Important reminder here that the US is not the only place where fossil fuel interests are pushing back hard against climate science and clean energy 👇

Saint Vice @savic.bsky.social · 2h

BBC decided to cancel a podcast on heat pumps deeming the topic "controversial" because it presented that the technology could contribute to net zero reducing carbon emmissions.

In 2025 an anti-science posture is not only valid, but required in any debate to be considered "balanced" 😬

Quasi monthly update of the monthly climate dashboard

The first September updates are starting to come in. Globally another very warm month.

www.jkclimate.fr/MonthlyDashb...

Graph showing monthly global mean temperature anomalies from 1850 (in varying shades of yellow, green then dark blue with colours getting darker over time) to 2025 (shown in red). Data are from six data sets: HadCRUT5, NOAAGlobalTemp v5, GISTEMP, Berkeley Earth, JRA-3Q and ERA5. The latest month shown is September 2025.

Graph showing the ranking for monthly global mean temperature from six data sets between February 2023 and September 2025. Rankings are shown as coloured squares. Red is warmest on record (for that month and dataset), orange is second warmest, deep yellow (a beautiful shade that I want to call cadmium yellow but it's not toxic) means a top five month and pale yellow (the colour of sun-faded straw) is top ten. Nothing is outside that range. Every single warmest month in all datasets happened since July 2023.

Fossil Fuel executive says the quiet part out loud: "supply leads demand. You put more supply on the market and more demand gets created".

Ketan Joshi @ketanjoshi.co · 1d

Please enjoy this executive at one of America's biggest gas companies openly admitting that expanding supply leads to increased demand for fossil fuels

He is not wrong: frantic expansion of fossil fuel supply worsens climate change. Tax it, cut subsidies, wind it down

Will Jordan, chief legal and policy officer at EQT, a leading US gas producer, also thought that any glut would be temporary, and said US demand was also rising on the boom in power-hungry artificial intelligence data centres.

💯 %. The climate crisis is a policy failure, not something that can be solved by individual actions. Putting the onus on consumers when the system is built to benefit wealthy corporate executives and investors is just the wrong place to focus. sure do what you can, but demand and vote for change

Alex Barron @alexrbarron.bsky.social · 20h

This post buries the lede: "Push for what you can't control alone. Vote for leaders who support climate-smart investments; demand action from those already in power; sign petitions; and join collective campaigns that drive change at scale."

The fossil fuel industry is raiding the infrastructure of the US government.

Are we allowed to be opposed to fossil fuels yet, or is that not enough of a Pragmatic Realist Climate Reset Agenda

Trump Admin Has Hired 100+ ‘Fossil Fuel Insiders’ to Fill Top Energy, Environmental Agency Roles
One of them described her job as offering “concierge, white-glove service” to oil, gas, and coal companies seeking permits from regulators.
Stephen Prager
Oct 08, 2025

A top energy adviser to President Donald Trump admitted in an August interview that the administration is offering “concierge, white-glove service” to fossil fuel companies while blocking and defunding clean energy projects.

The comments, reported Tuesday by the Washington Post, came from Brittany Kelm, a senior policy adviser for Trump’s National Energy Dominance Council (NEDC), which was established within the Department of the Interior in February.

Getting faster at cooking something over time is a learning rate.

This can be decomposed into parts:

Talking about 300x more miles per acre on Solar + EV than ethanol + ICE… is my love language.

Calculations vary slightly, but the conclusion is the same: solar is better on all measurable metrics than corn ethanol. No matter how “prime” the farmland is.

Kevin J. CREATURE @kevinjkircher.com · 17h

Over 40% of corn grown in Indiana is used to make ethanol that cars burn. One acre of corn yields about 16,500 vehicle-miles per year of ethanol, which sounds high until you realize that one acre of solar yields about 2,700,000 vehicle-miles per year: 16,000% more driving for a given plot of land.

This is a big deal because public space only works if the public shows up, and having food trucks and other types of vendors at parks will encourage people not only to visit, but to stay there and hang out a while.
