We've heard a lot recently about the global #foodcrisis. Most coverage focuses on Russia's invasion, blockade of the Black Sea preventing Ukrainian grains & cooking oil exports, high gas prices cutting fertiliser production and sanctions further limiting Russian exports. But...🧵

[Chris Vernon @clv101]

@aeberman12 Consumption can only exceed production for so long... how much longer?

@IvorPowell40 @DaveThroup @MetJam_ And it *will* be under water with a metre of sea level rise.

[Chris Vernon @clv101]

@IvorPowell40 @DaveThroup @MetJam_ It says that if we don't reverse the warming trend by 2000, nations could be lost. We didn't, so they likely will. It *obviously* takes many decades, likely well over a century to actually melt enough ice to see +2m, but it's now gotten so warm that is inevitable.

[Chris Vernon @clv101]

@IvorPowell40 @DaveThroup @MetJam_ No, that's not what it says! 🤯

[Chris Vernon @clv101]

@IvorPowell40 @DaveThroup @MetJam_ With average elevations no more than 2m, these four nations are likely to be lost due to sea level rise, because we didn't reverse the warming trend by 2000: Maldives, 1.5 meters
Tuvalu 1.8 meters
Kiribati 2 meters
Marshall Islands 2 meters

[Chris Vernon @clv101]

@IvorPowell40 @DaveThroup @MetJam_ Seeing as global warming trend was not reversed by 2000, in fact it continued, I expect the the official will be proved right and entire nations could indeed be wiped of the face of the Earth by rising sea levels. It's amazing we knew the risk ~40 years ago yet continued anyway.

[Chris Vernon @clv101]

@1000Frolly @rkhargreaves @ChrisTu33799970 A bigger challenge is to explain how increasing CO2 concentration by over 50% didn't cause temperatures to rise. What prevented the rise? ...and it's a bit of conincidence that even as some other process prevented the rise from CO2, yet another process gave us a rise anyway!

@FarmingUK The global farming community should be pushing government hard for action on climate.

[Dave Throup @DaveThroup]

These are the sort of graphs we’re getting used to seeing.

Temperatures not just way above previous time of year records but challenging all time heat records.

Ridiculous when we’re not even reached Summer yet.

[Daniel Swain @Weather_West]

I've got to say that I'm really disappointed in the recent discourse surrounding the RCP8.5 scenario. The lack of context and understanding is something I expected from the usual suspects, but it's frustrating to see such bad takes from people and outlets who should know better.

[Brian Krassenstein @krassenstein]

HOLY CRAP Trump actually accomplished a miracle. Here is what he got out of Iran:

- Reduce its stockpile of enriched uranium by about 98%

- Limit uranium enrichment to 3.67% purity (far below weapons-grade)

- Cut the number of installed centrifuges by roughly two-thirds

- Only enrich uranium at one declared site (Natanz)

- Stop enrichment activities at Fordow and convert it into a research facility

- Redesign the Arak heavy-water reactor so it could not easily produce weapons-grade plutonium

- Ship out or dilute excess enriched uranium
Allow extensive inspections by the International Atomic Energy Agency (IAEA)
Permit continuous monitoring of nuclear facilities and supply chains

- Accept “snap” inspections under expanded monitoring rules

- Avoid building new heavy-water reactors for years

- Stay within strict limits on uranium stockpile size and centrifuge development for set periods ranging from 10–25 years

Ooops, sorry!

That was the JCPOA that Obama signed with Iran, only to have him tear it up, kill 140 kids, get hundreds of Americans injured, 13 killed, and gas prices to surge 50%.

@ClaireCoutinho @aDissentient What's insane is that we're lifting sanctions on Russia *before* taking any domestic demand side action. We need to be rationing diesel and jet fuel asap, I'm sure you and your party will fully support the Government's rationing plans in the summer.

[Ed Conway @EdConwaySky]

Remember how last Oct the UK said it was going to ban oil products (eg diesel/kerosene) made from oil that originally came from Russia (eg refined in India etc)?
Well now, in the face of the current shortage, that sanction has now been canned👇

[Chris Vernon @clv101]

@cadman_william @GarethDennis Of course he's a purist, many of us are, it's exactly why the broadly defined left have such a hard time winning. Reform is likely to firm the UK government in '29 precisely because the broad left - which certainly includes Labour - can't get their sh*t together.

[Caroline Lucas @CarolineLucas]

I hope this isn’t true. There are times when it’s more important to put country before party. This is one of them. Burnham’s longstanding commitment to a fairer voting system could transform our democracy & counter dire threat of a Reform UK government https://t.co/PNfl5GnB0X

[Chris Vernon @clv101]

@nomatestype @joshsimonsmp @TheGreenParty @LibDems Politics is relative. Even today's Labour (a future party under Burnham would be more so) is to the left of Reform. My hunch is that most Green and LibDem voters would prefer Burnham's Labour to form next government vs Farage's Reform.

@ammacj @joshsimonsmp @TheGreenParty @LibDems No, that's not what I wrote at all! 😅
