The National Phenology Network released a cool visualization tool this year that tracks when the first spring leaf showed up around the US. After a winter that felt freakishly mild, many places saw the earliest signs of spring on record, with Dallas 15 days earlier, Cincinnati 24 days earlier, and New York City 33 days earlier. However, on parts of the West Coast, spring arrived late in LA by 6 days and in Pelton, Arizona, by 30 days. This pattern aligns with how winter weather in the West was cooler and wetter than usual while the east was warmer than usual. This long-term trend is due to climate change and can have devastating impacts, such as disrupting animal and insect migration patterns and causing an earlier and longer allergy season.
