Urban Heat Island Mapping Campaign seeks Twin Cities volunteers

MINNEAPOLIS — Extreme heat isn't just dangerous — it can be deadly. That's why scientists need your help this summer.

Hennepin and Ramsey counties are participating in the Urban Heat Island Mapping Campaign.

Volunteers will mount heat sensors on their cars, then they'll drive planned routes to collect temperature and humidity data.

The mapping project is planned for the last Saturday in July. Volunteers get a $25 debit card for helping.

WCCO examined urban heat islands last year in an edition of Good Question.
