Happy birthday to the heatwave of 1976 which began today 50 years ago, peaking at 35.9°C. If a comparable heatwave happened in the current climate it would be 3-4°C hotter, peaking at 38-39°C. And the actual forecast is for temperatures of 38-39°C in the next few days with a red heatwave warning.

Today is #CleanAirDay, a great day to watch our new @granthamicl.bsky.social mini-documentary, The Fight to Clean Up London's Air. We meet Londoners affected by #AirPollution and find out how ambitious policy action informed by robust science is making a real difference. 👇 youtu.be/Adb5VgEW5UQ?...

This Inside Story on #AirPollution from @granthamicl.bsky.social is well worth a watch. The film features our volunteer Beth, who has a young child with lung problems, speaking about the impact on her family. "I can't go to work as a doctor, because my own child is impacted by the air quality".

Hard to believe I’m even writing this. Meteorological summer hasn’t even begun, yet Paris, France has already logged more days above 32°C than its annual average.

🌡️ This week’s heatwave highlights the urgency of reaching #NetZero as quickly as possible. In this excerpt from our recent film on the UK's climate target, Emeritus Professor Joanna Haigh explains that until we stopping adding greenhouse gasses to the atmosphere, climate impacts will worsen.

⚠️ Weather stations in London today recorded highs of 35.1°C, a new May record for the UK. Such extreme heat represents a serious threat to health. Modelling by @gkonstantinoudis.bsky.social estimates that we could see 250+ additional deaths during this heatwave in England and Wales. 🧵[1/6]

Looks like one of those terrifying 2050 #climate projection graphics, but no, that’s a short-term forecast for France until… May 29th.

34.8ºC at Kew Gardens breaks its May AND June records by OVER 4ºC for its May record set in 1922 and by 0.2ºC for its June record set in 1976. Unprecedented heat for the UK in late May, and likely to be bettered tomorrow. A rounded 35ºC temperature should not happen in May.

Europe is the world’s fastest-warming continent. We’ve seen record heatwaves from the Mediterranean to the Arctic, while glaciers have been shrinking and snow cover melting. The evidence is unequivocal: climate change is not a ‘future’ threat. It is our present reality. ⬇️

Congratulations, @frediotto.bsky.social 👏

Achieving UK’s net zero target by 2050 will cost less than a single oil shock and bring health and economic benefits while insulating the country against future costs, says CCC: www.theguardian.com/environment/...

The Antarctic Peninsula faces “substantial and irreparable damage” if global warming exceeds 2°C, polar scientists have warned today 🧵

When it rains, it now rains more. For those experiencing the flooding in south-west England, it is worth remembering that rainfall in winter has increased by about 25% overall. And, the rainfall has also become more intense: when it rains, it now rains more, increasing the risk of flooding.

“The national investment will largely be focused on cycle highways connecting rural villages and suburban areas with metropolitan centres, providing access to jobs, healthcare and education.” Imagine how transformative this approach would be in Ireland. #speirgorm #spéirgorm

What is the current state of climate action? What do latest country pledges add up to? And how much global warming are we in for? 🌍🌡️ 🔥 For the 16th year in a row, we publish the @unep.org #emissionsgap report. As usual, I looked the assessment of the global gap and its global warming implications.

“There is a question that hovers over Irish politics: what will the parties of power do when they start to panic about losing it? Last week, after their joint debacle in the presidential election, we got the grim answer: turn on immigrants.” - @fotoole.bsky.social

An extraordinary omission. Yes, policy is the domain of Gov, but climate is one area where a President, limited though their powers may be, could actually play a significant role, e.g. by mobilising community action and lifting the voices of people affected. 👏 @caugustenborg.bsky.social et al.

This is truly terrifying. Thinking of the Jamaican people tonight. #ClimateCrisis

Ice-free conditions continue in the Barents Sea region of the #Arctic Ocean. This is one area that has observed some of the largest losses of ice over the last few decades... compare the older years (dark/purple lines) to today! Map of this region: zacklabe.files.wordpress.com/2022/08/b203...

🔥 The never-ending narrative… This week, I’ve once again heard prominent climate researchers dismiss individual action as either irrelevant or a distraction instigated by the fossil fuel industry. Here’s a 🧵 on why this argument frustrates me to no end and why I think it misses the bigger picture.

OUT NOW: we revisit the pivotal moment when science, institutions and politics aligned to deliver the UK’s #NetZero target. At a time of political divergence, the evidence for #ClimateAction remains clear. Evidence-based #ClimatePolicy is more relevant than ever. @granthamicl.bsky.social

What happens when science meets politics? Today at @granthamicl.bsky.social, we're kicking off a new series of YouTube docs on that topic! Very pleased to share the first film, exploring how and why, in 2019, #NetZero became law and why the target remains critical today. 👇 youtu.be/Czunu-RkkeY?...

Delighted to share that Dr Gro Harlem Brundland – first woman PM of Norway, former DG of the WHO, founding member of the Elders, and sustainable development pioneer – will give this year's @granthamicl.bsky.social Annual Lecture. Join us in London on 29 October: www.imperial.ac.uk/events/19827...

Human-induced climate change drove extreme temperatures across Europe this summer. New work from @granthamicl.bsky.social and @lshtm.bsky.social reveals how thousands of people lost their lives as a result.

This from the climate minister? How grim. O’Brien either has his head in the clouds or is being intentionally misleading. Sustainable Aviation Fuels made up 0.3% of jet fuel last year; they're far too expensive and difficult to scale to play any significant role in the foreseeable future.

Historic heatwave unfolding in France. Bordeaux just observed its hottest day on record with a provisional 41.6°C (107°F) — data since 1920. Red level extreme heat warnings are in force for the south of the country. Sadly, this heatwave is far from over...

In a new piece for @granthamicl.bsky.social, @frediotto.bsky.social and I unpack the significance of the ICJ’s landmark advisory opinion. We reflect on how it reshapes the legal framing of climate action and what it means for states’ obligations going forward.

Three key takeaways: - Fossil fuel subsidies and licensing can now constitute internationally wrongful acts - The 1.5°C limit is no longer aspirational - it's a legal obligation - States cannot hide behind "concurrent causes" to avoid climate reparations 2/5

Good news is somewhat of a rarity in the climate space, so it's genuinely uplifting to see how advances in climate science are making it possible to hold big emitters to account in the courts. Great new piece on @granthamicl.bsky.social's climate litigation work by @chloefarand.bsky.social 👇

Excellent article by fellow sociologist @ericklinenberg.bsky.social. "Heat is a silent and invisible killer. It usually fails to generate the kind of spectacular imagery that lands weather on prime-time television or a newspaper’s front page." Gift link: www.nytimes.com/2024/09/07/o...

“The climate crisis isn’t tomorrow’s problem, it’s today’s, and its impacts are a broad-spectrum enshittification”. @zoesqwilliams.bsky.social hits the nail on the head in this piece referencing the @granthamicl.bsky.social - @lshtm.bsky.social heatwave study. 👉 www.imperial.ac.uk/grantham/pub...

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👇🏽

What becomes of the 1.5°C goal now that global warming is approaching that level?🌍🔥🌡️ In a new @science.org Policy Forum we explain how the 1.5°C goal remains a critical legal & ethical benchmark, even as the world nears and may soon exceed 1.5°C of global warming🧵1/ www.science.org/doi/10.1126/...
