Every year now, the pre-monsoon heat (the hottest time of year in South Asia with temperatures well over 40°C) starts earlier & lasts longer - due to human-induced climate change - exposing 1billion people to deadly heat. @wwattribution.bsky.social www.worldweatherattribution.org/climate-chan...

NEW: Players and fans face increased heat danger at the 2026 FIFA World Cup, since USA '94. Our results show that from Miami to Kansas City, climate change is increasing the risk of playing the World Cup in much of the northern hemisphere during summer. (1/2)

RAPID ANALYSIS: It would be ‘virtually impossible’ for the record-breaking March heat currently scorching the U.S. West to occur without climate change. We are seeing summer-like temperatures arrive exceptionally early from the Pacific to the Rockies this week. 🧵1/4

We’re excited to announce that @frediotto.bsky.social has been awarded Germany’s highest honour for her groundbreaking work on climate science and extreme weather. The award recognises her pivotal role in revolutionising attribution science: connecting extreme weather events to climate change.

After more than 70 killed in Brazil landslides, scientists at @wwattribution.bsky.social warn deadly downpours will worsen with further warming of the climate. buff.ly/OUV8Wz0

In a rapidly warming world, landslides in high-risk areas are happening sooner rather than later. Making it paramount to reduce exposure & stop the rapid warming. New @wwattribution.bsky.social study on Juiz de Fora landslides www.worldweatherattribution.org/unplanned-ur...

New study: Intense rainfall - like the deluge behind Brazil’s recent fatal landslides - will intensify as the planet continues to warm. Over 70 were killed in the state of Minas Gerais in late February with Juiz de Fora - the worst impacted city - seeing its wettest month on record. 🧵 1/4

NEW STUDY: Winter downpours are getting heavier in parts of Spain, Portugal and Morocco as the region recovers from a month of relentless storms. Between mid-January and mid-February nine named storms brought torrential rain hurricane force winds causing major damage and disruption. 1/5

Patagonian wildfires show how denying climate change & pushing environmental destruction make the reality of climate change much worse. Threatening the destruction of trees that have been alive when the bronze age collapsed. @wwattribution.bsky.social www.worldweatherattribution.org/climate-chan...

Some of world’s oldest trees hit by climate-fuelled wildfires in Patagonia - Some Alerce trees had stood undisturbed for thousands of years, say researchers, but global heating is now supercharging blazes @wwattribution.bsky.social #climatecrisis Story by me www.theguardian.com/world/2026/f...

NEW STUDY: Climate change is fueling deadly fires that threaten some of the world’s oldest living things: the ancient Alerce trees of Patagonia, which can live for over 3,000 years. Our analysis shows that human-induced warming is making weather conditions more conducive to fire. 1/5

💡New Study: Southern Africa was hit by intense rainfall this month. Our analysis has found that downpours in the region are now 40% more intense than they were in pre-industrial times. The resulting floods across Mozambique, South Africa, Zimbabwe, and Eswatini have been catastrophic. 🧵 (1/4)

While Australian heatwaves were some of the very first extreme events attributed to climate change, people still underestimate how much worse they got - killing more people than all other natural hazards combined. New @wwattribution.bsky.social study. www.worldweatherattribution.org/climate-chan...

🚨 NEW STUDY: As Australia prepares for another heatwave, our latest study found the early January heatwave which hit SE Australia was made 5x more likely due to climate change. What was once a relatively rare 1-in-25-year event is now expected about every 5 years. 🧵 1/6

Great to see coverage of our first full @wasitusie.bsky.social study on RTE (and elsewhere). Kudos @clairebergin.bsky.social and Lionel swan as well as met Éireann colleagues and thanks as ever to @wwattribution.bsky.social for the hugely valuable collaboration www.rte.ie/news/ireland...

