AI ads should come with warnings similar to those for pharmaceuticals, e.g., may cause loss of critical thinking, problem solving, and creativity; may contribute to high energy costs, rising temperatures, and depletion of water resources; you may experience threats to democracy with use of AI…

Tree rings form a natural archive, recording fire, drought, insects, saltwater intrusion, and climate year by year. Across the U.S., dendrochronology reveals the secrets trees hold. My latest project in Nature Conservancy Magazine

History in the Rings

A tree’s rings can tell a much deeper story than just the number of years it has lived.

My colleagues Calvin Farris (NPS) and Ellis Margolis (USGS) led a landmark study in paleofire reconstruction. In addition to showing that fire management can restore past fire regimes, the demonstrated methods are a first in dendrochronology. 1/6 esajournals.onlinelibrary.wiley.com/doi/10.1002/...

good piece digging into the DOE's phony climate report, which is "starkly at odds with the vast majority of scientific evidence," explicitly dishonest, and clearly designed to justify otherwise-unjustifiable political goals: www.politico.com/interactives...

Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/...

And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10....

Paleoclimate evidence generally provides the strongest constraint on high ECS.

New paper in ERL led by Feng Wang evaluating gridded daily climate products. Interesting results include: 1) how day-shifting affects the records; 2) Pierce vs Livneh precip data (a surprise!); and 3) differences don’t really matter for tree growth modeling. doi.org/10.1088/1748...

"A federal judge on Friday ruled the Energy Department violated the law when Secretary Chris Wright handpicked five researchers who reject the scientific consensus on climate change to work in secret on a sweeping government report on global warming."

The Pliocene climate was more sensitive than the current climate, suggesting that the upper bound of potential 21st-century warming—an estimate informed by Pliocene warming—should be revised down from 5 °C to 4 °C, according to the authors. In PNAS: https://ow.ly/U5H750Y5yUo
