It’s starting to feel like spring outside around the Valley, but if it seems like it was a little cooler and wetter than normal for longer than normal, you’re not wrong.
In fact, according to the National Phenology Network, in parts of Arizona, spring only happens this late every 40 years.
Phenology, by the way, is the study of the relationship between climate and seasonal natural phenomena — mainly in plants and animals — the information is coming from volunteers across the country tracking when seasonal events occur in those plants and animals.
Theresa Crimmins is director of the USA National Phenology Network and a research professor in the School of Natural Resources and Environment at the University of Arizona. She joins The Show to about when spring is springing across the country.
