280 million e-bikes are slashing oil demand far more than electric vehicles E-bikes and scooters displace 4x as much demand for oil as all of the EVs in the world.

Want to reduce your transportation emissions?

Skip the EV and go with an e-bike.

“Electric micromobility…[is] actually displacing four times as much demand for oil as all the world’s electric cars at present.”

Bonus: e-bikes are also fun AND healthy 🤯

Bronze plaque saying "A Letter to the Future. Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it.  August 2019. 415ppm CO2"

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque:
"This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

Opinion | Trump Is Squandering the Greatest Gift of the Manhattan Project

The blind destruction of American scientific research by the Trump Administration seems to indicate a lack of understanding about the true origin of many modern technological innovations.

Top-down macro photograph of three blocky, black ants on a white background. All the ants are covered in evenly-spaced, silvery hairs, giving a glittery appearance. The ants at left and center have large, plate-like heads, the one at center, the queen, is quite elongated.

My project this evening was this composite photograph showing caste in Texas turtle ants: soldier, queen, and worker. This is one of those twig-nesting ants whose soldiers serve as living guard doors, using that massive head to block the entrance.

Lovely to see.

The reason there is no official merch is that Watterson refused to license it. Said he’d quit drawing the strip if the syndicate insisted. They gave in.

The central character is a *stuffed animal.* He could have been Charles Schulz level rich.

If you have the specimen in hand; hemipterans are notable for their piercing mouthparts (looks like a needle). The presence of a triangular shaped scutellum is also a clue. Nice ID!

It's been a bit since I've done a meteorological deep dive, but the devastating flash #flood in central Texas this July 4th/5th deserve a closer look. #TXwx

Yes remnants of #Barry were involved helping enhance moisture. A remnant MCV from Mexico on 3 July also played a role.
