Can Los Angeles lower its own temperature by 3 degrees?

Don't let this rainy winter fool you.

Los Angeles is still in the midst of a drought and this summer will likely be another scorcher. L.A. Mayor Eric Garcetti says he wants to change that. Last week, he announced plans to decrease the city's temperature by 3 degrees over the next twenty years. One of the ways researchers are testing lower the heat is by replacing the city’s asphalt with high-tech material that’s more reflective.

But how feasible is that? And who will foot the bill?
