This is important - as I think this basic point is amazingly often missed in media: the world just keeps getting hotter, and extremes more extreme, until we reach net-zero.

Can't @BBCnews just say "is essential" "Reaching net zero carbon dioxide emissions globally is widely seen as essential to limit further warming." It's not like anyone is suggesting stabilising global temperature via continually increasing reflection of sunlight. www.bbc.co.uk/news/article...

Question: How sensitive are Sahelian mesoscale convective systems to cold-pool suppression? Simple A: Many aspects not as sensitive as some might think Longer A: See Ben's great new paper below rmets.onlinelibrary.wiley.com/doi/10.1002/...

Good to see @bbcnews.bsky.social joining up the chance of >40 DegC, and the forecast hot weather this weekend i.e. using current weather to communicate future risks. They don't always do that, but have here. (Still a "Yay Sunshine" photo of course :-) ) www.bbc.co.uk/news/article...

More important papers in @rmets.org Weather rmets.onlinelibrary.wiley.com/doi/10.1002/... We talk about the "long-tail" of climate risk. Pretty sure Weather has a "long-tail" of highly cited papers.

www.pnas.org/doi/10.1073/... Climate science needs to far more communication of "what could happen" rather than "what we are 99% certain will happen". Challenging, given scope for attacks from anti-climate-science elements in the media.

I know there's a lot happening in the world right now, but I can't find any news reporting at all of this major new study published in Science. Where's the #climate coverage?! "We therefore need to cut GHG emissions even further to have a chance of keeping global warming below 2 degrees"

Paraphrasing, Current targets accept large amounts of largely unrecognised risk. This includes risk of triggering tipping points where thresholds, once crossed, may be irreversible & limit our ability to control climate change. There is currently no realistic plan in place to avoid this scenario.

How sensitive are Sahelian Mesoscale Convective Systems to cold pool suppression? You might think "very". But switching off cold pools doesn't affect diurnal MCS counts, & the reduction of MCS speeds is caused by an AEJ slow-down. Now accepted in QJRMS. essopenarchive.org/users/779964...

But still only way to stop world getting hotter and hotter. So harder, but still easy. But that would ruin the headline... (And even torygraph have someone saying it "makes sense" in the small print.) www.telegraph.co.uk/business/202...

Politicians tell you that airport expansion will protect the typical family's annual holiday. But the majority of flights are taken by the well-off. Airport expansion will simply enable rich people to fly more. Sign the petition against airport expansion: petition.parliament.uk/petitions/71...

I’ve just been to Parliament with @chrisgpackham.bsky.social Sir David King and over 100 scientists to demand politics listens to science on the climate and ecological emergency. @sciencetopolitics.bsky.social

The fact that the shadow energy minister claims there is disagreement about the need to get to net zero is why scientists are rallying outside Parliament today #BringSciencetoPolitics @dremilygrossman.bsky.social @chrisgpackham.bsky.social www.theguardian.com/politics/202...

Great speeches by expert scientists, @chrisgpackham.bsky.social and Sir David King, the former UK chief scientific advisor. Politics must act on facts. This is especially important when it comes to the #climatecrisis. #bringsciencetopolitics

Ukraine, India-Pakistan, Gaza, Starmer on migration - it will be hard for this to cut through, but climate drives war & migration. As a USA military report says just "[Sea level rise] will displace tens (if not hundreds) of millions of people, creating massive, enduring instability”

A dangerous new stage - denying reality and science. It's not hard - the world carries on getting hotter until we reach net-zero. This increases extremes. Warming >1.5 has greatly increased chances of catastrophic outcomes.

Did you know that Ministers had an estimated 104 meetings with fossil companies over the first 3 months of the Labour Government? Can you imagine if half were with scientists instead? How much urgency politicians would feel? If you think science in politics is important please join us tomorrow 👇
