In any discussion of food and farming, unless your solution can be scaled to feed 8 billion people, you shouldn't be taken seriously. Unfortunately, cottagecore fantasies that would feed only the richest consumers, leaving billions to starve, are all too common. www.monbiot.com/2023/10/04/t...

Last week, @ceciliakeating.carbonbrief.org and I attended the first-ever conference on climate "overshoot" in Vienna. Here's our summary of the wide-ranging discussions. (Bearing in mind we were two journalists covering 8 conference themes...!)

Jimmy Fletcher - former St Lucia minister and Paris Agreement architect- is speaking at the @iiasa.ac.at overshoot conference about how breaching climate targets will impact small island states Describes overshoot of 1.5C as "pathway of harm, loss and inequity that no small island state can accept"

Brilliant to work with @wellcometrust.bsky.social on this article which looks at how fungi are learning to adapt to rising temperatures — with serious implications for human health www.carbonbrief.org/guest-post-f...

FACTCHECK: No, North Sea gas is not "four times cleaner" than LNG imports After Kemi Badenoch pledged to extract every last drop from the North Sea, we've been engulfed by waves of long-dead zombie factoids. "Four times cleaner" is one of the silliest. www.carbonbrief.org/factcheck-no...

It seems like an age ago now, but back in 2020 I worked on an op-ed for @businessgreen.bsky.social from @kemibadenochmp.bsky.social where she explicitly backed net zero It states she is "proud" the UK is the "first major economy... to legislate to end its contribution to global warming by 2050"

That's a *chef's kiss* of a community note, though.

Are you or your loved ones worried about solar farms? Have you heard scary things about solar panels turning the countryside into an industrial hellscape? Fear not! We at Carbon Brief have just published the definitive article debunking solar myths ⬇️ interactive.carbonbrief.org/factcheck/so...

The UK has seen widespread drought this summer. But to what extent are UK droughts being impacted by climate change? In a timely piece up on @carbonbrief.org today, @ukceh.bsky.social hydrologists look at whether global warming is making UK droughts worse www.carbonbrief.org/guest-post-i...

🚨 We’ve just updated @carbonbrief.org's factcheck of Trump’s ‘critical’ climate report. 🚨 Huge thanks to all the dozens of climate scientists who have helped us pull together this rebuttal — including the authors of our brand new additions. interactive.carbonbrief.org/doe-factchec...

Since #Brexit, UK now has lower standards than EU in: * protecting nature * water quality * air pollution * methane control * pesticides * chemicals * deforestation supply chains * waste reduction Only on marine protection does UK have a better story to tell www.theguardian.com/politics/202...

So many of these pics are in front of land that has been absolutely razed by farming activities

Truly devastating for Trump's climate report. It just shows once again: if you task a group of "climate skeptics" with a climate report, you get a mass of easily refuted falsehoods, as they simply do not have honest arguments on their side. interactive.carbonbrief.org/doe-factchec...

The EPA cited my paper in their argument against the endangerment finding today. However, their point is completely backwards: my paper actually supports the EPA's 2009 range of 1.8C to 4C warming by 2100. www.nature.com/artic...

NEW: A former Microsoft AI engineer says the company's "AI for sustainability" claims are BS, a distraction from their hyper-polluting AI contracts with oil companies. “From what I saw," he said, "I believe that finding and extracting more oil is one of the biggest use cases of AI today."

Last week, scientists, journalists, policy wonks and campaigners took part in a conference on climate tipping points - from collapsing ice sheets and coral die-off to thawing permafrost to Amazon dieback @carbonbrief.org's full write-up of the event is now out - www.carbonbrief.org/tipping-poin...

At the #tippingpoints conference, @rockymtninst.bsky.social's Laurens Speelman is presenting on the “compounding effects’’ of clean tech adoption He says: “As tech gets better and costs reduce, sectors that were previously thought to be untippable start to become tippable"

At the #tippingpoints conference, @clubofrome.org's Sandrine Dixson-Decleve says the economic system is dictated by “shareholder value” and "no longer responds to the needs of people, planet or prosperity" Without changes to business models and business governance “we will get nowhere”, she says

Dr Patricia Pinho is talking about social tipping points among communities in the Amazon She points to a "direct link between violence to the environment and violence to people" Says this is a "huge problem" impacting the region, where there are 20% more homicides than a UN threshold

@wanderinggaia.bsky.social is speaking at the Exeter #tippingpoints conference She describes social tipping points as "a dramatic change" that tips a place people from "being a place to flee from, rather than a place to stay” This could be due to homes becoming uninsurable, or poor food supply

Not a lot of love for the press at the tipping points conference Rockström says the media is “getting it very wrong, seriously wrong” Dr Carlos Nobre points to a lack of coverage of the impacts of the degradation of topical forests, noting the "tremendous risk of epidemics and pandemics”

Prof Johan Rockström tells the tipping point conference "there are now, scientifically, a list of tipping element systems that fulfil the criteria of being at high likelihood of occurrence and reaching the unacceptably high impact [required to meet] global catastrophic risk criteria."

If extreme weather had a capital, it would be Mumbai. We’ve got it all: floods, sea-level rise, cyclones, heat islands. Mumbaikars are sick of being called resilient and being caught off-guard. But forecasting the monsoon is fraught, more so with climate change. My dispatch for @carbonbrief.org👇🏽

ICYMI from last week - New research looks into the combined effect of global warming and a potential AMOC collapse on northern European temperatures. TL;DR is that winters could get much, much colder (down to -19C in London) while summers cool just a bit. www.carbonbrief.org/ocean-curren...

High warming rate fuels record-breaking weather The longer our measurements, the fewer record-breaking events we should observe. The opposite is the case - many more records and higher record margins I summarise the key takeaways of our ‪@natrevearthenviron.nature.com article in a guest post.

We don’t know how close we are to triggering an Atlantic Ocean circulation #AMOC breakdown - but now we know a lot more about what it would mean for extreme temperatures in Europe. Good @carbonbrief.org piece on a new study just out by the Dutch colleagues! 🌊 www.carbonbrief.org/ocean-curren...

Received this leaflet over the weekend from the PFFA. A bingo list of climate sceptic talking points, including: - world isn't heating - humans thrive in heat - increased co2 is good for plants - net zero to blame for energy costs - boilers cleanest way to heat homes - what about China?

"Tipping points" are "thresholds where a small additional change in global warming will cause [major biophysical systems] to irreversibly shift into a new state." *Cascading* tipping points occur when crossing one threshold triggers another, & so on. We should be extremely scared of these. So...
