Spring just keeps getting earlier. Guess what’s behind it? 

In some parts of the country, the season just breezed in three weeks ahead of schedule. Balmy weather may seem like more good news after an already unseasonably warm winter, but pause a beat before you reach for your flip-flops.

According to the “spring index,” a long-term data set which tracks the start of the season from year-to-year, spring is showing up earlier and earlier across the United States.

The culprit behind the trend? Climate change. And it’s bringing a batch of nasty consequences. Early warmth means early pests, like ticks and mosquitoes, and a longer, rougher allergy season. Agriculture and tourism can be thrown off, too. Washington D.C.’s cherry blossomsusually draw crowds in April, for instance, but they’re projected to peak three weeks early this year.
