The rise and expansion of reef systems in the Indo-Pacific during the warm and CO2 high Miocene (and decline in the aftermath) will never stop being puzzling to me. Now we have evidence that it also had the biodiversity effects expected. 🧪🌊 Link: https://www.science.org/doi/10.1126/sciadv.aec7264 ​

🌊 Circumpolar Deep Water in the Southern Ocean is shifting poleward (~1.26 km/yr), increasing warm water near Antarctica. Boosting heat flux to ice shelves, leading to increased basal melt and sea-level rise. www.nature.com/articles/s43...

We have a new paper out in Paleoceanography and Paleoclimatology showing that the latitudinal gradient in leaf wax hydrogen isotopes over western North America reflects the mean climatological position of the storm tracks. agupubs.onlinelibrary.wiley.com/doi/pdf/10.1...

🌊 What happens to global temperature after net-zero? New results suggest deep-ocean processes matter: as vertical heat diffusion warms the deep ocean, reduced heat uptake could reverse surface cooling on 100 yr timescales. …the climate system has a very long memory. www.nature.com/articles/s41...

Congrats to Flavia and colleagues on an important (and really tough-to-get) result!

Paper Alert❗️We present the first Oligocene record of orbital variability in abyssal ocean temperature based on benthic foraminiferal clumped isotopes. Temperature changes up to 4 degrees C with a 110 kyr pacing, indicating Antarctic ice-volume at this time was less dynamic than previously thought.

For the first time, scientist discovered that the large up-and-downs in oxygen isotopes of the mid Oligocene were primarily driven by large temperature changes in the abyssal ocean and not, as previously assumed, to enormous changes in ice volume in Antarctica. 3/3 www.nature.com/articles/s41...
