The last time Cicadas appeared in NYC, the Brian Lehrer Show was called "On the Line," there was no such thing as an "embedabble map," and WNYC's Data News team didn't exist. Luckily that's all changed. John Keefe of WNYC Data News discusses their latest project: Cicada Tracker. WNYC is asking citizen scientists around the region to build a detector that reports back soil temperatures. When we begin to see consistent readings of 64° we'll know the cicadas or on their way!
