A thread on Felix Klein, Emmy Noether, and credit where credit is due. Felix Klein gave a lecture at the Mathematical Society of Göttingen #OTD in 1918. The title was “On Hilbert’s first note on the foundations of physics." 🧪 ⚛️ 👩‍🔬
Black and white photo of Felix Klein. He wears a dark jacket, white shirt with a high collar, and a thin black bow tie. Klein has a neat, short beard and his hair is parted on the far right. He is looking just to the right of and slightly above the photographer, with a serious and thoughtful expression on his face.Black and white photo of Emmy Noether. She wears a white blouse with fine vertical stripes and puffy shoulders, and a light gray skirt fastened at the waist with a dark belt. There is a puffy black bow at her collar. Noether's dark hair is pulled back, and she is looking just down and to the right of the photographer. She is standing behind an ornate chair; only the back of the chair is visible in the photo.

This is a very important issue. The success rate of proposals is so low that people spend all their time, writing proposals and not doing actual science. Another way science is broken.

I really don't think this is a great narrative to promote. It's not as if climate scientists haven't been very vocal about the risks associated with climate change/global warming and just because it *might* be faster than some kind of best estimate doesn't imply "confused".

I see that a lot of people still need to look at this infographic about the difference between carbon removal (CDR) and carbon capture (CCS). carbon180.org/blog/the-dif...
Infographic from Carbon180 about the difference between carbon capture and carbon removal titled "Carbon removal is not carbon capture", with the subtitle: "Though the confusion isn't farfetched. Both climate solutions clean up carbon pollution - but differ significantly in methods and impacts."

On the left is a "Carbon Removal" graphic of carbon being sucked from the atmosphere, with a flag "negative emissions" and the words "'Sucks' existing CO2 from the air using land-, ocean-, and tech-based pathways, rather than preventing emissions at the source
Can target legacy emissions and address climate impacts on frontline communities"

On the right is a graphic for "carbon capture," which depicts a sponge on a smokestack of a factory. It has a flag that says "net-zero emissions" and the words "'Scrubs' CO, from a point source - a localized source of emissions, such as a power plant or industrial facility. Lowers or zeroes out the footprints of traditional, carbon-intensive industries"

A four panel meme about the PR around artificial intelligence. In the top left panel, a man looks at a crack in a wall. The crack is labeled "statistics". In the next (top right) panel, the man is shown hanging a picture frame around the crack. In the next (bottom left) panel, the man is shown standing next to the 'framed' crack, which is now labeled "Machine Learning". In the final (bottom right) panel, the man stands next to the framed crack but now a huge audience has gathered. The crack is now labeled "Artificial intelligence".

A shameless plug for my study with a similar recommendation. Considering the full ensemble spread is important for sub-selecting models for dynamical downscaling. Climate sensitivity-based selection doesn't necessarily work well (CMIP5-based, so pre hot-model). journals.ametsoc.org/view/journal...

The regional climate sensitivity of ESMs (dXreg/dTglob) is found to be mostly independent from the ESMs' global climate sensitivity (dTglob/dCO2).

If your country has a lot of hydro power then any installation of intermittent renewables automatically gets grid storage. Every hour on a panel, every rotation of a wind turbine means less water through a dam which is saved for later when the wind doesn't blow or the sun doesn't shine.
