Health Insurers Fret About Climate Change

On ice-free summers, health insurance premiums, and ESG investing

Current conditions: Much of the U.S. will see calmer weather over the next few days • A tornado caused “biblical damage” in Cyprus • Mexico is experiencing its worst drought in 12 years.

THE TOP FIVE

1. Study: Polar bears head ashore for food as sea ice melts

A new study sheds light on how polar bears are changing their diets and behaviors in a warming world. Climate change is shrinking the sea ice on which the bears rely for hunting seals. As the ice melts, the bears are forced onto land, where they can either reduce their physical activity in order to save energy and calories, or forage for berries and small prey. The research, which involved strapping cameras to 20 bears in Canada’s Manitoba province, found that neither option is enough to prevent the animals from going hungry. All of them lost weight and two of them were on track to starve before the sea ice was expected to return. “Polar bears are not grizzly bears wearing white coats,” said Charles Robbins, director of the Washington State University Bear Center and co-author of the study in the journal Nature Communications. “They’re very, very different.” The study found some bears are spending more time in the water, which is “new and unexpected,” one polar bear expert told Vox. “These are possibly acts of desperation. Hungry and skinny bears take more risks than fat bears.”

2. Health insurers fret about climate change impact

Health insurance may be the next sector to hike premiums due to climate change, The Wall Street Journal reported. The rise in extreme weather events has already roiled the home insurance market, making it more expensive – or even impossible – for homeowners in some high-risk areas to take out a policy. Now health insurers are “building new models to reassess premiums, estimate risk, and meet incoming climate reporting standards,” the Journal said. Recent research has linked extreme heat and wildfire smoke to a variety of health problems including heart attacks and cancer, and insurers want to know what this all means for their bottom lines. But the Journal reports that for now, insurers aren’t worried about their profits, “because the groups most likely to be affected by climate change aren’t covered by insurance.”

3. Redfin adds air quality tracker to home listings

In a sign of the times, Redfin has become the first real estate brokerage to include air quality data alongside home listings. The feature allows house hunters to see the air quality in their prospective new neighborhoods, and tells them whether it is expected to get better or worse in years to come. One home listed in Washington, D.C., for example, came with this warning: “Over the next 30 years, this area will experience a 20.0% increase in the number of poor air quality days, i.e. where the Air Quality Index (AQI) exceeds 100.”

Redfin already lists other risk factors like flood, fire, heat, and wind. “Redfin wants to ensure that every single person searching for a home has the information they need to understand climate risks,” said Redfin Senior Vice President of Product and Design Ariel Dos Santos. The company also published data this week showing that more people are moving into than out of metro areas that have bad air quality, not necessarily because of health concerns, but because they’ve been priced out.

4. BlackRock’s ESG funds are ‘soaring’

BlackRock Inc., the world’s largest asset manager, has seen more cash flow into its ESG funds than out every quarter for the last two years, “a period that marks one of the toughest ever in the two-decade history of environmental, social and governance investing,” Bloomberg reported. Most people might associate ESG with renewables, but it also encompasses some of the biggest tech giants: BlackRock’s three top-performing ESG funds include Microsoft and Apple as their biggest holdings.

  • 5. UK Royal Navy reportedly considering climate change course for sailors

    The United Kingdom’s Royal Navy is considering making all its sailors take a course about climate change, The Telegraph reported, citing a leaked document. The course would focus specifically on how climate change threatens peace and defense efforts. The document also said rising sea levels could damage maritime infrastructure. Other initiatives under consideration include paying for sailors to study climate change, and inviting climate scientists to conduct research on Britain’s warships. One former head of the Royal Navy told the paper he supported the plans, but added: “Climate change is not more important than fighting the King’s enemies, so it has to be done with a balance.”

    Heatmap’s Annual Climate Insiders Survey Is Here

    Rob takes Jesse through our battery of questions.

    Every year, Heatmap asks dozens of climate scientists, officials, and business leaders the same set of questions. It’s an act of temperature-taking we call our Insiders Survey — and our 2026 edition is live now.

    In this week’s Shift Key episode, Rob puts Jesse through the survey wringer. What is the most exciting climate tech company? Are data centers slowing down decarbonization? And will a country attempt the global deployment of solar radiation management within the next decade? It’s a fun one! Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

    Climate Insiders Want to Stop Talking About ‘Climate Change’

    They still want to decarbonize, but they’re over the jargon.

    Where does the fight to decarbonize the global economy go from here? The past 12 months, after all, have been bleak. Donald Trump has pulled the United States out of the Paris Agreement (again) and is trying to leave a precursor United Nations climate treaty, as well. He ripped out half the Inflation Reduction Act, sidetracked the Environmental Protection Administration, and rechristened the Energy Department’s in-house bank in the name of “energy dominance.” Even nonpartisan weather research — like that conducted by the National Center for Atmospheric Research — is getting shut down by Trump’s ideologues. And in the days before we went to press, Trump invaded Venezuela with the explicit goal (he claims) of taking its oil.

    Abroad, the picture hardly seems rosier. China’s new climate pledge struck many observers as underwhelming. Mark Carney, who once led the effort to decarbonize global finance, won Canada’s premiership after promising to lift parts of that country’s carbon tax — then struck a “grand bargain” with fossiliferous Alberta. Even Europe seems to dither between its climate goals, its economic security, and the need for faster growth.

    Now would be a good time, we thought, for an industry-wide check-in. So we called up 55 of the most discerning and often disputatious voices in climate and clean energy — the scientists, researchers, innovators, and reformers who are already shaping our climate future. Some of them led the Biden administration’s climate policy from within the White House; others are harsh or heterodox critics of mainstream environmentalism. And a few more are on the front lines right now, tasked with responding to Trump’s policies from the halls of Congress — or the ivory minarets of academia.

    We asked them all the same questions, including: Which key decarbonization technology is not ready for primetime? Who in the Trump administration has been the worst for decarbonization? And how hot is the planet set to get in 2100, really? (Among other queries.) Their answers — as summarized and tabulated by my colleagues — are available in these pages.

    Will Data Centers Slow Decarbonization?

    Plus, which is the best hyperscaler on climate — and which is the worst?

    The biggest story in energy right now is data centers.

    After decades of slow load growth, forecasters are almost competing with each other to predict the most eye-popping figure for how much new electricity demand data centers will add to the grid. And with the existing electricity system with its backbone of natural gas, more data centers could mean higher emissions.
