New Nature paper by PhD candidate Julia Marks Peterson! @jmarkspeterson.bsky.social and her COLDEX collaborators published their findings on atmospheric CO2 and CH4 over the past 3 million years based on measurements of ice cores from the Allan Hills, Antarctica. www.nature.com/articles/s41...

Broadly stable atmospheric CO2 and CH4 levels over the past 3 million years - Nature

Blue ice records from Antarctica are used to determine methane and carbon dioxide concentrations over the past 3 million years.

Getting direct measurements of CO2 from Pliocene-aged ice has been a Holy Grail of climate science! A new paper by @jmarkspeterson.bsky.social provides a record of CO2 going back 3million years(!), with (let's say) intriguing implications for anthropogenic climate change doi.org/10.1038/s415... 1/

The NSF COLDEX ice coring team is set up for another field season in the Allan Hills, a windswept region of eastern Antarctica where scientists have found 6-million-year-old ice. Locked inside are the secrets to understanding our ancient climate. I covered COLDEX last year for @sciam.bsky.social:

Inside the Race to Find Earth's Oldest Ice

A global race is on to drill for the oldest known layers of Antarctic ice so researchers can peer back in time to a warmer climate to better understand the planet’s hotter future

I interviewed a scientist in Antarctica this week, as one does. The COLDEX project is looking for the world’s oldest ice and the history of climate change. "When I think about Antarctica, it’s all about sea level rise, and Western Antarctica is the heart of the beast and the crux of our problem.”

Huntington man braves Antarctica to research how ancient ice reveals Earth's climate history

Jacob Chalif is part of a three-month mission with COLDEX — the Center for Oldest Ice Exploration — searching to record the Earth's climate history through ancient ice.
