I know nothing matters but “weather research good, climate research bad” is the thing currently driving me nuts
The hate I can at least understand.

The desire to shoot ourselves in the foot, repeatedly, will never cease to mystify me.

1. Some good news at last. This week’s column is about the amazing thing a couple of us stumbled into three years ago, which we’ve now developed into a global research programme. It doesn’t change everything, of course, but it could help change quite a lot. + 🧵 www.theguardian.com/commentisfre...

🌊 Our latest study reconstructs the tropical Indian Ocean during the mid-Pliocene - a past warm world with CO2 similar to today.

A reminder that future oceans may reorganise in ways that reshape ecosystems and the carbon cycle.

Not under her own power anymore, the vessel that revealed more about our planet than most others, the legendary JOIDES Resolution is being towed to a pre-cleaning yard in Lyngdal, Norway.
First pic I've seen of her since stepping off in August 24. Still looking great 🫡💔

Texas is nearing 100 gigawatts of emission-free power (solar, wind, storage, nuclear). EIA reported yesterday that the US will install 50 gigawatts of solar + storage in 2025, 40% of it in Texas. That & much more in today's Grid Roundup. Link in reply.

#Antarctic sea ice is:

⚙️ a global climate engine
☂️ a cooling sunshade
🌀 a pumphouse for currents
🧊 a vast verandah for life
♻️ one of the largest seasonal cycles on Earth
🌬️ highly sensitive to climate variability

🌊 What happens when there's less sea ice?

Great summary of our recent paper on sea level rise during a past warm period and what it means for our future. Thanks, @climateages.bsky.social , for featuring our work.
120,000 years ago, sea levels didn’t just rise
they surged, paused, and dropped in rapid pulses.

Fossil corals recorded it all.
What they reveal could change how we think about our future coastlines.

😓 These are the folks who provide satellite imagery, maps, and geospatial support to American scientists that operate in polar regions where most satellites don’t reach.

FOR DECADES they have done this, supporting critical work.

They have helped me many times. This is terrible. #WithoutNSF
Effective immediately, the PGC is no longer accepting new NSF-supported requests due to a lack of renewal funding. Current work is wrapping up. Please contact your NSF program officer if impacted. We’re grateful to have supported your polar research. Read our full statement at www.pgc.umn.edu

These rocks were retrieved from the first dredge, deployed to a water depth of 2700 metres on the steep eastern slope of the Eastern Bruce Rise.

Further dredges are planned, including to features that may be extinct underwater volcanoes.
