Story summary

Researchers at University of California, Berkeley show Earth's seasons are not synchronized, even in neighboring regions.
The study relies on 20 years of satellite data and shows Tucson and Phoenix in Arizona have different rainfall patterns.
Seasonal asynchrony can drive evolutionary divergence among species.
The study, published in Nature, urges climate models to account for local seasonal variations and predict impacts on biodiversity, agriculture, and human health.
