Noteworthy that this type of analysis would not be much harder without an emissions reporting mandate.

EPA plans to roll back GHG reporting—just as we learn US transport emissions have cost the US economy $68B: zenodo.org/records/1708...

The proposal isn't deregulation, it’s a tax on Americans through unchecked pollution.

This important work is very consilient with our attribution of extreme heat to carbon majors in @nature.com earlier this year: tinyurl.com/nhffeezv

It is a great thing for science when independent groups with independent methods come to the same conclusions.

Left: Annual-scale direct economic damages to the U.S. economy from the U.S. electric power sector emissions over the 1973-2023 period in billions of U.S. dollars benchmarked to the 2015 dollar value ($US2015). Right: Cumulative direct economic damages from U.S. power sector emissions, equivalent to the integral under the curve at the left.

With the EPA targeting the Endangerment Finding, @ccallahan45.bsky.social, Alex Gottlieb, & I conducted an end-to-end attribution of climate damages from U.S. power sector emissions.

The result: $78 billion in climate losses to the U.S. economy over 1973–2023.

Evidence of human influence on Northern Hemisphere snow loss - Nature Snowpack reconstructions for major river basins in the Northern Hemisphere reveal that the snowpack has declined in almost half of the basins, with roughly one-third of the declines attributable to hu...

Last year, Alex Gottlieb and I showed the concerning nonlinear snow loss with warming that occurs around -8°C (www.nature.com/articles/s41...).

This year, we show why: it is a simple counting exercise of days above freezing. Our latest in @agu.org Water Resources Research: doi.org/10.1029/2024...

Promotional graphic for the AGU25 conference session titled "B008 - Advances in Understanding Water-Energy-Carbon Interactions." It announces a call for abstracts due July 30, 2025, at 23:59 EDT. The central question posed is: "How do water-energy-carbon interactions shape terrestrial biosphere responses to global change?" Key topics include coupling of water-energy-carbon cycles, bridging scales and processes, climate change sensitivities and impacts, and applications for climate resilience. The image features headshots and affiliations of invited speakers Julia Green (University of Arizona) and Gabe Kooperman (University of Georgia), and conveners YanLan Liu (Ohio State), Justin Mankin (Dartmouth), Dan Gianotti (MIT), Flavio Lehner (Cornell), and Xiangtao Xu (Cornell). The background shows a scenic natural landscape with trees.

Please consider joining our #AGU session on beautifully complex Water-Energy-Carbon interactions with a broad scope from theory to applied science.

Invited talks by Julia Green @juliakgreen.bsky.social and Gabe Kooperman.

Scientists Tally Oil Majors’ Climate Damage With Eye to Legal Liability New research breaks down economic losses from global warming and attributes them to individual companies. It could bolster lawsuits against big emitters.

See below, from the article itself (rather than AI) — you should read it!

I would gently offer that creating human benefit does not absolve you of the harms you also create. One can see that, in say, the pharmaceutical industry being held to account for the opioid crisis.

We are—as a nation—intentionally blinding ourselves at the precise moment we need to see our planetary insult most clearly.

As a former GISS postdoc, this is such a bummer, not least of which because the disruption and ambiguity can easily become a pretense for laying off many more highly trained and talented scientists dedicated to the public good.

Great point—please see here: rdcu.be/ei0T5

Can climate science attribute economic damage to major polluters? Climate researchers argue their science has advanced enough to directly link emissions from particular companies to damages from specific extreme weather events

This could be a big deal for the hundreds of climate lawsuits underway around the world. @jsmankin.bsky.social and @ccallahan45.bsky.social link emissions from specific fossil fuel companies to trillions of dollars in damages.

“I think this is going to be the future of climate litigation." 🧪🔌💡

What would be strange? The counterfactual is simply a world where one emitter forgoes their emissions.

apnews.com/article/clim... world's biggest companies have caused $28 trillion in climate damage, a new study estimates

In it we show the trillions of dollars of economic losses from extreme heat caused by the emissions of individual carbon majors.

That’s from just one hazard. The scope of loss, while massive, is just the tip of the iceberg.

We are systematically underestimating the costs of climate change.

Can scientists trace climate losses back to the emissions from individual fossil fuel companies?

Yes, we can.

The inimitable @ccallahan45.bsky.social and I provide an 'end-to-end' attribution framework that can be applied in many climate accountability contexts:

"What's that? The 10% that accounts for 60% of the country's wealth accounts for 50% of spending?"

This headline is an astounding (and gross) editorial sleight of hand.

Water memories are short in the American West. Just two years after the 2020–23 drought, the Southwest drifts back to its climatically preferred state: drought.

Projected runoff declines from plant physiological effects on precipitation - Nature Water This study shows that Earth system models disagree on the spatial distribution of plant-induced precipitation changes but indicate that plant responses are as likely to decrease runoff as they are to ...

High CO2 is expected to boost runoff via plant responses, but our results challenge this. Conditioning plant-driven runoff changes on plant-forced precipitation changes, we find runoff declines are as common as increases, with CO2-driven runoff boosts over just 5% of land: shorturl.at/4zM7N

It’s not an assumption. There has been an attribution of how WUS drought severity has been increased because of warming from people’s GHG emissions. Perhaps you should read this: www.science.org/doi/10.1126/...

It's great that these researchers recovered the same effect we identified using independent data.

Identifying climate impacts requires data. And data is reflective of the power, values, and priorities of the data collector.

MLB has high-speed cameras to isolate warming's influence on a batted ball, but no data on heat stress of ballpark staff & patrons.

What of the impacts we cannot track?

‘Mostly’ should read ‘disproportionately.’ But we need to run the numbers to see how the percent of total losses vary in income decile.

17 times less by 2030.
