The United Nations released a major climate change report last week saying we have to cut emissions even more than we previously thought to avoid catastrophe from global warming. And we have to do it more quickly. Those who doubt that humans can cut emissions enough might point to solutions that lean toward engineering, instead; things like carbon capture to take carbon pollution out of the air and store it. But is new technology, on its own, a real fix? Scott Waldman reports on climate change for E&E News. He says it's important to remember tech got us here in the first place. The following is an edited transcript of Waldman's conversation with Marketplace's Jed Kim.
Scott Waldman: The two biggest sources of pollution in this country are power plants and vehicles. So we're looking at both of those, and we have technology to bring down the emissions for both of those. But there's still tremendous potential. We've also seen a tremendous increase in solar power, in people putting [solar] panels on their houses in the last decade. And there's far more potential there. But it's not going to happen without some sort of government subsidy, I think, to shift the marketplace even more strongly.
