We had farmers, unions, scientists and environmental experts around the same table – they all agree the EU's farming system needs urgent change But the EU Commission just plans more of the same: eat away at nature, reward land-owners, put small farms out of business & hollow out rural communities

1. A few years ago, people like me were widely attacked in the media for “declinism”. How could we fail to see that we were heading into a capitalist utopia, in which everything would keep getting better? This is a thread about what we could see that our critics could not. 🧵

New poll shows support for lynx reintroduction in Scotland rises to 61% for and only 13% against! John Swinney SNP you are out of step!

This is worth reading and sharing, no matter what side of the border you’re on — Canada’s Other Anti-Trump Weapon: Fighting Corruption. “Beyond waging a tariff war [aka fighting back against the insane trade war Trump started], target the US president’s dependence on dirty money.” Via @thetyee.ca

The Relentless Rise of Electric Truck Sales in China Almost 80,000 zero-emission medium and heavy-duty vehicles were sold in China last year, more than double compared to '23 ⚡️⚡️⚡️ "more than 25 times the number sold three years prior." #alwaysbecharging

Global sales of combustion engine cars have peaked

Reintroducing wolves to Scottish Highlands could help expand native woodlands, says study - Researchers say the animals could keep red deer numbers under control, leading to storage of 1m tonnes of CO2 www.theguardian.com/environment/...

German electricity generation mix, 1990-2024. After the nuclear exit, are they using more coal*? No, less. More natural gas then? No, less. Could they have used even less coal and gas if they hadn't shut down nuclear? Yes. *) Lignite = brown coal. Graph: www.cleanenergywire.org/factsheets/g...

At first glance, a quintessentially beautiful Irish landscape. But in reality, it's a deadzone. The graveyard of a once species-rich Atlantic rainforest wonderland, smothered under sheep and, in the distance, sitka. We are, however, waking to just how much has been stolen from us.

There's an unelected multibillionaire now running amok in #Washington and US farmers, small towns and Main Street businesses will suffer as a result.

“As pickups transitioned from workhorses to lifestyle vehicles, their design shifted accordingly: Cabs expanded for more passengers, while beds shrank. The first generation of F-150s was 36% cab & 64% bed by length. By 2021, the ratio flipped, with 63% cab & 37% bed.” www.axios.com/2023/01/23/p...

“At the root of the problem is the philosophy that the way to cater to motor vehicles was simply to build bigger, wider roads…the roads encouraged extra driving, which in turn filled up the roads, causing congestion at least as severe as that they were meant to relieve.” Via @financialtimes.com

Measures like weight-based taxation and eco-friendly tyre innovations would not only reduce tyre pollution but also pave the way for more sustainable transportation systems

Farming is a tough job & it's only getting tougher as our climate changes. But what if there was a better way to feed 10 billion people, one that didn't involve hardship, slaughtering animals or wrecking the environment? There is, as @georgemonbiot.bsky.social explains.

George Monibot, "We have a Chancellor and. Prime Minister who seem to have no vision at all, except this thing called growth, GDP growth" "GDP should not be used as a measure of national welfare" #BBCQT

Let's make climate great again! Check out this piece by me and @carolinelucas.bsky.social to find out how. https://buff.ly/42Xqut8 #Climate #ClimateNews

Land for peace. Works every time ... 🙄

Richest nations ‘exporting extinction’ with demand for beef, palm oil and timber

“The more we’ve learnt about how to do nuclear power, the more expensive it’s got. That’s the opposite of what usually happens.” Quote from Prof. Bent Flyvbjerg in great piece by FT on why so many nuclear projects get a) delayed and b) are over budget. www.ft.com/content/5e56...

What if society's focus shifted from economic growth to human well-being within the boundaries of what Earth can provide? A team of researchers tackled that question in a new review from the Lancet Planetary Health, and I spoke with the lead author for mongabay.bsky.social‬:

I'm proud to see a Labour PM become the first PM to every get tested for HIV publicly as a part of #HIVTestingWeek. This Govt is aiming to end new HIV transmissions by 2030. Together, we can destigmatise HIV & ensure those with HIV can access the treatment they need.

Big news 📣 National HIV Testing Week kicks off in just under a fortnight! Testing is free, quick, and easy—plus, you can even do it from home.  Find out more at https://buff.ly/4gSqLSl #ITEST #HIVTestingWeek

We need to leave fossil fuels in the ground, if our civilisation is to have a future, so any production cut would be a step in the right direction. #Climate

If, for example, the Chinese state did half of what Musk and Trump are doing to the US federal government, degrading its capacities, undermining its ability to function, destabilising the Union, it would be considered an act of war. These are not patriots. They're an urgent threat to national life.

Re sustainable aviation, #hydrogen is not the answer for aircraft [due to cryogenic storage and low energy density] but SAF/battery powered hybrids and just battery aircraft are.

At last a story about some US Republican politicians who have not been silenced by Trump.

We need to leave fossil fuels in the ground. The World is heading for dangers unseen in the 10,000 years of human civilization, and efforts to make the world more resilient were needed but by themselves could not soften the impact enough.

Genetically engineered #potatoes can produce cow milk #proteins to reduce the need for #cows & thus reduce GHG #emissions, as the #dairy industry is an important driver of such emissions, producing as much as the aviation & shipping industries combined… (1/2) www.zmescience.com/science/news... #GMO

Here are the landfills that could take toxic waste from the L.A. wildfires in the coming weeks — many have not accepted hazardous materials in the past.
