At https://www.sciencedaily.com/releases/2023/11/231101180644.htm … evaporation takes place all the time but scientists have been experimenting and they noticed something unusual about the rates water evaporates. They have found that light can cuse water to evaporate. The same story popped up at https://wattsupwiththat.com/2023/11/04/light-shaking-water/ … by a guest blogger. He said he had always thought they had already figured this out – but apparently not. Light strikes a water molecule and has enough energy to knick it loose from the liquid surface. He goes into say there are implications if the experiments are verified. It will make solar desalination projects cheaper but it will also mess up climate science. Water droplets at the top of clouds, for example. However, Anthony posted on the same subject a day later -see https://wattsupwiththat.com/2023/11/05/in-a-surprising-finding-light-can-make-water-evaporate-without-heat/

At https://www.livescience.com/planet-earth/flooding/rare-lake-forms-in-death-valley/ … an oasis teeming with ponds and wild flowers has formed at Death Valley National Park. One of the hottest and driest places in the world. It seems in the wake of Hurricane Hilary that a lot of water was dumped on the desert. The  new environment did not last long, though. A month later park officials were using a boat on the temporary lake but now there is little more than an inch or so of water left.
