A Climate Database Melts Away

On the new stove efficiency rules, a Swiss glacier, and more

Current conditions:Light snow is still falling in parts of Massachusetts after a storm brought 8 inches of snow to parts of the state on Sunday and Monday. Residents in Queensland, Australia, are evacuating as thunderstorms inundate towns on the coast. California is still waiting for an atmospheric river to dump rain on the state, which should start tomorrow.


1. U.S. finalizes stove efficiency rules

Yesterday, the U.S. Department of Energy finalized energy efficiency rules for both gas and electric stoves that the agency says will save consumers around $1.6 billion in energy costs over 30 years, according to Bloomberg. The standards, which are scheduled to take effect in 2028, won’t ban gas stoves, but should reduce carbon dioxide emissions by an estimated 4 million metric tons over three decades.

2. A vast archive of climate data literally melts away

Glaciers are treasure troves of information for scientists studying climate change. Ice core analysis can often give researchers a detailed look at the composition of the atmosphere over time, which in turn tells us just how human-caused pollution affects the climate. The problem, of course, is that climate change also makes glaciers melt — and now one of them, the Corbassière glacier in Switzerland, has degraded so much that it’s no longer viable for research, its ice cores a muddled mess of meltwater.

“The climate archive is destroyed,” scientists at the Paul Scherrer Institute wrote in a statement. “It is as if someone had broken into a library and not only messed up all the shelves and books, but also stole a lot of books and mixed up the individual words in the remaining ones, making it impossible to reconstruct the original texts.”

3. Sustainable foods could have a $10 trillion upside

Global food systems are “destroying more value than they create” and in dire need of an overhaul, according to a new assessment from the Food System Economics Commission (FSEC). By rethinking the way we approach food, the authors say, we could create up to $10 trillion in health and economic benefits around the world.

As Justine Calma writes in The Verge, that would mean both a tweak to our diets — the report doesn’t call for a worldwide shift to vegetarianism, but does advocate for a reduction in meat consumption — and a proper accounting in food prices of all the costs of production that we currently sweep under the rug. That latter bit could be an especially tough pill to swallow, and the study authors caution there would have to be institutional support for lower-income sections of society for fear of protests like the petrol price protests that gripped France in 2018, or the farmer protests ongoing in Europe.

Still, the report states, the benefits would far outweigh the costs, with undernutrition potentially eradicated by 2050, 174 million premature deaths from diet-related chronic disease prevented, and the environmental impacts bringing countries closer to their Paris Agreement goals.

4. Avian flu comes for birds of all feathers

Avian flu is devastating California’s “egg basket,” sweeping through Sonoma and Merced counties a year after a similar outbreak in the Midwest caused egg prices around the country to soar, according to the Associated Press. Over the past two months, commercial farms have had to slaughter nearly a million birds to contain the outbreak. The loss of those birds caused a temporary spike in the price of eggs in the Bay Area before more were brought in from outside the region; it remains to be seen if this outbreak will become big enough to affect prices in other parts of the country as well.

Further afield, at least two penguins in the Antarctic have died from bird flu, writes Phoebe Weston in The Guardian. One gentoo penguin is confirmed to have died from the virus, and scientists suspect it also took out one king penguin — if confirmed, that would be the first of its species to be killed by the deadly H5N1 variant. Last year, scientists warned about “one of the largest ecological disasters of modern times” if the virus reached Antarctic penguin populations; the birds are currently clustered for breeding season, which means it could soon turn into a superspreader event.

5. GoFundMe for climate disasters is helping the wealthy most

A new report analyzing post-disaster crowdfunding campaigns has found that cash raised through sites like GoFundMe disproportionately benefits the wealthy. The main reason, Christopher Flavelle writes in The New York Times, appears to be social networks: Wealthy people are more well-connected, particularly to other wealthy people, and so inevitably get more money. It’s a showcase of why we need to prioritize governmental support for disaster victims; as one of the study authors told Flavelle, “we cannot count on this form of private charity to fill funding gaps.”


Scientists have, for the first time ever, captured footage of a newborn Great White Shark. The finding means researchers could, finally, figure out where the sharks birth their young — and in turn lead to greater environmental protections in previously unprotected patches of ocean.

The Electrolyzer Tech Business Is Booming

While the latest hydrogen hype cycle may be waning, investment in the fundamental technologies needed to power the green hydrogen economy is holding strong. This past week, two major players in the space secured significant funding: $100 million in credit financing for Massachusetts-based Electric Hydrogen and $111 million for the Australian startup Hysata’s Series B round. Both companies manufacture electrolyzers, the clean energy-powered devices that produce green hydrogen by splitting water molecules apart.

“There is greater clarity in the marketplace now generally about what's required, what it takes to build projects, what it takes to actually get product out there,” Patrick Molloy, a principal at the energy think tank RMI, told me. These investments show that the hydrogen industry is moving beyond the hubris and getting practical about scaling up, he said. “It bodes well for projects coming through the pipeline. It bodes well for the role and the value of this technology stream as we move towards deployment.”

It was my first truck-powered cocktail party.

General Motors had gathered journalists at a Beverly Hills mansion last week for a vehicle-to-home show and tell. GM’s engineers outfitted the garage with all the components needed for an electric vehicle’s battery to back up the house’s power supply. Then they tripped the circuit breaker to cut off the home from grid power and let the plugged-in Chevy Silverado electric pickup run the home’s lights and other electrical systems for the remainder of the gathering.

1. Severe storms in Houston kill 4

At least four people were killed in Houston last night when severe storms tore through Texas. Wind speeds reached 100 mph, shattering skyscraper windows, destroying trees, and littering downtown Houston with debris. “Downtown is a mess. It’s dangerous,” said Houston Mayor John Whitmire. Outside Houston, winds toppled powerline towers. At one point 1 million customers were without power across the state, and many schools are closed today. The storm front moved into Louisiana this morning, prompting flash flood warnings in New Orleans.
