"Pricing El Niño is not the same as preventing its loss of life. Yet, many of those acting on its forecasts are using them to move money, not people, out of harm’s way," writes Justin S. Mankin in a new #ScienceEditorial. https://scim.ag/4huP0HI

"Pricing El Niño is not the same as preventing its loss of life. Yet, many of those acting on its forecasts are using them to move money, not people, out of harm’s way." My editorial for Science on why hedging El Niño is not the same as adapting to it: www.science.org/eprint/DU6FR...

"The amendment misconstrues the design and purpose of emissions scenarios; imposes an ad hoc evaluation standard that no emissions scenario ... can meet; [and] it would create confusion and errors into an assessment that already effectively and accurately communicates scenario dependence."

Rainfall intensity matters as much as how much rain falls. New in Nature: Corey Lesk and I show that daily-scale concentration of precipitation dries the land over the long-run, an effect as strong as total precipitation is climatological wetting. Paper here: www.nature.com/articles/s41...

nature.comMore concentrated precipitation decreases terrestrial water storage - NatureConcentration of precipitation in large events decreases land water availability, and this effect will further increase with a future warming climate.

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.

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. See here: zenodo.org/records/1687...

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." 🧪🔌💡

newscientist.comCan 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

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.

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. This 2021 op-ed feels relevant as we approach the 2025 dry season with low snowpack and reservoirs: shorturl.at/Uvsyv

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

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?

Human-caused increases in extreme heat caused ~$30T in losses over 1992-2013, mostly in the low-income world least culpable for warming. $300B/yr in climate financing is 17 times less than the costs of but one climate hazard, estimated with data a decade cooler. Paper here: tinyurl.com/3psfnt4p

As the governments of the world commit humanity to sailing by 1.5°C, a friendly reminder that our level of societal risk aversion—not science—remains the major uncertainty in setting the carbon budget. From Mathez & Smerdon, 2018, itself adapted from Meinshausen et al., 2009.
