This is amazing!
Let’s make this new paper appear in a few relevant Bluesky feeds! 👇🏻

New dashboard to visualise CRU-TS country averages (i.e. CRU-CY) for temperature, precipitation, humidity and drought area (using our scPDSI indicator).
(It takes a little while to first load, but is quite responsive after that)

Nice reminder that the legacy of anthropogenic climate change could be LONG. Notice here temperatures still elevated by 3000 CE even in the optimistic scenario's. From this paper: eur03.safelinks.protection.outlook.com?url=https%3A.... 🧪⚒️
New paper led by recent Auburn graduate Sarah Barney and w/ @richardsvachula.bsky.social , where we used charcoal to assess the type of vegetation burnt 🔥 in South China during the late Miocene when C4 grasses expanded (funded by @us-sciod.bsky.social; formerly USSSP)

A new paper by @anaigmendez.bsky.social vin Geophysical Research Letters shows that the oxygen isotope ratio of the annual rings of tropical conifers in Central America records rainfall amount and tracks large-scale tropical atmosphere ocean dynamics! agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Excited to have this paper out showing a strong coupling between Central American tree-ring oxygen isotopes and ocean–atmosphere dynamics (interbasin SST gradients, ITCZ, CLLJ... ). Many thanks to all co-authors!

Had a great time at PReSto workshop @linkedearth.bsky.social on creating and visualising custom paleoclimate reconstructions at the Marina Del Rey, LA this week.

In our new highlighted paper in Earth System Dynamics, we map out the global atmospheric river network along with its main hubs, highways and basins!
What emerges is a surprisingly structured system that we think could open up new perspectives on atmospheric connectivity💨🌧️

The Quaternary Period (the last 2.58 Ma) was characterized by the waxing and waning of large ice sheets in the Northern Hemisphere. Using sediment sequences from the Iberian Margin, we demonstrate tha...
We present a method for low-cost emulation of spatially resolved natural temperature variability at monthly resolution The emulator output's statistical, spatial, and temporal characteristics res...
