Assistant Prof Senior Researcher at @OSUCEOAS Using ice and cave rocks to unlock the history of Earth's climate
Joined April 2020
I'm thrilled to share our new @Nature paper! We present ice core methane isotope data revealing that past abrupt climate changes likely triggered surges in wildfires, driving rapid methane—and possibly CO2—rises @osu_ice @NSF 🌎🔥 Read it here 👉

Nature - An increase in wildfire extent and related greenhouse gas emissions can be linked to abrupt climatic changes during the last glacial period.

Stalagmites in caves have long been used to understand Earth’s climate past. Now, researchers are using caves to study how wildfires🔥 will burn on a hotter planet. Recently, I joined a trip into one of these caves revealing the deep history of fire: https://t.co/dYvszQYGF6

Wildfires are already changing as a result of climate change but we don’t know what will happen as our planet gets even warmer. The answer could be hidden underground

Installing a SYP autosampler (@wegeochem) at @OregonCavesNPS with @UCDavisResearch PhD student, Kesego Letshele. The autosampler will quietly collect drip water without disturbing the hibernating 🦇 population this winter @OSUCEOAS

The driest place on Earth wasn't so dry over the last 200 kyrs 👀...this review compiles new and old data from 4 sites in the southern Great Basin into a region-wide history of past water availability

ICYMI: Carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory surged to a seasonal peak of just under 427 parts per million in May. An increase of 2.9 ppm over May 2023 and the 5th-largest annual growth in NOAA’s 50-year record. https://t.co/sDZJP8xQdC

🚨 New paper on rapid CO2 rise 🚨 Decadal-resolution ice core CO2 data show abrupt jumps during each “Heinrich Stadial” event of the last 50,000 years. We show these were linked with rapid warming around Antarctica and coupled upwelling and convection in the Southern Ocean 🧵
🚨 New paper alert! Our ultra high resolution gas measurements show that atmospheric CO2 jumped by as much as 14ppm in 50 yrs during Heinrich Stadials. Where did it come from? 👀 We can't say for sure, but the stable isos in ice point to the Southern Ocean

What field work looks like at @OSUCEOAS. OSU undergrad Layne samples dripping water from the ceiling of @OregonCavesNPS to better understand the cave's complex hydrogeology.

New paper alert ⏰ Groundwater recharge was >200% greater in the north-central Mojave Desert during the last glacial maximum
Water-table changes in the southern Great Basin, USA, over the last 350,000 years are 3-4 times as sensitive to recharge changes during drier interglacial than wetter glacial conditions. @SimonSteidle @Speleo_Katee
