Mine is that legislation like Prop 12 and eliminating key CWA exemptions is the best path forward for climate action via dietary shifts

please do! currently wrapping up a section for CCI contrasting ag easements as privatized conservation with public models, I love seeing what other folks are cooking up!

It's a classic win win where cows get grass and meadowlarks get something that's not corn or subdivisions, but biodiversity, land, climate (not just methane, but also nitrous oxide) still suffers.

Most of our most ecologically significant "protected" grasslands are in the production game, and they are DYING, at least compared to the few that aren't. But yeah, conventional corn is worse.

I feel like the newsletter going around might be understating the extent to which the last ~7 years of left climate politics already *was* a pivot to the material needs of working people, and away from a more crunchy 'save the planet' for the planet's own sake.

we will brand our political enemies as our ignorant foils: Know Nothings. While we are Wide Awake and aware, those who remain sleeping and with their heads in the sand can only seem to utter the same trite phrases, and refuse to engage with our attempts at dialogue.

Statistical Identification of Nitrous Oxide Hot Moments and Their Significance Across Global Agroecosystems
The frequency and magnitude of N2O hot moments within agricultural data sets are highly variable Median absolute deviation and minimum covariance determinant can accurately identify hot moments a...

For the first time, this paper provides specificity to the global outsized impact of N2O hot moments, and provides a concrete path toward applying quantitative methods in their investigation. We hope these findings will be a valuable stepping stone toward mitigating N2O from agricultural soils.

The 2nd goal of this paper was of broader interest: just how often to these hot moment events occur, and what is their overall contribution to cropland agriculture's global climate impact? We estimate that hot moments occur about 50 days of the year (14%), but contribute >60% of annual N2O emissions

As data scientists know, having reliable data labels is of the highest importance to building quality models. By using the statistical anomaly detection methods we recommend, researchers will be able to produce accurate data labels for N2O "hot moments" and "background emissions" nearly instantly.
