Short comment on 'carbon trading' climateuncensored.com/what-role-fo...

Paris 1.5°C needs >20% cuts in global emissions every year - starting now!
For Paris 2°C, it’s ~8%.
Which country/company/institution can exceed these rates?
Only those that do have any real “emission space” for carbon trading.

Per CDC source: At internal leadership meeting this afternoon, it was shared that 1,257 people were RIF'd at CDC. Number may not be final. Apparently, chief of staff was unaware that RIFs were going to occur so not clear who is making decisions. (Short 🧵)

The numbers of electric vehicles sold in Europe in 2024 are in:

⚡ 1.45 million new battery-only EVs registered
📈 +32% growth in the total electric fleet
🔋 13.6% of all new car registrations are electric

Europe is going full throttle to a clean future.

link.europa.eu/cNKjkh

A color-coded map of Europe titled "Share of electric vehicles sold in each EU country in 2024," showing the share of battery electric vehicles (BEVs) as a percentage of total new passenger car registrations. The EU average is 13.5%. Countries with the highest shares (>20%, darkest shade) include Sweden (35%), Netherlands (34.5%), Finland (29.5%), Luxembourg (27.4%), Belgium (28%), and Denmark (51%). Other countries like France (16.5%), Portugal (19.9%), and Austria (17.5%) are also in the <20% range. Several Eastern and Southern European countries (including Italy, Spain, Poland, and Czechia) have shares below 10% (the lightest shades).

Australia's Queensland reverses policy, pledges to keep using coal power

Australia's Queensland state government said on Friday it would run coal power plants at least into the 2040s, reversing a previous plan to pivot rapidly to renewables and in turn making national emissions reduction targets harder to achieve.

David Simon, creator of ‘The Wire’, being interviewed by Ari Shapiro (NPR)

SHAPIRO: OK, so you've spent your career creating television without Al, and I could imagine today you thinking, boy, I wish I had had that tool to solve those thorny problems...
SIMON: What?
SHAPIRO: ...Or saying...
SIMON: You imagine that?
SHAPIRO: ...Boy, if that had existed, it would have screwed me over.
SIMON: I don't think Al can remotely challenge what writers do at a fundamentally creative level.
SHAPIRO: But if you're trying to transition from scene five to scene six, and you're stuck with that transition, you could imagine plugging that portion of the script into an Al and say, give me 10 ideas for how to transition this.
SIMON: I'd rather put a gun in my mouth.

Getting to >1000 ppm CO2 in the atmosphere is something we hope we never get to. But in the geological past, those levels were reached... so... what does that do to trees?
They take more carbon, release less water, but grow at about the same rate. 🧪

Link: bg.copernicus.org/articles/22/...

Net assimilation is mildly changed at 1600 ppm CO2 and increases at 6000 ppm, driving a major increase in water-use efficiency. Bar heights are means of 10 guava saplings subjected to different CO2 concentrations. Error bars represent standard errors. P values are from paired t tests, and * and ** indicate differences among CO2 levels at 0.01 and 0.001 significance levels. (a) Net assimilation was calculated from chamber CO2 dynamics. (b) Water-use efficiency was calculated as net assimilation divided by transpiration.
