For his next trick, Trump's going to spend the rest of the day deleting greenhouse gas absorption bands with a Sharpie! Maybe he can open the atmospheric window wide enough to cool the planet -- thank you for your attention to this matter, Mr. President!

Diagram showing absorption spectra of the most important greenhouse gases (water vapour, CO2, methane, etc.) with % absorption on the y-axis, and wavelength on the x-axis (logarithmic). 
Someone has gone through and drawn heavy black X's over all the peaks on the longwave part of the spectrum (to the right of the visible wavelengths).
Above that is the overall atmospheric absorption peak pattern, and above that is the graph for energy intensity of emissions and the different wavelengths, shown for solar radiation at 5525 K (orange) and radiation emitted by the Earth to space at 210-310 K (blue). The peaks are widely separated.

I found the nature commentary provocative and useful in identifying a target metric with positive framing, but this thread makes a strong case for keeping 1.5C alive. Why not use both?

Bill Hare@billhare.bsky.social · 7mo ago

A commentary in @nature.com argues the 1.5°C temperature limit has “outlived its usefulness” because we’re headed towards overshoot and should be replaced by a “clean-energy shift” metric. That’s the wrong diagnosis. Here is why. www.nature.com/articles/d41...

Like many, I also agree that the pace of progress in global climate action is underwhelming and support the idea of majority voting in climate negotiations by the UNFCCC starting with #COP30. For more read this post by @climatechangenews.com www.climatechangenews.com/2025/09/22/i...

We sent a probe hundreds of millions of miles across space, set it on a tiny spinning asteroid, collected samples, flew the probe back, landed the capsule with samples on time and target, analysed the samples and discovered the building blocks of life. Science rules. www.nature.com/articles/s41...

Samples from the asteroid (101955) Bennu, returned by the OSIRIS-REx mission, include sodium-bearing phosphates and sodium-rich carbonates, sulfates, chlorides and fluorides formed during evaporation ...

Addressing the climate crisis in my community! I've been appointed to the Whatcom County Climate Impact Advisory Committee to help advise the council on all things climate 💪 tons to learn but it feels great to be in a position to make a difference, guide policy, and use my expertise for good.
