Sharing a monologue I recorded for USC's 20th Anniversary Conference on Dams in which I reflect on how #dams have been both a blessing and a curse in American West, & how shifts in #hydroclimate amid #climate warming will further accentuate that duality.

Speleothems, or dripstones, are excellent climate archives because the chemical composition of the calcium carbonate in speleothems changes with the climatic conditions above the cave. (photo/©: Hubert Vonhof)

schematic / model graphic - Key processes along the AAA hydroclimate pathway, reflecting how the regional water cycle is linked through continental hydrology, moving water from the Andes to Amazon to Atlantic, and through large-scale atmospheric circulation, moving moisture from the Atlantic to Amazon to Andes. These processes along the AAA pathway underpin social–ecological systems within and beyond the Amazon basin boundaries.

“Py3DEP is a part of [PyGeoUtils] HyRiver software stack that is designed to aid in hydroclimate analysis through web services. This package provides access to the 3DEP database which is a part of the National Map services. The 3DEP service has multi-resolution sources and depending on the user-provided resolution, the data is resampled on the server-side based on all the available data sources. Py3DEP returns the requests as xarray dataset…”

Thrilled to have been included on this paper led by Niamh Cahill. We propose a #Bayesian time series model for catchment scale #hydroclimate reconstructions. The paper makes use of the Palaeowise database of Australasian #climate proxy data (the first paper to use the database 🙌) https://onlinelibrary.wiley.com/doi/10.1002/env.2786

I'm very happy that this paper that Ulf Büntgen and I wrote together has finally come out. Using annually resolved #hydroclimate data we found that central Europe experienced increasingly dry summers from the 420 to the 450s CE (and beyond). This coincided with some of the most devastating raids by #Huns on #Roman territory. We argue that Huns used raiding as a buffering strategy to mitigate against dry summers which made it harder for them to pasture their herds. https://www.cam.ac.uk/research/news/drought-encouraged-attilas-huns-to-attack-the-roman-empire-tree-rings-suggest
