https://gwagner.com
It’s pronounced juggernaut without the jug.
Gernot Wagner is an Austro-American climate economist at Columbia Business School. He holds an AB and a PhD in political economy and government from Harvard University, as well as an MA in economics from Stanford University. A founding co-director of Harvard's Solar Geoengineering Research Program (2017–2019) he joined the faculty of New York University in 2019, moving to Columbia University in 2022. Wagner writes a monthly column for Project Syndicate, and is the co-author, with Martin L. Weitzman, of Climate Shock, a Top 15 Financial Times-McKinsey Business Book of the Year 2015. He won the "Austrian of the Year" award in 2022, awarded by Austrian daily Die Presse. .. more

Plus just really basic enforcement of traffic laws that all pass benefit-cost analyses with flying colors.
Traffic cameras at every NYC intersection pay for themselves after a couple days. They hopefully won't be needed thereafter, once drivers get the message.

Here’s my quick preview in Espresso, @economist.com’s daily app.
I’ll be posting live analysis during the oral argument in this thread
der einzige Grund, warum die Plattform X in Deutschland noch Relevanz hat, ist Ihre Anwesenheit dort. Ohne Amts- und Mandatsträger wird die Plattform auch für Journalisten irrelevant und mit ihnen für die gesamte politische Blase.
Yes, my "reach" took a hit, but not really. A handful journalists signed up for my email newsletter, a prominent one reached out for coffee. Sanity: way up.
Preaching to the choir here, but this isn't hard.

And yeah, not every country with the money to do geoengineering "might have a democratically elected government acting in the best interest of the planet."
How to make a small donation with big climate impact? "Spend it on yourself!"
I s'pose that's what an economist would say. ;)

As low as Trump’s approval ratings are, they’d be much lower if he didn’t have the help of large swaths of the media

If anything, published science often has an inherent, lower-case conservative bias.

This is how science is supposed to work — not necessarily the retraction, of course, but the self-correcting nature of science.
Key point: 19% GDP impact by 2050 now 17%, well within 6-31% error bound.
