Every Single Day of 2023 Was Extraordinarily Hot

Here are some more numbers from today’s big temperature announcement.

You have almost certainly heard already that 2023 was, officially, the hottest year on record. That announcement came this morning from Copernicus, the European Union’s Earth data service.

There was another figure in that announcement, however, that caught my eye: 2023 was also the first year in which every single day was at least 1 degree Celsius hotter than the pre-industrial average.

That is a marked contrast to 2022, our sixth hottest year on record, which had several days less than 1 degree above the pre-industrial average and a maximum temperature difference around half a degree lower than last year’s.

Just for kicks, I decided to make the same chart for 1940, the earliest year represented in this particular dataset. As you will perhaps notice, I had to adjust the scale to account for temperatures below the pre-industrial average.

The last time the global daily average temperature came in below the pre-industrial average, according to the Copernicus data, was October 8, 1992.

Trump’s Offshore Wind Ban Is Coming, Congressman Says

Though it might not be as comprehensive or as permanent as renewables advocates have feared, it’s also “just the beginning,” the congressman said.

President-elect Donald Trump’s team is drafting an executive order to “halt offshore wind turbine activities” along the East Coast, working with the office of Republican Rep. Jeff Van Drew of New Jersey, the congressman said in a press release from his office Monday afternoon.

“This executive order is just the beginning,” Van Drew said in a statement. “We will fight tooth and nail to prevent this offshore wind catastrophe from wreaking havoc on the hardworking people who call our coastal towns home.”

A top aide to incoming President Donald Trump is claiming the president-elect wants the U.S. to acquire Greenland to acquire more rare minerals.

“This is about critical minerals. This is about natural resources,” Trump’s soon-to-be national security advisor Michael Waltz told Fox News host Jesse Watters Thursday night, adding: “You can call it Monroe Doctrine 2.0, but it’s all part of the America First agenda.”

An Insurance Startup Faces a Major Test in Los Angeles

Kettle offers parametric insurance and says that it can cover just about any home — as long as the owner can afford the premium.

Los Angeles is on fire, and it’s possible that much of the city could burn to the ground. This would be a disaster for California’s already wobbly home insurance market and the residents who rely on it. Kettle Insurance, a fintech startup focused on wildfire insurance for Californians, thinks that it can offer a better solution.

The company, founded in 2020, has thousands of customers across California, and L.A. County is its largest market. These huge fires will, in some sense, “be a good test, not just for the industry, but for the Kettle model,” Brian Espie, the company’s chief underwriting officer, told me. What it’s offering is known as “parametric” insurance and reinsurance (essentially insurance for the insurers themselves.) While traditional insurance claims can take years to fully resolve — as some victims of the devastating 2018 Camp Fire know all too well — Kettle gives policyholders 60 days to submit a notice of loss, after which the company has 15 days to validate the claim and issue payment. There is no deductible.
