“…past predictions of global warming have proved largely correct. To persist with scepticism is immoral and stupid. Even a free-market fanatic cannot deny that environmental externalities are a form of market failure. Climate is the biggest externality of all.”

By not being at the bad place, y’all are missing this absolute banger of a thread from @volts.wtf. Like him, I don’t care who is the Democratic nominee.

Read this great thread below. We can build a climate community on Bluesky. Here’s a starter pack for folks to follow some people who work on climate. go.bsky.app/Aa1sErQ

Yesterday, I shared this same Canada Day thread on Bluesky, Threads, and X. Here's what I found. 🧵

There's a Department for Leveling Up in the UK. Are they in charge of video games?

Say what you will about the UK, but the quick transition of power and the lack of election denial are refreshing to see.

It was nice meeting @ayeshatandon.bsky.social and @orladwyer.bsky.social at the #NegativeCO2Conference in Oxford. Here's their write-up for @carbonbrief.org. If we have robust MRV, including quantification of uncertainties, marine CDR could play an important role. www.carbonbrief.org/...#NegativeCO2Conference@ayeshatandon.bsky.social and @orladwyer.bsky.social at the #NegativeCO2Conference in Oxford.

A golf cart is sufficient for most people in a city.

Behold $1300 socks. It's not fashionable to talk about consuming less as a climate solution because our economy is based on selling us crap that no one needs.

These geniuses think releasing 40+ billion tonnes of CO₂ a year to the atmosphere does nothing but that chemtrails are real and cloud seeding is what's causing extreme weather events.

Google emits 14.3 million tonnes of CO₂ every year? That’s nothing 14,300 Orca direct air capture facilities can’t fix.

What is this chicane(ry)?

Something something and find out.

With #Beryl barreling across the Caribbean as the earliest cat. 5 on record, let’s remember that things are just going to get worse as we continue to consume nearly 100 million barrels of oil every day.

We’re making a lot of plastic. In the nearly 70 years between 1950 and 2019, we produced a total of ~9.5 billion tonnes of plastic. But that's equivalent in weight to the amount of CO₂ we emitted to the atmosphere during the first three months of 2024.

I see this all the time. 🙄

This is why atmospheric CO₂ is increasing.