🚨 Wildfires in Spain & Portugal were made 40x more likely by climate breakdown, says @wwattribution.bsky.social “The sheer size of these fires has been astonishing,” adds CEP’s Clair Barnes (@clairbarnes.bsky.social) 🌍🔥 #ClimateCrisis #Wildfires

⚠️Climate change made the hot, dry and windy weather that fueled the deadly July wildfires in Spain and Portugal 40 times more likely 🧵 📝 ow.ly/SoRo50WPvih

The extremely hot, dry weather conditions that primed Spain and Portugal for this year's catastrophic wildfire season are no longer a rare occurrence thanks to human-caused warming. This probably shouldn't come as a surprise, but if it does, the full study is @wwattribution.bsky.social...

❗ El cambio climático hizo 40 veces más probables y un 30% más intensas las condiciones que alimentaron los incendios de España y Portugal, según un estudio de atribución realizado por el @wwattribution.bsky.social .

🌡️ Scientists from @wwattribution.bsky.social say this summer’s wildfires in Greece, Turkey & Cyprus were 22% more intense & 10x more likely due to climate change. Events that were once 1-in-100-year now happen every 20 years. 🔥 #ClimateCrisis #Wildfires

In an interview at @mongabay.com, @wwattribution.bsky.social researcher and environmental statistician @clairbarnes.bsky.social explains how attribution science, which helps scientists understand climate change’s impact on a particular extreme weather event, works.

One of the strongest, clearest increases in likelihood & intensity, attributable to climate change, I've seen in a complex index like fire weather - the more intense & frequent events in Greece & Türkiye are already outpacing efforts to adapt. www.worldweatherattribution.org/weather-cond...

🔥Climate change made the weather that drove deadly wildfires in Türkiye, Greece and Cyprus 22% more intense. The study, by @wwattribution.bsky.social, examined weather conditions in the months and days leading up to and during the worst blazes in June and July this year 🧵

The wildfires that raged across Greece, Turkey and Cyprus this summer were 22% more intense and 10 times more likely than they would have been in a world without climate change, according to scientists at @wwattribution.bsky.social FREE link via @bloomberg.com www.bloomberg.com/news/article...

One of the best climate science comms jobs around, helping journalists explain how climate change has influenced extreme weather events, working with a top bunch of scientists at @wwattribution.bsky.social including @frediotto.bsky.social. London based, closes 5 Sep

Attributing extreme weather events to #climatechange is tricky But since 2014, the international network of researchers World Weather Attribution has pioneered methods that make it possible My @mongabay.com colleague spoke w/ @wwattribution.bsky.social's @clairbarnes.bsky.social to learn more:

🌍 Leading the charge on climate action @imperialcollegeldn.bsky.social has 11 IPCC AR7 authors - the most of any institution! CEP’s Joeri Rogelj, Friederike Otto, Robin Lamboll & Jarmo Kikstra are shaping the science behind global policy. #IPCC #ClimateAction

In July Fennoscandia was hit by a heatwave similar to one that hit the region in 2018. In just seven years, similar events have become almost twice as likely due to increased global temperatures from 1.1 to 1.3°C. Every fraction of a degree matters! www.worldweatherattribution.org/intense-two-...

“Even if climate change plays a big role in the weather event, what turns weather into a disaster is always strongly shaped by vulnerability and exposure". Read @wwattribution.bsky.social Dr @frediotto.bsky.social's comments for @grist.org on the Texas Floods: grist.org/extreme-weat...

Our Senior Scientist @fahadiii.bsky.social speaks to BBC News about how the fatal floods in Pakistan were made 15% more intense due to climate change. "If you consider that Pakistan's role in total emissions is less than 1%, it's a big case of climate injustice," he says @wwattribution.bsky.social

Climate change made the relentless heatwave in Norway, Sweden and Finland about 2°C hotter and at least ten times more likely. Our latest study was published this morning. “This event should be taken as another reminder that no country is safe from climate change” - @frediotto.bsky.social 🧵

A new @wwattribution.bsky.social study shows climate change made Pakistan’s recent heavy rains 10-15% heavier, fuelling devastating floods that killed 300+ people and destroyed thousands of homes. It’s time to build resilient homes and slash emissions before it’s too late 🌍 #ClimateCrisis #Floods

