Paint that scatters 98% of the light that hits it, thereby keeping indoor temperatures cooler. 😎

Paris should paint their zinc roofs with this paint.

My experience with bike lanes in various countries is that they’re extremely popular with drivers, especially as places to park their vehicles.

If anyone is shocked by increasing sea surface temperatures (SST), they haven't been paying attention.

The SST at Key West is warm but totally expected in a global warming world.

SST will continue to increase as long as we keep burning fossil fuels.

Tweet from Bob Henson Lest anyone think this is some kind of mapping error, SST reports from buoys around the Florida Keys posted as of ~7 PM ET Sun are downright shocking, e.g.: Key West 92.1F Vaca Key 94.3F Johnson Key 95.7F ndbc.noaa.gov

I've worked in this area for the past two decades. Everyone's sharing this scary-looking sea surface temperature (SST) map but SST on the Florida Shelf aligns with what we expect in a warming world.

What's scary is our continued use of fossil fuels.

What if one country’s ocean CO₂ removal (CDR) deployment negatively impacts another country’s fisheries? 🐟

This is what this new study from @altagliabue and colleagues finds will happen.

Yes, because being killed by motor vehicles on the ground isn’t enough.

I don’t care that it’s the hottest day in 100,000+ years. I care about what we’re doing to stop it from getting hotter and to help those least responsible for causing climate change to adapt.

Trains in the UK are ridiculous. In France, you could travel twice as far in the same amount of time and pay 25% of the price.

The world’s largest phosphate rock deposit has been found in Norway. ~90% of phosphate is used in agriculture as fertiliser, but it’s also used in solar panels and lithium-iron-phosphate batteries for electric vehicles.

Maybe Norway can stop exporting oil.

Money is pouring into CDR, with sales rising 300% since April 2023. Supply? Not so much; less than 2% of the CDR purchases have been delivered, and half of them so far have been biochar.

A reporter asked what I thought of CCS. Before we're at zero emissions, the atmosphere doesn't care whether CCS or CDR is used for mitigation. The key is not to use it to prolong fossil fuel use and to truly sequester the CO₂ instead of using it for EOR.

This necessarily means CCS shouldn't be used on electricity-generating facilities that could be replaced by renewables but on truly hard-to-abate sectors like steel or cement. CCS might be unproven, but it's captured way more CO₂ than CDR.
