Pinned toot

Hello world! Happy to be here, tweeting (whoops, tooting!) about the science we do in my group. here's our latest paper on the Pliocene North American Monsoon.

This is part of a broader project to study past reorganizations of tropical and subtropical hydroclimate during warm climate intervals

I'll be giving a seminar on the Pliocene North American Monsoon as part of the monsoon seminar series in about an hour. Hope to see you on zoom!

Some photos from our HTC (high temperature conversion) furnace replacement in our GC-Isolink this past week (this is what helps us measure hydrogen isotopes, essentially converting organic compounds to gas for measurement in the isotope-ratio mass spectrometer!) @DavidFastovich
and Steph Bullinger are now experts!

Get yourself a collaborator who is thoughtfully strumming an electric guitar while helping you understand the scientific figures you are showing them.

Interesting new out by Leupold and colleagues exploring Indian Ocean warmth during the Mid‐Holocene using coral records from Kenya:

Update: I was fired. I loved working at ORNL's Climate Change Science Institute and am devastated, but am also more determined and hopeful than ever. We have incredible power to affect change together.🌱

I still plan to continue with both research & activism, to the extent possible.

To my wonderful colleagues: My temporary affiliation is LSCE. Please use my personal rather than my work email, which I no longer have access to. Thank you for all of the support so far ♥️

Oak Ridge National Lab fired #ClimateScientist Dr. Rose Abramoff for this protest at the AGU Fall Meeting in December 2022 because she “misused government resources by engaging in a personal activity on a work trip and because [she] did not adhere to its Code of Business Ethics and Conduct.” Nuts.

Here's hoping for the safety of all in harm's way this week out West as #atmosphericrivers keep surging in. But it's important to breath and smile when possible. Here's more imagery as a #SantaBarbara newscaster tried to set up a dramatic #AtmosphericRiver #flashflooding shot by yelling for "canoe guy" to come closer.. "You're the money shot!" I don't envy anyone this job. #extremeweather #media More seriously here's my latest

I'm finally ready to announce that my NSF CAREER proposal is being recommended for funding! My group will be studying isotopic gradients, emergent constraints, and atmospheric circulation in past warm climates. I'm also happy we'll be supporting educational initiatives that support first generation students in STEM, and broaden access to careers in climate and sustainability.

An interesting perspective - I would add that we can also potentially look to basins that had large lakes in warm intervals like the Pliocene

“White scientists are generally more successful at winning federal research money from the National Science Foundation than #Black, #Latino and other nonwhite scientists, a new study finds.

“Lagging the most are scientists of #Asian descent.”

Happy New Year to my favorite pandemic online-teaching student email from two years ago, when my cats were essentially the mascot for all my classes.

For reference, this is the video he sent me:

To peer into Earth's deep time, meet a hardy mineral known as the Time Lord - Geologists rely on tiny crystals of the mineral zircon to understand the timing of key events in Earth's early days, like the rising of continents and the emergence of oceans. #npr

I seem to remember a paper a few years ago showing that if a student asks the first question after a lecture, there tends to be more student engagement with the speaker than if a faculty member asks the first question...but I can't find the original source. Does anyone have the citation?

When people say global warming can lead to "worse" winter extremes what do they mean by "worse"?

I-colder cold extreme?
II - more frequent cold extremes?
III - colder AND more frequent cold extremes?

My null hypothesis would be of a mean shift

IV - warmer and less frequent cold extremes

It's easy to inject sulfur particles to reflect sunlight to cool the Earth.

It's not easy to know whether it can be done safely and effectively.

Definitely not easy to ensure govts & people are ready for it.

A startup has done it anyway 🤦
