These papers look amazing

List illustrating the amazing things NCAR could do

Activists capturing and burning methane at an abandoned Colorado coal mine as a “macro solution” for the climate The methane destruction project above Paonia could be a global model for reducing emissions of a potent greenhouse gas

@audenschendler.bsky.social is this you?

This is really cool. I wonder how many other opportunities there are out there like this.

How can we improve the action rate? What will it take?

Which are the right firms to take on this challenge?

What will it take for them to do it?

How do we go from listing opportunities, to converting them into wins?

This was a great excuse to play with SciPy for the first time. scipy.ndimage makes it trivial. I almost feel bad for making it so easy but I'm glad I got to play with a powerful new library.
I just completed "Printing Department"- Day 4 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/4

This one I kinda brute-forced, and after looking at the progress output, I realized you can just calculate the high and low IDs, and simply figure the sum as count*(high+low)/2

round 2 took a while, I kept thinking there must be an elegant way of doing it

The Quick and Shameful Death of Biden’s Biggest Policy It was far too easy for Republicans to kill the Inflation Reduction Act. Where did those who crafted it go wrong?

"The IRA’s survival was premised on the logic that a loose alignment of corporations would support climate policies in exchange for subsidies and convince Republicans to get on their side. That didn’t work"

#qgis plugins site is giving Cloudflare bad gateway error. known issue?

I figure insurance companies will have more accurate forecasting of the impacts of global warming than most, because 1) they have high quality trend data, and 2) they have skin in the game.

Look up grid-forming inverters.

Update on OpenAI Stargate Shackelford (Vantage): Vantage started turning dirt August 7 and are humming right along. Here's the site as of this week.

We’ve unpacked the research, gathered the data, and synthesized the results in a new white paper reviewing Climate TRACE findings from the #emissions reduction roadmap tool.

Read it here: media.climatetrace.org/Climate_TRAC...

The first book sold ~15M copies in the US, so maybe 5% of Americans read it? Yes, surprisingly popular relative to other books perhaps, but still tough to extrapolate to the US as a whole

My intuition is that high robotaxi adoption would want to trade parking spots for road area

Instead of being parked in my driveway/garage, the car is now empty and waiting for (maybe heading to, maybe not) the next pickup

Would be very interesting to model it

Editorial nit: can you please call it ML instead of AI?

On the chart, positive wind speed = westerly? So going to zero, or negative, is a cessation or reversal of direction?

Looks like they’re using some pretty significant waste heat to pre-heat their refrigerant - and they’re using H2O as the refrigerant 🤔 I hadn’t seen H2O as a refrigerant before

This industrial heat pump is cheaper to run than a boiler. Yes,… Skyven Technologies is making clean steam in a cost-effective way. The tech could boost efforts to decarbonize heavy industry.

Skyven Technologies’ industrial heat pump is cheaper to run than a gas boiler. Here’s how the company is easing customers into making the switch.

Interesting…

There seems to be a lot of interest in managing methane emissions. I wish there was a good overview of the impact that these offerings are making

My first thought is, how did they get the data needed to do this analysis? Because I want to do this analysis

I’ll read the paper tomorrow

Well researched. I’m impressed.

from an engineering perspective, it is "intentionally" wasted: systems are designed to reject it. think fans and radiators, cooling towers. they can't let it build up, systems would break. and the owner isn't funding the systems to otherwise use it.

2/3rds of primary energy usage is wasted - just straight dissipated as heat to the environment. 2023 data from LLNL. flowcharts.llnl.gov/commodities/...

wow this is awesome! Thank you

ADs can also cause more atmospheric methane release.
In the ADs, production declines the longer the feedstock is in. Operators rotate the feedstock, which then finishes fermenting outdoors. This late-stage release can be substantial.

What a great chart. The numbers are dated since it's from 2012, but the concept stands: electrical energy is far more efficiently turned into useful work than thermal.

The chart data is from 2012, which is why there's so much coal and so little solar. Here's a cleaner version.
