Yann Quilcalle, ETH Zurich – How Fossil Fuel Companies Have Contributed to Heatwaves

Curious about source attribution, but only 3 minutes, article or podcast? Here is a summary on how fossil fuels companies have contributed to heatwaves.

3. The third wave was researchers, thinking of applying this framework to other aspects. Some were already aligning with my ideas, but others were opening my eyes on others. I sincerely enjoy these moments, although I cannot advance on all fronts simultaneously.

Looking forward to the next steps!

2. The second wave was practitioners, interested in its application. A lot of potential, but communicating its interpretability isnt always easy... yet it works and it is worth it!

Since the publication in September, I have been surprised by the interest. I knew that it would draw some attention, but I did not imagine that much.
1. The first wave was the media, to cover the study. Altmetric sometimes misses info, Nature mentioned 958 news stories early January...

Last week, @carbonbrief.org listed the top climate papers that were the most featured in the media. Proud to have our paper in #8!
The paper here: www.nature.com/articles/s41...

In this 2021 CBC interview, I described climate denial as what was once "a local cancer that ultimately metastasized to infect our entire body politic"

Just before new year, @natureportfolio.nature.com reminded about our publication of September. Conducting this work was exhilarating, and it has been quite intense since the publication. Many have reached out with many diverse interests. 2025 was a turning point for progresses in source attribution!

Swiss court admits Indonesia islanders climate case against Holcim A court in Switzerland has decided to admit a legal complaint linked to global warming against Swiss cement maker Holcim which alleges the company is doing too little to cut carbon emissions, parties to the case said on Monday.

What do you mean by concentration here? If atmospheric concentration, there is already this paper (link.springer.com/article/10.1...) for the contribution of the carbon majors to the atmospheric concentration with a former version of the database.
Or that is a different type of concentration?

But I also want to thank deeply many others, coauthors, colleagues, throughout these past years (sorry for not listing all of you!)

Being part of the 2025 #TIME100Climate means of course a lot to me, but it recognizes as well the work of countless others that build a more sustainable future.

Thus I want to thank deeply my coauthors: @lukasgudmundsson.bsky.social, Dominik Schumacher, Thomas Gasser, Rick Heede, @cohelongo.bsky.social, @qlejeune.bsky.social, @shrutinath97.bsky.social, Philippe Naveau, @wimthiery.bsky.social, @carlschleussner.bsky.social, @soniaseneviratne.bsky.social

While the objectives were to fill in scientific gaps, we were aware of the implications, especially to inform about corporate responsibilities in the climate crisis.

Being listed acknowledges the importance of my work. Most of my efforts went into technical developments to bridge the gap between the Earth system and the human systems. Lately, i have also linked the emissions of 180 fossil fuel and cement producers to 213 heatwaves (bsky.app/profile/did:...)

Across institutions, countries and fields, we have brilliant people tackling interlinked questions: climate change, sustainability, inequalities, justice, and more. All these issues are crucial to build a better world, where all of us can progress together.

I'm also surprised, because I am just a postdoctoral researcher, and TIME lists here influential leaders. I know many researchers that I personally consider more influential than me. Having spent now a decade in climate sciences, at the interface with economics, I also know how rich our network is.

Dozens of heatwaves linked to carbon emissions from specific companies Nature - Nearly one-quarter of heatwaves would have been ‘virtually impossible’ without global warming — and can be attributed to the emissions of individual energy producers.

Systematic attribution of heatwaves to the emissions of carbon majors - Nature Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

A paper in Nature suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪

Scientists link hundreds of severe heat waves to fossil fuel producers' pollution A new study finds dozens of heat waves would be "virtually impossible" without the activity of major fossil fuel producers, including oil companies.

Spoke to @yannquilcaille.bsky.social and @soniaseneviratne.bsky.social about their new study in Nature.

They finds dozens of heat waves would be "virtually impossible" without the activity of major fossil fuel producers.

Thanks Naomi!
