Why would we build as unequal a renewable energy sector as we have built a fossil fuel sector? The nice thing about renewables is they're everywhere, so you don't have to have monopoly control in the same way.

In a world where profit is consistently put before both people and the planet, climate economics has everything to do with ethics and morality.

It is our great collective misfortune that the scientific community made its decisive diagnosis of the climate threat at the precise moment when an elite minority was enjoying more unfettered political, cultural, and intellectual power than at any point since the 1920s.

But we need to be very clear: because of our decades of collective denial, no gradual, incremental options are now available to us.

I see The Gap ads as being a great example of how branding has changed. Those Gap campaigns are pop culture. They've been incredibly powerful. They have had the kind of effect on culture that a hit band has. Just look at The Gap's Khaki swing ads, which were music videos. They had this tremendous impact on the industry - suddenly everything started looking like Gap ads and it became difficult to know who was co-opting whom and who was creating culture.

That's what's happening now. The world is being held up a mirror: "All roads lead here. Do you like it?" A lot of people don't like it. A lot of people are saying, "Wait a minute, if our system can produce that, there's something wrong with this system." That opening is ours to seize. It matters how we name it: It's not called Donald Trump. It's called capitalism.

A term like capitalism is incredibly slippery, because there's such a range of different kinds of market economies.
