Subsidizing green tech now & putting a price on CO2 emissions in 2035 could get the US most of the way to net zero by 2050—& cost far less than delaying.

The Arctic is going to suffer 1.5C of “irreversible” warming even if we reduce global temperatures to preindustrial.
Meaning continued melt of sea ice & the Greenland ice sheet, in the best case.
This is one of several Arctic stories in my latest newsletter: icemushroom.substack.com/p/december-i...

One of the 1st sediment cores from Greenland shows a 500m thick ice dome melted entirely at warming similar to what we'll likely see by 2100.
"This is very direct evidence that the ice sheet is as sensitive as we feared to even a relatively small amount of warming." newscientist.com/article/2510...

Northern Greenland ice dome melted before and could melt again
Prudhoe Ice Dome disappeared during a warm period 7000 years ago. Global warming could cause similar temperatures by 2100, showing the ice sheet’s vulnerability

Happy 2026! To start the year, here's a tree ring chiton, a 5cm ocean mollusk that sticks to rocks. Instead of having obvious eyes on a head, it's got 100s of tiny eyes embedded in the hard plates on its back, each with a rock crystal to focus light. Its top is one big eye spying on the world above
