the fight is to keep overshoot as small and short as possible.

Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

🐦 Bird losses driven by common species declines
A major new study finds North America's bird decline is not just about rare species, it is the common birds that are disappearing fastest, mostly due to land-use change.

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

On the same day, I read about EU wanting to "cut the the eco-related red tape" and this. Crystal blue lakes in Greenland turning brown and becoming CO2 sources, not sinks. Just like that, abruptly. But yeah, let's keep worrying about "competitiveness" and "red tape".

My lukewarm reaction to all the debates around "making Europe competitive again", "listen to Draghi" and "why so much regulation" are pretty much summed up by this - in a not-so-long run, it's just not gonna matter.
I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely.
