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
