Ed Whittingham calls himself "a climate citizen at large." He's also the host of the Energy vs Climate podcast, the former executive director of the Pembina Institute and the host of a new podcast called "Scrubbing the Sky."

He says we will have to do more than transition our energy systems to zero-carbon sources to combat climate change.

To stave off the worst impacts of climate change he says we will need to remove carbon from the atmosphere by scrubbing the sky.
