As long as we continue to burn fossil fuels, the science tells us that these events will grow worse.

The impact is a "textbook case of climate injustice."

90% of homes in some impacted areas are made of sun-dried earth - structures that simply cannot withstand rainfall of this intensity.

Vulnerable communities are paying the price for a crisis they didn't cause. (3/4)

The current weak La Niña phase naturally brings wetter conditions to the region, but it is now operating in a much warmer, moisture-rich world.

While still a rare 1-in-50 year event, climate change acted as a "force multiplier," turning a heavy rain event into a more deadly deluge. (2/4)

💡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...

The full study is now available here: www.worldweatherattribution.org/climate-chan... 6/6

Those with access to cooling relied heavily on solar - which met 60% of the peak demand during the heatwave - a major contrast from the fossil-fuel heavy responses to previous heatwaves. 5/6

That has a human cost: Melbourne’s airport saw temperatures top out at 44.4°C on Jan 9 and one hospital reported a 25% spike in emergency admissions. Heatwaves kill more Australians than all other natural hazards combined. 4/6

Yet the world continues to heat with 2.6°C of warming expected by the end of the century under current global policies. This would turn a once rare event into a normal part of the Australian summer. 3/6

Even with a weak La Niña - which typically brings cooler weather - fossil fuel emissions "far outweighed" natural cooling. This heatwave was 1.6°C hotter than it would have been in a world without human-caused warming. 2/6

🚨 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

Spain and Portugal wildfire weather made 40 times more likely by climate crisis, study finds Wildfires were 30% more intense than would have been expected without global heating, scientists say

🚨 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) 🌍🔥

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

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...

Climate Change Made Turkey, Greece Wildfires 10 Times More Likely Hot, dry and windy conditions in the eastern Mediterranean will happen more often in a warmer world.

🌡️ 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. 🔥

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.

🔥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 🧵

Climate Change Made Turkey, Greece Wildfires 10 Times More Likely Hot, dry and windy conditions in the eastern Mediterranean will happen more often in a warmer world.

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

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:

Imperial researchers take leading role in major IPCC climate report | Imperial News | Imperial College London Imperial has more authors contributing to a crucial report on climate change than any other organisation in the world.

🌍 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.

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".

YouTube video by Climate Analytics Flash floods kill more than 300 in Pakistan

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

Indigenous Sámi have herded reindeer for more than 1000 years. But now, hotter summers cause reindeer to overheat and seek relief in urban areas. Warmer winters mean more snow falls as rain and alternating freeze and thaw creates layers of ice that prevent reindeer from digging for food.
