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.

Microsoft Sustainability Chief Hounded by Protestors at Seattle Climate Week

Protestors interrupted one of the final sessions of PNW Climate Week — a conference that brings together climate leaders across Washington, Oregon, and British Columbia — objecting to Microsoft’s rising carbon emissions from data centers and partnerships with oil and gas companies. The company’s Chief Sustainability Officer Melanie Nakagawa was having a one on one conversation with GeekWire climate reporter Lisa Stiffler at Seattle’s City Hall when protestors carrying signs reading “Microsoft’s AI pollutes” and other slogans began shouting from the audience.

I was there, having just moderated the prior panel on how to finance Washington’s clean energy ambitions. Early on there were some rumblings in the crowd from up front. “Climate leaders don’t build gas pipelines in Moses Lake,” was the first objection I heard clearly. It came shortly after Nakagawa kicked off the conversation by highlighting Microsoft’s partnership with sustainable aviation fuel startup Twelve, which recently opened its first commercial-scale SAF plant in Moses Lake, Washington. The tech giant has supported the project through a strategic investment from its Climate Innovation Fund, as well as an offtake agreement for the fuel that will help offset its emissions from employee travel.

If you live anywhere near the Great Lakes or Mid-Atlantic (or certain parts of the Mountain West), odds are it’s smoky where you live. Wildfires raging in western Ontario are sending smoke cascading south and east across the U.S., prompting widespread air quality alerts affecting millions of Americans.

The good and — very bad — news is that we’ve been here before. Here’s a look back at some of Heatmap’s coverage from the summer of 2023, when smoke produced by forest fires in Quebec blanketed 128 million people in a murky haze and turned the New York City skyline an ominous shade of orange.

With higher temperatures come higher electricity bills. Whether through higher seasonal charges or greater usage, Americans across the country were paying more for electricity in June.

In Virginia, the epicenter of the data center boom, the typical household electricity bill was $192 in June, up from $172 in June of last year, according to the latest data from the Heatmap and MIT’s Electricity Price Hub. Rates, meanwhile, were about 18 cents per kilowatt-hour, compared to just over 15 cents in June of last year, a 12% hike. Rates were also up from the end of last year, when they were about 15.5 cents.
