The New England Aquarium took on vehicles and climate change during a Tuesday panel called “Roadside Assistance: Driving Change on Our Streets and in the Oceans.” The event featured insight from auto experts such as Consumer Reports auto editor Eric Evarts; Zipcar CEO Scott Griffith; car magnate Herb Chambers; and Ray Magliozzi of “Car Talk,” who told people to stop letting their cars idle. WBZ’s Lisa Hughes moderated the discussion.
