1/10 What if philanthropy worked more like thoughtful investing—making bets based on evidence, not emotion? @HeatmapNews chronicles how this approach unlocked $100M+ in climate funding: https://t.co/wSS0OOi1Vh🧵

My first op-ed is out today in @washingtonpost, co-authored with my fantastic colleague @cpruhl! We write about the need for civil defense—especially against new biological threats ☢️

In the @washingtonpost today, @hannahxyang and I argue that it's time to bring back civil defense -- starting with next-generation pandemic preparedness.

... we even think this "right-of-boom" framework can apply to certain AI risks as part of a defense-in-depth approach to catastrophic risks. (https://t.co/NT7K9UDPHF)

1/13 As the new Admin pursues a flurry of executive orders and Congress gets ready for a tax fight deciding the future of the IRA, 2025 is poised to be a defining year for US climate action.

What really matters?

Our new @FoundersPledge report "All In”, covers this question head on.

Scary report, just in time for Halloween:

[Global Shield @globalshieldhq]

Today is a meaningful milestone. @RAND has published its global catastrophic risk assessment, which forms the basis of a @DHSgov report to Congress. The findings paint a clear picture: the risk of a global catastrophe is real and only growing this decade.

Are we really still doing this, @AP?

Who are these “many analysts”? What specific barriers do they claim North Korea have to overcome? Or are they just really psyched to witness a nuclear test over the Pacific?

Can't wait to join this great group in DC @CSRisks later this week!

[Foreign Affairs @ForeignAffairs]

Roger Brent, T. Greg McKelvey, Jr., and @JasonGMatheny discuss the risks posed by human-made pathogens—and urge states to start hardening their societies to protect against these biological threats now.

Was lucky enough to be at this @CNASdc (@StaciePettyjohn @kcirtem @PhilSheers) TTX last year, and it's been living rent-free in my mind ever since...
