You may think watching TV is an innocuous pastime.
And telling people to watch less TV must certainly be one of the most unpopular messages ever.

Nevertheless, people should be aware that the contributions to CO2 emissions (and so to global warming) from internet TV and video are already larger than those from flying.
And while emissions from flying are only set to grow slowly, those from internet TV and video are rising rapidly.

This is all down to more and more people watching more and more TV and video at higher and higher resolutions.
And it is entirely unsustainable.


“We found the mitigation efforts needed to get aviation to a place where it’s compatible with the Paris agreement are enormous,” says Brazzola.

Aviation strongly affects the , not just by emitting CO2. The only viable way forward is to drastically reduce the number of flights.

@walter @lena @devinprater Yeah, sadly, part of the problem is that accessibility tools do little more than the bare minimum. Yet another lovely gift of capitalism where things that don’t generate huge amounts of profit find little investment and love. It’s so sad that the most effective accessibility pitches are those that aim to convince corporations that improvements will lead to higher profits.

🇬🇧 Absolutely preposterous! Yesterday, conservatives, liberals and right-wingers in the EU Parliament made sure that #gas and #nuclear power will be classified as sustainable in the future. #NotMyTaxonomy #Taxonomy

OMG! I'm so excited to announce that through my work at @spritelyinst we've published A Scheme Primer:
Direct link:

This document manages to serve two purposes:
- As a quick skim, it's a reasonable intro to "how to start programming with Scheme with no prior experience". Hey, tutorials are useful!
- But also, in less than 30 pages we manage to compress a TON of computer science ideas in a way that I think is really, really approachable.

The document ends with a code example, and full walkthrough, of a Scheme interpreter written in Scheme... in a mere 30 lines of code! It's like 3/4 of Structure and Interpretation of Computer Programs compressed into a document you could read in an afternoon!

"Noble says that the UK uses in the region of 100,000 cubic metres of peat a year for this purpose, or roughly a ninth of the peat extracted from UK landscapes annually."

I strongly encourage any mathematically minded person to watch this talk and think about what they can contribute.

@EU_Commission I love technology but it will only partially contribute to the solution.

This problem needs social, political & economic courage. We need degrowth, reduction of our exploitation of natural resources & marginalized people, an end to fossil fuel & making climate-unfriendly activity illegal or expensive (especially for big business).

All stuff we could’ve started with decades ago but will now be forced to do in a few short years if we can muster the urgency.

Finally, Li et al is a model study on projecting future changes in extremes, surely observation based studies such as Lorenz et al 2019 Geophys. Res. Let. 46, 8363 would be a better choice (for Europe at least):
"We demonstrate that on average across Europe the number of days with extreme heat and heat stress has more than tripled and hot extremes have warmed by 2.3℃ from 1950–2018."

Refer to the principal source, not the IPCC, it summarizes evidence from the literature. Also, referring to the nearly 2000-page WG1 report is not very helpful.

This is an important message, but the communication is far from clear. The pre-industrial 1 in 50 chance event determines a fixed temperature threshold, it can't get hotter. Surely they mean that the 1/50 pre-industrial event has become more frequent and that 1/50 events have become hotter.

The sentence is from Clarke et al 2022:

They also refer to the . The IPCC in turn refers to Li et al 2021:
