The 2024 #BulletinAMS State of the Climate Assessment is out today. @usa-npn.bsky.social contributed data & info about how #phenology is changing in the U.S. The timing of plant and animal activity such as leaf-out is a strong indicator of species and ecosystem response to changing conditions.

Spring didn't really start out very interesting (arriving later than average in much of the south & west), but is showing up early in the middle of the country and creeping into the NE early now! #phenology #statusofspring @usa-npn.bsky.social www.usanpn.org/data/maps/sp...

We are seeing a real herky-jerky start to spring this year! Things might finally start picking up in the middle of the country after a long, cold spell... but the start to the season definitely is not notably early #phenology
