🎥 New Talk: Why Heat Matters Most in the Solar Geoengineering Debate

At #ArcticRepair2025 our Editorial Director @peteirvine.bsky.social explained why SAI could reduce many climate risks – but comes with potentially serious trade-offs.

The UK just made the world’s biggest investment in #SolarGeoengineering R&D: £45m for 21 “climate cooling” projects via ARIA. We asked experts what it means — and what comes next.

Real-world geoengineering experiments revealed by UK agency Trials will test ways to block sunlight and slow climate crisis that threatens to trigger catastrophic tipping points

I've always been open about my belief that having +research on SRM is good, so to me the ARIA program is very welcome. Most of the funded research is about expanding our understanding of potential outcomes through modeling, obs and engagement. Yes, there are some outdoor scientific experiments:

If that whetted your aural appetite and you want more detailed solar geoengineering news and discussion, I heartily recommend the SRM 360 podcast, hosted by the excellent @peteirvine.bsky.social (on which I occasionally appear, but don't let that stop you)

New Podcast on Public Perceptions and SRM (w/ an appearance from yours truly).

Thanks to SRM360 and Peter Irvine for the invitation to talk about our latest #GENIE research on climate emotions and public perceptions of solar geoengineering in general.

Here's the link for our SRM graphic and the version with the text.
srm360.org/infographic/...

A graphic showing different ways of increasing the amount of sunlight reflected from the Earth. Specifically it shows Stratspheric aerosol injection, marine cloud brightening, space based reflection, surface brightening and cirrus cloud thinning

Does anyone know of an all-methods-at-obce graphic for CDR that is as good as thos one for solar geoengineering by @srm360.bsky.social ?

Aluminium oxide? Calcite? Diamond particles? Sandro Vattioni argues that research into alternative SAI materials could yield more effective results than sulphur dioxide.

#SolarGeoengineering #SunlightReflectionMethods #ClimateIntervention

F I G U R E 3 Emotions about climate change (hopeful, afraid, angry, and sad) across 30 countries, on a 1–5 scale (1 = not at all, 5 = extremely) withN = 30,284 participants (at least 1000 participants in each country); Numbers to the left reflect those answering “1” or “2,” in the middle “3,” and to the right“4” or “5.” Panel (a) shows the results for “hopeful”; Panel (b) for “afraid”; Panel (c) for ”angry”; and Panel (d) for “sad”.

New #GENIE article on #climate emotions at a global level, and how these correspond to support for ten climate intervention approaches. Now available in Risk Analysis (with @liviafritz.bsky.social, Elina Brutschin, Benjamin Sovacool) 🧵

That's true IF deploying solar geoengineering to keep temperatures at some level. However, it could still be useful in delaying warming even if CDR was impossible.

We're hoping that our graphics are useful to others. Let us know if there are any graphics you think we should produce.

What is Stratospheric Aerosol Injection? Dig into the topic in the latest episode of our Climate Reflections podcast. @peteirvine.bsky.social discusses SAI with @danvisioni.bsky.social and Josh Horton.

#SunlightReflectionMethods #SolarGeoengineering

Could researching #SunlightReflectionMethods inadvertently reduce momentum for cutting emissions?

Mitigation displacement – also described as "moral hazard" – is one of the main critical objections to #SRM. How might society react?

#SolarGeoengineering #ClimateIntervention

This is the kind of question that SRM360 is here to answer.

Journalists, policymakers, the public have a lot of questions about SRM geoengineering, and the scientific literature addresses these, but it's very hard to penetrate.

SRM360.org aims to bridge this gap.

Could #SRM undermine emissions cuts?

This is one of the leading concerns around these ideas, and could fatally undermine it.

@srm360.bsky.social has explainers of this and other issues that SRM presents.

Stop emissions, stop warming: A climate reality check Why future warming isn't as "locked in" as you might think

On The Climate Brink: Stop emissions, stop warming: A climate reality check

This is a crucial point because it determines how much warming is already "locked in" and effectively unavoidable.

The answer is very little warming is locked in.
