This year is the first time I've seen the trees on my street blooming in February. It isn't my imagination. Maps from the USGS-led USA National Phenology Network indicate where Mother Nature began thinking that spring arrived in February. The data, updated daily, comes from observations of budding trees, blooming flowers, and animal behavior. The map shown here is the Spring Leaf Index Anomaly for March first. The area in red indicates where the data shows spring arriving unusually early. -via Digg