Yet again, temperatures are pushing past 30°C in parts of the UK. This is the fourth heatwave of the year and climate change is making today's temperatures about 2-4°C hotter, says scientists at @wwattribution.bsky.social 🧵

Heavy monsoon rains have led to more than 300 deaths in Pakistan since late June. Climate change increased the downpours by about 15% 📈 Our latest study, focusing on the hardest-hit north of the country, was published this morning 🧵

Heavy, deadly monsoon rainfall in Pakistan has become more intense with climate change - about 15%, but it could be as high as 40 - 80%: www.worldweatherattribution.org/climate-chan...

My book - ClimateINJustice is shortlisted for the @wainwrightprize.bsky.social ! Really happy about this, as it's not traditional conservation writing - but conserving & fighting for us humans & our rights wainwrightprize.com/shortlist-20...

New research from @wwattribution.bsky.social and ‪@fahadiii.bsky.social‬ shows that climate change made Pakistan’s deadly monsoon floods ~15% heavier. Flooding killed at least 300 people. Events like these underscore the danger of overshooting 1.5°C. www.worldweatherattribution.org/climate-chan...

Our first attribution study from WASITUS (yes we did torture that acronym) on the July heatwave in Ireland is out: www.rte.ie/brainstorm/2.... The project aims to provide operational attribution on future noteworthy events and when not required nationally row in + support @wwattribution.bsky.social

A short article on our 'mini-heatwave' study has been published by @rtebrainstorm.bsky.social. This is the first report by the new @wasitusie.bsky.social project with @peterthorne.bsky.social. Funded by EPA and in conjunction with Met Éireann and @wwattribution.bsky.social

Extreme rainfall hit Colombia and Venezuela in late June. One landslide near Medellín killed 27 people. Our latest study couldn’t determine how climate change influenced the downpours. Why? A scarcity of data and poor model performance. 🧵 📷: Alcaldía de Bello

What caused deadly landslides in Colombia? Finding out, should be easier. Tropical climates are complex, but if data are held by companies & organisations hiding them behind walls of bureaucracy it becomes impossible. @wwattribution.bsky.social study: www.worldweatherattribution.org/growing-expo...

#climatecrisis tripled death toll in Europe’s June heatwave, study finds - Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say theguardian.com/environment/...

About 1500 of the approx. 2300 people that will have lost their lives across 12 European cities last week would still live, if it wasn't for our burning of oil, coal and gas. If we care about the right to life, we need to stop burning fossil fuels. www.imperial.ac.uk/grantham/pub...

⚠️Climate change tripled death toll in 12 European cities during last week's heatwave rapid analysis by @imperialcollegeldn.bsky.social & @lshtm.bsky.social estimates. 🌡️ The study also found that climate change increased heatwave temperatures up to 4°C across the cities 🧵

Without our continued burning of fossil fuels, the current heat in London & most of the UK would not have been a heatwave: www.worldweatherattribution.org/climate-chan... Heatwaves are dangerous. Drink water, lots of it, stay cool, even if you feel invincible, you're probably not.

Heat kills. Our colleagues estimate nearly 600 people in England and Wales could die prematurely in the heatwave. We found that climate change made it 2-4°C hotter. The two real-time studies highlight that every fraction of a degree of warming will expose more people to potentially fatal heat.

The heat above 32°C in southeast England tomorrow will be 100 times more likely due to fossil fuel-driven warming 🌡️📈 Our super rapid study was published this morning. It is just the second time we’ve studied an event in real-time, using forecast data. It's been hot work. 🧵

🌡️ Saturday’s 32°C heat in SE England would’ve been a once in 2,500 year event without climate change. Now? 100x more likely Dr Ben Clarke & Dr @frediotto.bsky.social of @wwattribution.bsky.social, who led the research, are clear - this wouldn’t be a heatwave without human driven warming
