I'm excited to join @climatecentral.org's Monthly Climate Brief on Thurs, Mar 19. We'll be talking about (surprise!) what is happening this spring and how you can get involved in tracking signs of the season. We'd love to have you join us! #phenology #statusofspring @usa-npn.bsky.social

Early signs of spring in WY - buds swelling on trees & shrubs. Lots of potential for subsequent freeze events there. www.newslj.com/local-trees-...
@usa-npn.bsky.social growing degree day anomaly map clearly shows how much warmer than normal it has been so far this year #phenology #statusofspring

When does spring start in 2026? As milder air sweeps across the UK it could start to feel positively spring-like in places. But when does spring officially begin?

A great reminder of the differences among astronomical, climatological, and phenological spring: www.bbc.com/weather/arti...

All that cold the L48 recently experienced really slowed down the onset of spring. But we are starting to see things pick back up, with extra-early activity in the TX panhandle and through parts of AZ, CA, and up the west coast

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...

Analysis | You’re not crazy. Spring is getting earlier. Find out how it’s changed in your town. Readers told us how spring has changed where they live. Look up your town to see when leaves are sprouting and how spring’s arrival time has changed.
