🌱 You’re not crazy. In much of the U.S., spring really is getting earlier.

For my Climate Lab column, I built a tool that lets you look up how the timing of spring leaves has shifted where you live since 1981.

It feels nice but we are doomed. Just imagine your child growing 5 Inch during the night. That is the kind of change we are experiencing.This is NOT GOOD.

thank you for this! I grew up knowing several periods every spring of cold snaps that fell about the time certain plants bloomed, and about when those were. ie, 'redbud winter', 'dogwood winter' etc. Now they're coming earlier and earlier. :(

I know your intentions are good, but by failing to distinguish between native plants, which are adapted to local climate, from nonnative plants, which are not, you reduce the credibility of the analysis. I don’t give a crap when ornamental magnolias flower.

I live in Saint Paul, MN and confidently planted a bunch of seeds yesterday. Which is weird. We should be staring down our springtime "just kidding, here is a blizzard" weather.

Have you considered doing one of these for the fall arrival of colors? I know that's more complicated, with variables including rainfall and sugar content in the leaves, but it'd be interesting to see. Robert Bardon at NC State has done a lot of work on this, at least for North Carolina.

I'm a Washington purple, and it sucks. Though our summers seem to be coming sooner and are so much hotter. We seem to just be getting less temperate overall.

Holland, Michigan has had a Tulip Time festival every spring for nearly a century. They had to reschedule it already back in the 1990s because the tulips were so often blooming and withering before the festival started.

Seattle had a local saying about the annual week of summer. It didn't even happen every year. So nothing built here prior to 15 years ago has AC. When I first moved here in 89 the local Ford dealer said they didn't have any cars with AC. Now we get hot and sunny every summer.

I've lived in my current home (western KY) for 11 years, longest I've lived in one house since High School, and in that time, each winter has been milder and each spring sooner. We have some severe cold days due to polar vortexes, but much less snow and outside of those plunges, winters are mild.

Can you explain that spot in North Dakota, and parts of Minnesota where the leaves are coming in much later than expected now? Like what effects are driving that?

🪴 Is global warming involved?

It's still impossible to forecast when leaves will arrive in any given year. But the long term trend shows that leaves’ average arrival date roughly matches the average temperature at the start of each year.

Yup, about 2 weeks earlier than it used to be. The turkey buzzard migration has also shifted earlier.

Thinking about the vast botanical richness of the Great Smokies, esp the spring ephemeral flowers. They're blooming far too early for their insect dependents, aren't they? (Cherokee NC: leaf-out is 16 days earlier)
