West Antarctic Ice Sheet glaciers underwent at least five major inland retreats during the Pliocene—a period with temperatures similar to projected future warming—suggesting the possibility of meter-scale global sea-level rise in our future. In PNAS: https://ow.ly/I6NZ50XRaap

Paleoclimatologist Jessica Tierney recently published a global temperature record covering almost the past half-billion years. According to her model, 50 million years ago, inland temperatures approached 122 degrees Fahrenheit. www.quantamagazine.org/climate-extr...

speaking as a first-gen, this op ed is very very good. we are powerhouses and it truly is a sign of USHE times if they want to try (are you not entertained?) to erase us.

Back to depressing everyone. We are still trying to figure out exactly how much "safe(ish) space" we still have with athmospheric CO2 to keep temperatures in the "suitable for human habitation" zone. This study tries to narrow it down: between 251 and 666 Gt.🧪 Link: www.cell.com/one-earth/fu...

Collapse of key Atlantic current could bring extreme drought to Europe for centuries, study finds. @swinda.bsky.social That's an under-appreciated impact of #AMOC shutdown, of particular concern given the recent results showing much higher likelihood of this. 1/2 www.livescience.com/planet-earth...

A sub-field of science looks at whether the Atlantic ocean circulation #AMOC has weakened. Direct measurements suggest yes but only started in 2004. So people look at temperature and salinity data. A new study finds a robust slowdown fingerprint at 1000–2000 m depth. www.nature.com/articles/s43...

Sea level doesn’t rise at the same rate everywhere – we mapped where Antarctica’s ice melt would have the biggest impact Well worth a read... theconversation.com/sea-level-do...

One of the creepier geology papers I've read was about how in the end-Permian mass extinction (which is characterized by extreme volcanic CO2 outgassing and warming) the actual kill mechanism might have been when pulses of sulfur aerosols masking the warming rained out and the temperature spiked

📢 New paper on the impacts of AMOC collapse on European hydroclimate. 🌊 We find an AMOC collapse would exacerbate drought conditions across Europe, linked to reduced precipitation. In combination with climate change droughts are expected to become more frequent and severe. doi.org/10.5194/hess...

As the planet warms, what was temperate is becoming tropical, and with that comes the corresponding species. You have biodiversity effects, but biogeochemistry is also altered, with increased nitrous oxide production. 🧪🌊 Link: aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

"Our results suggest that taxa previously identified as extinction resistant may still succumb to extinction if the magnitude of climate change is great enough." 🧪⚒️ Link: www.science.org/doi/10.1126/...

With current pledges, the world's on track for 2.6°C of warming in 2100 compared to preindustrial levels. 10 years ago, before the Paris agreement, it was 3.6°C 20+ years ago, we thought it would be 4-5°C So 2.6°C is better, but the problem is that climate impacts are way worse than we predicted.

I'm super happy to announce that the great Sarah Feakins will be taking over as Editor-in-Chief of Paleoceanography and Paleoclimatology. My term is ending at the end of this year. It's been a terrific adventure since I started in January 2020. eos.org/editors-vox/...

This isn’t the first time corals have faced the borderline of extinction over the last 460 million years, and they have always managed to bounce back and recolonize habitats lost during severe climate changes.
