Undergrad intern AJ Iversen is giving his final presentation today!

Big lakes in the SW US during the last deglaciation linked to tropical Pacific changes in our new Science Advances paper--pointing out importance of better representation of tropical Pacific in models. Thx to Dan Ibarra for help! advances.sciencemag.org/content/4/11/e…

These first-year undergraduates have been working really hard this term in consultation with researchers, students and cultural experts on the Navajo Nation. Excited to see their final project come together for the presentation tomorrow night!

New record shows the last 240,000 yrs of Saharan dust variations track summer insolation, with much less influence from glacial-interglacial changes than previously thought. Great work, Charlotte Skonieczny! advances.sciencemag.org/content/5/1/ea…

Our new paper is out now in Paleoceanography and Paleoclimatology (yes they let in stalagmites now). Check it out for a great story on tropical rainfall dynamics at the edges of the monsoon during the deglaciation. rdcu.be/boUKc McGee Lab @ MIT

NSF is sponsoring 10(!) student and early career scientists to attend the Geochronology GRC. Applications from underrepresented groups are especially encouraged! Info here: tinyurl.com/y34d358d. EARTHTIME EarthRates @DenaSmithNufio National Association of Black Geoscientists @sacnas geosociety

ICYM March's @CafeSciBoston, it's available online! In this talk, @earth2christine and Gabi Serrato Marks, PhD describe their search for ancient stalagmites, relict shorelines, and fossilized algae that serve as natural archives of Earth's changing climate. to.pbs.org/2GDDutf

hi all - it would mean a lot to me if you shared & attended this event tomorrow at 3 EST. Town Hall Discussion: Black Lives Matter-Promoting Diversity, Equity, and Inclusion register here: geochemsoc.org/news/2020/06/0…

🥳 To the entire Earth sciences community — today, we are officially launching... Asian Americans & Pacific Islanders in Geociences (Asian Americans & Pacific Islanders in Geosciences)! aapigeosci.org Help us spread the word, to reach those who need this community now more than ever. ❤️ Learn more: ⏭️

We used cave deposits to uncover the history of Canadian permafrost, finding that thaw was much more common prior 400,000 yrs ago. Like Anton Vaks's results from Siberia, looks like a shift in NH permafrost stability after MIS11. Why? Love a good mystery. advances.sciencemag.org/content/7/18/e…

This flowstone from Bear Cave in Yukon Territory is especially cool--the top layer (where a chip has been removed) dates to 419,000 yrs ago, and appears to reflect the most recent period of permafrost thaw at the Arctic Circle in NW Canada advances.sciencemag.org/content/7/18/e…

Remind your friends that #urgeoscience wants to end with its largest live audience on Monday and that the lineup is pure fire!! :)

Excited to share that a paper I started working on in 🌟2016🌟 is now published, more than a year after I first submitted it! Our dataset is publicly available (of course) if you're interested in mid-Holocene paleo precipitation! doi.org/10.1029/2021PA…

Come help us build a cohort of interdisciplinary postdocs focusing on real-world sustainability challenges! Applications for this new program are due May 28. impactclimate.mit.edu/mcsc-impact-fe…

Excited to announce a faculty job opening in geochemistry and geochronology! Looking for someone to join our department's exploration of Earth and planetary evolution. Please share widely, and feel free to reach out with q's. academicjobsonline.org/ajo/jobs/18978

6 days of sampling beautiful mud Ethan LaComb. Can't wait to see what Searles lake seds tell us about last interglacial climate in southern CA.

These beautiful colors are from Searles Lake sediments! x.com/SFeakins/statu…

#EAPS Prof. McGee (McGee Lab @ MIT) speaks to @ClimateX_MIT about how climate puzzles of the past point to the future bit.ly/2wIVewQ

We use obs, models to explore how trade winds and Hadley circ respond when the rain belt shifts - turns out trades may stabilize the rain belt against large shifts. But more trade wind obs needed! authors.elsevier.com/a/1WDvS-4PRmKv…

Thanks McGee Lab @ MIT for another week of stal dating chemistry. It's been fun and tiring, as usual.
