AGU has a Congressional email and call script up on NCAR:

Save NCAR from being dismantled today!

The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

I started getting reports of an unseasonal Joshua tree bloom in the last few weeks, and looking over records on @inaturalist.bsky.social it's pretty widespread! So we're putting out the call for folks to record this "bonus bloom" and help us study it 🌿

Weird wet weather has Joshua trees flowering early — or late? Help the Yoder Lab map this “bonus bloom” to understand why

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'.

I had missed this article earlier. An example of what we're losing, in terms of science that could make a difference for people in this time of climate crisis. Just one relatively small research group at one university (my own #NorthernArizonaUniversity). Gift link: www.nytimes.com/2025/10/08/c...

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. 🌎

Despite broad political support, one third of the nation's Climate Adaptation Science Centers will wind down in coming days due to lack of funds.

The Northeast, South Central, and Pacific Islands will be left without actionable science on drought, floods, wildfire, sea level rise and other hazards.

Trump officials shut off funding for climate adaptation centers

A third of the U.S. Geological Survey’s Climate Adaptation Science Centers are expected to drastically wind down and possibly close after Sept. 30.

New paper led by PhD student Elise Pletcher! Forecasts from simple, density-dependent population models are highly transferable to new sites. Adding env. covariates does little to improve prediction in-sample and worsens forecasts out-of-sample. besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Density‐dependent growth and dispersal can accurately forecast near‐term range shifts in a dominant dryland tree species

We found that the inclusion of external drivers such as climate conditions or topography generally did not improve forecast accuracy and that at multidecadal time scales, intrinsic population process....
