New paper alert! Spelethem drip cups make promising targets for clumped isotope temperature reconstruction. One for the clumpy nerds.

Speleothem evidence for Late Miocene extreme Arctic amplification – an analogue for near-future anthropogenic climate change? Abstract. The Miocene provides an excellent climatic analogue for near-future runaway anthropogenic warming, with atmospheric CO2 concentrations and global average temperatures similar to those projec...

Afternoon folks. I'm delighted to announce our manuscript "Speleothem evidence for Late Miicene extreme Arctic amplification" was published online today. Happy reading! @speleoseb.bsky.social @thomasopel.bsky.social cp.copernicus.org/articles/21/...

Late Miocene speleothems show significant warming, temperate vegetation, and wildfires in Arctic Siberia Scientific Reports - Late Miocene speleothems show significant warming, temperate vegetation, and wildfires in Arctic Siberia

JUST OUT: A new manuscript from our team shows temperate vegetation in modern Arctic Siberia at a time when the globe was 4.5 degrees warmer. www.nature.com/articles/s41...

Arctic speleothems reveal nearly permafrost-free Northern Hemisphere in the late Miocene - Nature Communications Speleothem records from caves in Arctic Siberia allow for the reconstruction of multiannual air temperatures during the late Miocene (8.68±0.09 million years ago). These temperatures suggest that Eura...

Our team, led by Anton Vaks, have just put out this rather lovely manuscript in Nature Comms showing that the northern hemisphere was permafrost free during a period when temperatures were ca. 4.5 degrees warmer - similar to runaway climate change. Have a look! www.nature.com/articles/s41...

Hello friends old and new. If you're at EGU this year, drop me a line. Or even better, come and see my talk on a six-million-year speleothem derived clumped isotope temperature record of continental Eurasia.
