Current conditions: Debris left behind by Halley’s Comet is set to create a meteor shower across the sky tonight into tomorrow morning • Super Typhoon Champi is roaring just east of the Philippines’ most populous island, Luzon, with winds of up to 133 miles per hour • The heat wave roasting East Africa is driving temperatures in the Sudanese capital of Khartoum past 106 degrees Fahrenheit.


THE TOP FIVE

1. We’re already feeling 1.5 degrees Celsius. Now we’re locking it in.

El Niño is giving us a taste of what the warming we have locked in as a species will feel like. Just look at the extreme weather that raged this summer in the form of storms and heat waves as the cyclical weather pattern drove up temperature averages past 1.5 degrees Celsius above pre-industrial levels. That’s the maximum warming benchmark set in the 2015 Paris Agreement, later reinforced in a landmark 2018 United Nations report. Now the latest data from the UN Environment Programme shows that we’re well on our way to making this year’s El Niño the new norm. A report released Wednesday suggests the current trajectory of emissions means the “lowest possible” warming scenario would lead to global temperatures peaking at about 1.7 degrees to 1.8 degrees by midcentury before potentially returning to 1.5 degrees by 2100. To put the world on that pathway, global emissions would need to fall by 18% in the next three years relative to 2025 levels. Then 45% by 2035. Then another 69% by 2040.

The World’s First Subsea Geothermal Well Had 8.7 Seconds of Glory

Endurance Energy hoped its generator would run for a full year, but the team isn’t afraid of the “error” in “trial and error.”

About 300 miles off the Oregon coast, a mile beneath the ocean’s surface, a startup just drilled the world’s first subsea geothermal well. And for a grand total of exactly 8.7 seconds, its prototype power plant generated about 2 kilowatts of net power. It wasn’t quite the result the Seattle-based Endurance Energy was hoping for — the company’s goal was to run its 100-kilowatt generator for a full year. But it’s not nothing.

“We really proved with this mission that a geothermal well could be drilled and completed on the seafloor, and doing that within 21 months of the company existing I think is really a testament to our pace of progress,” Endurance CEO Andrew Redd told me.
