If you're going to write a paper with an LLM, at the very least remove the 5,000 em-dashes and check your references........
This work does suggest that SAI could reduce AMOC decline. That said, there is some uncertainty around the decline of AMOC, and models don't necessarily capture all the relevant physical processes (e.g. effect of Greenland ice sheet melting on ocean circulation). doi.org/10.1029/2025...
A reminder that this is on at 3pm UTC today, DM for the zoom link if you don't have it.
Deadline coming up for EGU2026 abstracts! www.egu26.eu/session/56947
Even if IMO2020 forcing was quite large, it's not obvious that you would see it in the temperature signal for the first few years, as shown here for constant midlat MCB forcing simulations in 3 models. # of years in red is e-folding time (=time it takes for ~half of the total cooling to manifest).
New paper on Marine Cloud Brightening in the Arctic! Our simulations show that the introduction of sea-salt aerosols brightens clouds in the Arctic and leads to substantial Arctic cooling, which also restores Arctic sea ice. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Using 2 figures from articles cited by Siegert et al, we challenge 2 of their statements on the effect of stratospheric aerosol injection (SAI) on the Arctic: 1/ that SAI is ineffective in the polar winter and 2/ that polar injection locations would be needed to produce an impact in polar regions.
Our 20th 🥳 set of SRM talks is on the 26th September! Check out sites.google.com/view/solarge... for recordings of previous talks and link to sign up to the mailing list.
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)).
Nope, not sure how deep I want to go down this rabbit hole!:) I know Yorkshire Water are making their reservoir data somewhat open source. www.yorkshirewater.com/about-us/wha...
Huh, that's odd, 2022 looks fine(?), at least using this metric. Of course evaporation (hence temperature) should have a role to play I imagine. [Again, not an expert!:)] But you're right about the mega-drought. It seems like a mildly dry winter followed by a mildly dry summer would be pretty bad.
A hose pipe ban has been declared in Leeds from 11th July. I tried to find the last time one was declared and I found one in 1995 (and almost one in 2018). Plotted below is the 3-month sum of rainfall in Bradford (closest weather station), showing minima (or near-minima) for 1995, 2018, and 2025.
Yes, maybe the reservoir levels are better related to the sum of rainfall over the preceding few months, which is what is shown here. 2025 clearly stands out.
Had a play with Met Office station data from Bradford (closest I could find), it does look persistently low for the last few months (though 2025 is provisional, and some of the data is estimated etc).
Please consider submitting an abstract to the session on SRM and GeoMIP! Deadline 13th August!
No, the warming rate is ~0.3C/decade. There is a difference between 1 year exceeding 2C (which is what FT is discussing) and the 20-year average (which we use to define the '1.5C' and '2C' thresholds). Still shocking though!
Next SRM talks are up! Go to sites.google.com/view/solarge... to register for the mailing list and see the previous recorded talks.
GFDL is the GOAT, protect it at all costs. Eliminating it would be such pure utter madness...
Next SRM talks will be next week! Check out the website (sites.google.com/view/solarge...) for mail list registration and recording of previous talks.
