A Nutrient Effect on the TEX86 Paleotemperature Proxy Nutrient stress alters GDGT distributions in marine sediments, resulting in elevated TEX86 ${\text{TEX}}_{86}$ values beyond those related to thermal effects Paleoclimate case studies from the Ar...

Now published in @agu.org Geophysical Research Letters!

What happens to marine archaea when they’re hungry? And what does that mean for the TEX₈₆ paleothermometer?

Thanks to my coauthors and mentors for their support — and stay tuned, more is coming!

An Ancient Warming Event May Have Lasted Longer Than We Thought - Eos New research on the Paleocene-Eocene Thermal Maximum used probabilistic analysis to learn more about its duration and how long modern warming could affect the carbon cycle.

Understanding the duration of the Paleocene-Eocene Thermal Maximum could help scientists better understand the potential effects of modern anthropogenic climate change.

Simon has arrived at the site. He stands on the boardwalk that cuts through the reedy fen. In the background are trees, including some slowly encroaching carr.

What a day. While I was in Bristol for a wonderful PhD viva, the CERES gang was out at Crymlyn Bog in Wales, collecting a 8.5 m peat core. We're keen to see whether deep fen microbes are similar to those we've seen in bogs and tropical swamps and what that means for the resilience of deep carbon.

Thanks @climategordon.bsky.social 😊 Couldn't have done it without you!

New paper led by Emily Hollingsworth in Geochemical Perspective Letters. We use Raman spectroscopy to evaluate rock organic carbon oxidation during the Paleocene-Eocene thermal maximum and assess its role as a positive feedback mechanism! (1/3)

Why peat is a key ingredient in whisky and the climate crisis Whisky production involves the burning of peat, but damaging peatlands releases stored carbon back into the atmosphere where it adds to climate problems.

For "peat heads" - including scientists and whisky lovers!
Interesting article by Toby Ann Halamka and Mike Vreeken.
