Net-zero CO₂ by 2050 is possible if:

-8,500 coal plants stop burning coal.
-we stop heating homes.
-we stop driving the 1.4 billion cars in the world.
-planes stop flying 100,000 times a day.
-we stop eating tens of billions of animals per year.
-we stop shipping stuff.

Land ecosystems usually remove about a quarter of our annual CO2 emissions from the atmosphere but extreme weather in 2023 caused them to emit almost the same amount. https://t.co/SK3H8nQgyM

Datacentres in Ireland now use more electricity than all the homes. More power than the people of Ireland.. That is wild.

New data shows there are nearly 418,000 flights scheduled between the US and Europe from April to October, 7% higher than the record set last year. https://t.co/qSFE8Edept

@TheEconomist It would be easy to say that rubber-stamping is a bug of fallible humans using the system. It's more accurate to say it's a feature of the system. Irresponsibility is an affordance. The system enables the de facto circumvention of war's rules and norms https://t.co/YqJYa6RnS3

Can't get over that there's been a *68%* increase *in one year* in the number of people who don't have enough food to *3.7 million* people and it's not anywhere near the biggest news story.

“Where Adam Smith and Karl Marx found common ground was in the idea that everyone’s interests are aligned against landlords: they are an economic deadweight.”

Take 2 minutes to watch this. It’s one of the best interviews I’ve seen so far on the #DoctorsStrike. Thank you @DrHilaryJones.

[John Taylor @CoppiceJT]

Why does CO2 have such a big impact on the warmth of our planet when it is only 0.04% of our atmosphere? Because heat radiation IGNORES 99.5% of other gases so they have zero heating effect. CO2 is more like 75% of global warming gases and we have doubled it.

[Roland Pease @PeaseRoland]

Nothing like a morning's discussion on reaching net zero "by 2050" to make you wish for better maths education, all round, including how stuff accumulates over time. Getting there is not the point, what matters is how you get there.

[Tony Juniper @TonyJuniper]

Science is very clear. It’s not net zero in 2050 that must be the headline goal, but cutting emissions before then, including 50% cut by 2030. Delaying action deepens peril for our children & grandchildren. Think Libya, Greece, mass migration & all the rest, & on a massive scale.

[Hannah Ritchie @_HannahRitchie]

The aspect of climate change I'm most worried about is its impacts on agriculture and food security.

Multiple risks: direct heat stress, plus drought and floods.

The impact of last year's floods in Pakistan provides one example.

[Simon Oldridge @SiOldridge]

A 🧵on why UK emissions targets are far from sufficient for 1.5°C, or anything close. The media is focused on the Delivery Gap, but we really need to talk about the #AmbitionGap whilst there's still time to close it. 1/
