New York City and Brooklyn: noticed the trees budding and starting to put forth leaves and flower buds. There was a nice rain last night, and it's been warm for a week or two in a row. I assume that is what did it.
Just keeping track of this for my own interest, getting a feel for when things begin to grow again after winter.
Also it's beautiful and makes me happy to look at. Spring. Real spring. Hopefully we don't get any frosts like has been happening in Iowa, where it's warm for a few weeks, the trees start to bud and bloom, and then we get a frost that kills everything. I'm pretty sure that's a new development due to climate change.
