This balaclava might improve aerodynamics but it's definitely a fashion violation.

The fires in Hawaiʻi are shocking and horrific, and I appreciate the attention of the global media on my small state.

I just wish when climate change fueled disasters strike areas in the global south, the media would show as much sustained interest.

@IanDSmith Hawaiʻi is the most remote population center in the world.

People associate Hawaiʻi with tropical conditions but rainfall has been decreasing for decades because of climate change, drying out the lush landscape and making it increasingly susceptible to wildfire damage.

It's not fashionable to talk about consuming less as a climate solution because our economy is based on selling us crap that no one needs.

Scientists are accustomed to gradual change.

But for a large part of Wally Broecker's career — based on paleoclimate evidence — he was obsessed with the idea of abrupt climate change that arrives suddenly and dramatically.

Looks like Wally was right.

After cycling in NYC for a week, here are my main conclusions about the bike lanes:

Best thing: The dedicated bike signals and left turn signals on the avenues that stop cars from turning into cyclists.

Worst thing: Motorized vehicles in bike lanes, especially on the bridges.

@MichaelPorter as in motor scooters, etc. Also cars and trucks.

Has anyone thought about whether less Antarctic sea ice means greater air–sea CO₂ flux in the Southern Ocean?

For a talk, I updated the remaining carbon budget figure from The Global Carbon Budget based on a recent publication from Piers Forster and colleagues.

If CO₂ emissions continue like 2022, on January 2024, we'll have 5.25 years to use up the remaining carbon budget for 1.5°C.

Also, by any fair measure, whether it's by population or legacy CO₂ emissions, it's not the rich countries who should get to use the remaining carbon budget. We need to be at real zero CO₂ emission now.

This is obviously false, but what I would like to know is how this ultra-white paint compares against regular white paint that's available now for painting impermeable roofs and lowering indoor temperatures, and what happens when dust gets on the roofs?

Think about how close these people in motor vehicles are allowed to drive at speed next to people on foot, on bicycles, and in wheelchairs when they have no idea where the boundaries of their vehicles are.
