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...

It's been such a pleasure to watch the development of this paper, and now to finally see it out. I can't wait to see where @jmarkspeterson.bsky.social takes this project next!

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/
