Washington Post article on STEM cuts at federal agencies. NSF tops it at -42%!

โ€œBetween January 2025 and February 2026, STEM and health employees at science-focused agencies saw nearly 15,000 jobs cut. The rate outpaced cuts among other federal workers.โ€

OPM data - Figure from Wash Post article 19 April. (Where US science has been hit hardest.)

NSF at -42%!

Amazon will pay $20.5 million to settle allegations that two of its Oregon data centers helped contaminate groundwater.

This is exactly why communities across the country are organizing to stop data centers โ€” and winning.

Never doubt your power to change the system.

Keeping a beat wins caterpillars friends in low places Finding a caterpillar with rhythm was โ€œmind-blowing,โ€ suggesting it might be a more widespread part of animal communication than thought.

Caterpillars and ants communicate by dancing. The ants tap out a rhythm that the caterpillar matches. There are caterpillars that ants like to take care of: they protect these caterpillars & their babies & the caterpillars in turn secrete sugary fluid the ants eat. buff.ly/iVtLf8j

The lesson of history is that tyrants cannot be appeased.

Appeasement only feeds their insatiable hunger for power.

Tyrants prey on people who feel unsafe and vulnerable.

But without mass submission, a tyrant is powerless.

Remember this.

Always resist: โ€œWhen finally you surrender to us, it must be of your own free will. We do not destroy the heretic because he resists us: so long as he resists us we never destroy him. We convert him, we capture his inner mind, we reshape him.โ€ (Orwell, 1984)

270 people joined me, and we had a great talk about how to engage our neighbours, friends, and elected officials in climate action using the head-heart-hands model!

(which I explain here: www.astronomy.com/science/solv...)

I will share the recording when it's available.

Only half of calories produced on croplands are available for human consumption, study finds Study: 1/2 of the calories produced on croplands are unavailable for human consumption

This is one of the most important issues with the global food system, yet it is often ignored.

Put simply, we don't actually grow much *food* in our farms around the world. Instead, we grow grossly inefficient animal feed and biofuels.

Congrats to the Project Drawdown team. Looks like a useful update of one of my fav papers, @enviroem.bsky.social et al 2013.

Feeding more crops to people & fewer to animals & vehicles would make it way easier to feed 10B people and end deforestation, stabilize the climate, cut water pollution etc.

The SAVE Act started as a political stunt. Now it's a real threat. As we entered 2026, it became clear that Republicans were set up to lose control of Congress in the midterm elections. What followed was predictable.

Here is what you need to know about the SAVE Act:

1. It started as a stunt to protect Mike Johnson's speakership.

2. It has evolved into a massive voter suppression bill.

3. It won't pass.

4. When it fails Trump will escalate.

5. We will fight and win. www.democracydocket.com/opinion/the-...

Protecting forests is a HUGE climate solution.

It is also a solution to biodiversity loss, protecting watersheds, and improving human health.

Put another way, we could get rid of corn ethanol, switch 30% of the freed-up farmland to solar to generate 100% of US electricity, and use the other 70% of the freed-up land for whatever we want.
