I don’t know who needs to hear this but the CDC is being eviscerated right now. America is not going to have any kind of outbreak response capacity after tonight. Americans’ health data is no longer secure. Say goodbye to federal public health in any capacity. It’s a disaster. We won’t recover.

We could get rid of half of the radiative forcing of climate caused by aviation if we could get airlines to stop making contrails, mostly by flying a few thousand feet higher or lower.

A Stylized Study of the Climate Response to Longwave and Shortwave Forcing at the Altitude of Aviation‐Induced Cirrus

For the same magnitude of LW and SW forcing at the altitude of aviation-induced cirrus, climate sensitivity is larger when the forcing is imposed at high latitudes For the same change in concentr...

Excellent, well-informed new podcast! Like a ship entering a storm, we’re now entering the overshoot - a world above 1.5 degrees C #globalwarming. This requires a whole new mindset,
explored by Laurie Laybourn.

High-level conclusion: the environmental footprint of poplar-derived cellulosic ethanol production is much more sensitive to poplar yield than it is to poplar biomass quality (sugar content).

Similar what we concluded previously for switchgrass— doi.org/10.1021/acss...

Biologically diverse long-term common gardens can provide unique insights into plant controls on biogeochemical cycling, even if they weren't originally designed for it. We're now sampling 300+ other genotypes at this site, to try to resolve the controls and mechanisms affecting soil C & N cycling.

We found:
- surface mineral-associated C stock differences under black cottonwood trees of different genotype.
- soil C associated more strongly with root elemental content than root lignin, N, or aboveground biomass.
- surface soil C stocks diverged by genotype at rates of 1–4 Mg/ha/y.
