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!

Senior undergraduate Claire Rubbelke helping train our new researcher, Lucy, on how to separate biomarkers

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!

Two people crouched over a metal contraption that involves two furnaces, one of which is designed to hold a combustion reactor the other of which holds a pyrolysis reactor. They are connecting up a thermocouple and power leads.
Internal set up of our GC-isolink device housing both reactors, with PI pointing out the design features of the old (broken) HTC furnace.

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

The PATCH Lab v1.0: A database and workspace for Cenozoic terrestrial paleoclimate and environment reconstruction

In the last two decades, analytical advances and a growing interest in relevant research questions has brought a rapid increase in the amount of stable isotope data used for reconstructing terrestrial paleoclimates and environments. As the spatial and temporal resolution of proxy data continues to improve, the quantitative interpretation of these data is becoming increasingly common. These advances in data resolution and theory bring opportunities for multi-proxy comparisons, synthesis and modeling of large datasets, integration with paleoecological datasets, improved climate model benchmarking, and more. Here, in an effort to support these growing avenues of research, we present The PATCH Lab (Paleo-Analysis of Terrestrial Climate and Hydrology)—an online portal to discover, download, and quantitatively analyze deep time (![Formula][1]</img> Ma) terrestrial stable isotope data. The PATCH Lab portal hosts a new database that currently includes 27009 stable isotope measurements from 211 publications spanning multiple terrestrial proxies, and quantitative models for interpreting water isotope and soil carbonate data. Data query, download, and modeling results are organized into user-friendly graphical interfaces that export datasets as .csv files. New data can be easily submitted to the PATCH Lab curators through the portal by completing a data submission template. The PATCH Lab, with the help of community engagement, serves as a resource for archiving terrestrial stable isotope data, building paleo “isoscapes”, and increasing accessibility to quantitative methods of investigating terrestrial stable isotopes in paleoclimate.

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!" youtu.be/Hy2DcRcf96k?t=5943 I don't envy anyone this job. #extremeweather #media More seriously here's my latest update:revkin.substack.com/p/californ

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.

@hasmis @xo yeah that’s outside my expertise :)

@hasmis @xo I should have spoken more precisely.

There are actually former lakes in arid regions of the western US that were likely much larger during past warm climate intervals, and indeed even cool intervals. Paleoclimate scientists, including my group, are working on understanding what drove greater water storage in these lakes during intervals like the Pliocene or last Glacial Maximum, and what lessons we could learn for the present. If you're curious, here's a couple recent papers from our group that address this topic:

For those of us that work with geochemistry or models to understand past change, the editorial proposes an interesting potential application of our work! But lots of details remain to be worked out...

@hasmis @xo whoops - meant to say Pliocene and last Glacial

Tripti Bhattacharya

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.”
