There’s no evidence that offshore wind kills whales. But you know what does kill whales? Commercial fishing kills at least 300,000 whales and dolphins every year.

Sounds like we’re just increasing the carbon footprint of goods from China.

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress, even if we should do a lot more.

Impressive turnout for the No Kings! protest in rainy Westerly, Rhode Island.

In the last few days, I've had many European colleagues tell me that they're not coming to the US for work, and I don't blame them.

The Trump administration's funding cut to Columbia University threatens academic freedom essential for American universities' excellence. It sets a dangerous precedent for political interference in academia that could undermine research and innovation nationwide.

We’re lucky in the US to have so much clean drinking water that we flush our toilets with it.

But imagine turning on your tap and not knowing if the water is safe to drink. With Trump gutting all the environmental rules, that will be our future.

Explain to me like I’m 10 years old: Why would we use our limited renewable energy for carbon dioxide removal instead of using it to curtail the use of fossil fuels?

In South Africa alone, a shutdown of PEPFAR aid is expected to result in the birth of 230 H.I.V.-positive babies per day.

We wrote a thing

Read it or not

I don't care

It's about removing

CO₂ from the atmosphere

With geochemical methods

In the ocean

There’s literally nothing that stops them from calling it Gulf of Trump.

“Never before has the danger of climate change been so evident and the response so cavalier.”

The 20- and 24-month sentences that these activists received are criminal.

We should all look forward to the day when we’ve decarbonized enough that fossil fuel subsidies are no longer the lever by which governments attempt to control consumer prices and inflation.

Turns out LinkedIn is also full of climate denying idiots. They’re just not anonymous.
