Researchers remove solar-powered sensors from a coast redwood at Northern California's Humboldt Redwoods State Park. Photo by Michael Nichols/National Geographic Stock. Photo is used to illustrate a story in the current Sierra Magazine about the research that shows the latest threats to the coast redwoods. For those that haven't been cut down, or aren't otherwise endangered by mismanagement etc., it's the effects of the Climate Crisis, such as the decrease in coastal fog which provides the redwoods with the moisture they need. The redwoods are of an ancient species that has survived changes for thousands of years, but it is the unprecedented speed of climate-related change that most threatens them now. And that's true of a lot of other lifeforms that aren't so immediately threatened by obvious and radical changes in habitat, like the polar bears or the plants and animals in areas of what looks like permanent drought.
