If you want something to lift your spirits about how cool science can be, then I would recommend watching Good Night Oppy.

i challenge you to find cooler news today than “despite all odds against American scientific research rn, a CO researcher developed a temperature-stable, single dose rabies vaccine that works bc of particles coated in CANDY & SAPPHIRE, & it could help reduce rabies deaths in places w/o electricity”

Happy (rainy) Tuesday, #Boulder. I've got a new story for you all about a new temperature-stable, single-injection rabies vaccine developed by @colorado.edu researcher Ted Randolph.

I have a new @nytimes.com guest essay w/ @davidkeith.bsky.social about sunlight reflection. We note its not a solution for climate change and at best a band aid to treat systems, and suggest if its ever done it should only be to replace the cooling from air pollution today:

Opinion | A Responsible Way to Cool the Planet

A small, carefully scaled geoengineering program could compensate for the loss of cooling as we eliminate sulfur pollution.

Sunscreen for the planet - Works in Progress Magazine

The world is warming faster than we can cut emissions. But volcanoes already been cool the planet accidentally. If nature can cool the Earth, maybe we can.

Il y a quand même pas mal d'informations trompeuses dans l'étude. Juste pour prendre un exemple : oui, il n'y a pas de soleil en hiver dans les poles, mais le SAI refroidit quand meme les poles en hiver (voir b ci-dessous tiré d'un papier cité dans l'étude (Lee et al. 2023)).

Who would have guessed that putting together your own group of people to write an "assessment" with the specific goal from the beginning to come out with a specific set of conclusions, cherry-picking data, highlighting uncertainties to imply there is no understanding, ...

Unfortunately, the published version still contains many inaccuracies, so much so that it may challenge their conclusion that "further research into these techniques would not be an effective use of limited time and resources"...

Matthew Henry @mattjohenry.bsky.social · 28d

The stratospheric aerosol injection section in the preprint was full of mistakes, misleading statements, and very one-sided.

Matthew Henry @mattjohenry.bsky.social · 28d

More seriously though, it's perhaps a good thing that more scientists are thinking about climate interventions.
Ultimately, the more people get involved, the better our collective answer to whether or not we should intervene will be.
However, we have to be rigorous in our assessments.

Is this a crisis or not? Are tipping point risks serious or not?

Net zero is non-negotiable, but climate impacts are here, and all plausible emissions scenarios see us pass 1.5C.

If now is not a reasonable time to explore radical ideas, when would be?

Why is this so important? It means that our emissions today will not just affect our generation, but countless generations to come. And the only way to permanently cool the planet back down once we stop emissions is to take that CO2 back out of the atmosphere.
