Three years in the making, the #GreaterYellowstoneClimateAssessment is now available at gyclimate.org! Huge thanks to @cwhitlockMSU, Steve Hostetler, @WyClimate for inviting me to contribute to this exploration of climate change in Greater Yellowstone.

Excited to be in the Tetons this week for the release of the #GreaterYellowstoneClimateAssessment and the first of the @uwnps AMK Ranch Harlow Speaker Series!

When I traveled to Wyoming, I had the pleasure of meeting Dr. Bryan Shuman, one of the authors of this research. It's amazing what you can learn from the mud at the bottom of a lake. I hope elected officials are listening to their state's scientists! eenews.net/greenwire/2021/06…

Awesome work by @ecojydrology!
Published! The assumption that vapor and precipitation are in isotopic equilibrium is very common in studies of (paleo)climate, hydrology, and ecology. We evaluate and quantify (Bayesian alert!) uncertainties in the assumption. onlinelibrary.wiley.com/doi/…

Accepted preprint alert! researchgate.net/publication… You know that assumption we usually make about precipitation and vapor being in equilibrium? Yeah, we know it's probably wrong, but _how_ wrong? And are there mitigating factors? Read on and find out! #HydrologicalProcesses

Our synthesis of N. American lake-level data shows the major late-Quaternary hydrologic trends. Shifts in storm tracks and distribution of moisture reveal the novelty of the modern hydroclimate. Currently humid or snowy areas were the driest since 21 ka. doi.org/10.1029/2019GL086412

Data set available on NOAA Paleoclimate archive: ncdc.noaa.gov/paleo/study/28… The N-S moisture gradient of western N. America shifted in response to deglaciation and established the modern hydroclimates of western Canada and the Rockies. @WyClimate
Paleo-folks, in addition to postdocs, I am searching for potential grad students interested in Holocene hydroclimates and either organic geochemistry or sedimentary records of lake-level changes. Please share with anyone interested.

I am excited to search for a pair of postdocs. One to work on GDGTs and Holocene paleoclimates in the Rocky Mountains and one to model microbial biogeography. Part of a larger postdoc search and project. Email me for more info. uwyo.taleo.net/careersection…

I'm recruiting a Postdoc (open now, closing when filled) to work on groundwater modeling coupled to various coastal processes: uwyo.taleo.net/careersection…

First time seeing the Ilulissat Icefjord and WOW. In real time, this video is ~5 minutes. Great start to this year's #fieldwork in #Greenland!

Future college students: UWyoming Geology and Geophysics @UWGG ranked No. 1 on collegefactual.com’s best value list. The rankings take into account the average time to graduate, the quality the school provides, the average yearly cost, & salaries after graduation.

"Researchers tried to replicate the results of those 3% of papers—a common way to test scientific studies—and found biased, faulty results...There is no cohesive, consistent alternative theory to human-caused global warming..." Thanks @KHayhoe et al! bit.ly/2gCh5OP

Fossil pollen can provide a useful reconstruction of Holocene climate: We used pollen-inferred precipitation to simulate Holocene lake-level changes and then the sand content of individual lake cores based on water depth. pnas.org/content/early/2019/…
