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/...

More grim news about the West's snow drought:

🛰️ Lowest Feb. 1 snow cover in the satellite record (since 2001)

📉 Record-low Feb. 1 statewide snowpack in Oregon, Colorado, and Utah

Scientists have long relied on tree rings to learn about solar storms.

A Tansley review published this week shows that trees don’t all record this carbon in the same way. Understanding those differences is key to interpreting Earth’s history of space weather.

Back in 2021, I was trying to make "SUP" dendro a thing for us wetland/coastal investigators. We hypothesize this pond was created by a fault scarp ~200 years ago, drowning the cedars, and changing the landscape of Bainbridge Island, WA! doi.org/10.1130/B383... #DendroDating #TreeHistory

Great piece in AZ Water Agenda explaining options in draft EIS for managing Colo River water in drier future. Though I suspect future hydrology will be even worse than pictured, this may be drastic enough to finally get the attention of people here in AZ! azwateragenda.beehiiv.com/p/the-cost-o...
The cost of inaction
The feds outlined their plans if states don’t reach a deal on Colorado River water. It’s a lot of bad options.

Anybody know why there are no P monticola (western white pine) data on the ITRDB? There are some older studies (doi.org/10.2307/1934...). Are they just mixed up with sugar pine?

You probably heard the US admin is threatening to break up the National Center for Atmospheric Research: but did you know they already froze funding for the 9 regional Climate Science Adaptation Centers? From tracking invasives to helping tribes with drought, here's why the CASCs matter ⬇️

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.

The megadrought currently sucking the Southwest dry is having far-reaching impacts on wildlife, especially migratory birds. The elegant trogon is one of them. With arid conditions intensifying, the birds are producing few young, leading to population declines that worry researchers. 🌎
