One in five children infected in the recent London measles outbreak were reportedly hospitalised.
Don’t believe the anti-vaxxers when they say “it’s a mild disease” or “it’s better to get immunity naturally”.
It isn’t.

One of the ocean's saltiest regions is freshening: What it means for circulation The southern Indian Ocean off the west coast of Australia is becoming less salty at an astonishing rate, largely due to climate change, new research shows.

Climate change could expose 1.1 billion people to hunger by 2100 (but there’s good news too) – AI modelling study Without rapid cuts to fossil fuels and a shift to clean energy, climate change could drive over a billion into hunger by 2100, hitting Africa hard.

Climate extremes × demographic momentum = famine amplification

Climate change could expose >1.1 billion people to at least one severe food crisis by 2100 under high emissions

Mitigation halves the risk

What the National Center for Atmospheric Research means to the atmospheric sciences Born out of a time of great need for the federal government, NCAR plays a role with few analogues.

Great piece out today in Physics Today on historical origins, contemporary relevance, & fundamental irreplaceability of the National Center for Atmospheric Research, which remains at imminent risk of dismantling for partisan political reasons.

The scientific case is won, the Paris Agreement means all the countries of the world agreed to action, yet it still remains a challenge to shift the dial. Some good news here but depressing that climate change action remains political. 🧪

Ever notice that multiple‑choice quizzes often feel strangely predictable? I recently dug into why answers so often sit in the middle—and what this reveals about our deep, systematic difficulty with randomness. It’s more surprising than you might think. 🧵👇

A new all-electric double-decker Climate Stripes bus has started taking passengers around Reading today.

The bus shows the warming stripes for Reading back to the 1860s and will hopefully help start climate conversations amongst passengers.

A cartoon showing shifting cycling of K and Al. Note that the fluxes indicated by the size of arrows are normalized to show relative changes.

#WeekendReading: Ouyang et al. on the Phanerozoic onset of large-scale continental weathering. It does lean on K/Al, which I am having some issues with, but a good amount of other proxies show up as well. 🧪⚒️

Jeffrey Epstein emailing Peter Thiel: Finding things on their way to collapse was much easier than finding the next bargain. ... Return to tribalism. Counter to globalization. Amazing new alliances.

Definitely seems like they destroyed the country on purpose.

There’s a massive disconnect between important ocean science research and what hedge fund bros think ocean science research looks like.

Let's ask the question: How many times do the following people show up being named in the Epstein Files:

President Joe Biden: 0
President Barack Obama: 0
MN Governor Tim Walz: 0

President Donald Trump: 4,500

I don't think people appreciate the extent to which coral reefs are screwed. Even if ocean acidification doesn't get them, increasing ocean temperatures will. How screwed they are is up to us.

Zack Polanski challenges Nigel Farage to show down debate.

Let's talk about who funds Reform.

Let's talk about how disastrous Brexit has been.

Let's talk about why Gorton & Denton must vote Green & stop Reform.

Why so quiet, Nigel Farage?

Oh.

We promised to throw the kitchen sink at this election.

Well we've definitely voted for the right candidate with the skills for the job!

Hannah & the Greens are taking the fight to Reform.
