Most frightening and/or depressing story: An economic model that underlies a lot of climate policy may be too conservative. I don’t think this matters much because the world is doing too little, too late even according to the conservative model. Meanwhile, the ice shelves holding back Greenland are in worse shape than previously thought.
Most hopeful story: Small modular nuclear reactors have been permitted for the first time in the United States, although it looks like the specific project that was permitted will not go through. Meanwhile construction of new nuclear weapons is accelerating (sorry, not hopeful, but I couldn’t help pointing out the contrast…)
Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: India somehow manages to maintain diplomatic relations with Palestine (which they recognize as a state along with 138 other UN members), Israel, and Iran at the same time.
