At #newscientistlive, we’re bombarded by ads that say: the climate crisis is terrible; fusion is the answer.
Yes, fusion is the answer, but it’s not happening here on Earth but 8.33 minutes away.

Today is my last day at [C]Worthy, the nonprofit research organization that I co-founded to develop freely available tools for verification of marine CO₂ removal (mCDR). I will not be making any public comments, but I now have opinions about mCDR.

I met Dr. David Ho!
He’s responsible for the fact that HIV is no longer a death sentence and his work has saved tens of millions of lives. Why he doesn’t have a Nobel Prize is beyond me. AMA.

It’s fun to be back at Columbia, an institution that I was affiliated with for over 30 years, to discuss marine CO₂ removal.

In the US, PM₂.₅ from wildfire smoke already kills about the same number of people as guns and cars (~40k each), but this will increase significantly with climate change. 😐

I went to the American embassy today to get a passport card that I could carry in my wallet to show my citizenship in case masked men try to kidnap me when I’m in the US. Seriously.

I have an old bike jersey whose zipper needs repair. The quote for the repair is more than the cost of a new jersey, but I'm going to repair it because I want to live in a world where we repair things.

For the last year, there's been an encampment by the Thames across the street from the US Embassy to protest the war in Gaza. I didn't realize how clearly you can see it from inside the embassy until today.

Question for #BikeTooter: I’ve had this bike for 15 years but this is the first time I’ve taken it touring. With this setup where I have most of the cargo on the back, would you inflate the rear tire more? If so, by how much more than the front? Thanks.
