Looking for ways to help the battle against global warming. Lifelong nerd, I ❤️ data.
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?
A UN Environment Programme satellite watches for super-emitter events of methane (the main component of natural gas and a fast/potent greenhouse gas) and alerts the people responsible. Out of 3,500+ alerts since 2022, UNEP "documented 25 cases of mitigation action."
That's a 0.7% action rate. 🤦
That's a 0.7% action rate. 🤦
Better data driving action on methane emissions, but more work needed
Nairobi, 22 October 2025 – Government and industry responses to UNEP’s more than 3,500 satellite methane alerts climbed from one to 12 per cent in the past year. Nevertheless, action must accelerate t...

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 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.
New research shows climate risk is already hitting insurance and home values. And that’s only part of the story. Some serious hazards, like saltwater intrusion, often aren’t covered at all -- and aren’t yet priced into housing markets. Column today: susanpcrawford.substack.com/p/new-data-s...

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
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.

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.
Over 2/3 of primary energy is wasted as heat.
The transition isn’t about matching that waste — it’s about outperforming it with efficient clean energy technology.

we have *got* to get methane emissions under control
What you see without an OGI camera vs what you see with an OGI camera.
What you are seeing in a plume of methane and VOCs.
You can see how it is so easy for them to ignore the ongoing systemic methane pollution.

Those complaining about the high rate of electricity in California, are sort of out of touch with reality. High rates *DONT* mean high bills.
Normal people - i.e. not #energysky - don't care about the RATE they pay, but the BILL at the end of the month.
Californians pay less than 40 states.
