SNOWDEN: Yes, he's on his laptop. And we're looking at the man behind the device. And in his lap is a little boy, a toddler, who's just playing on the keyboard. And the father's smiling. And the little boy looks at the webcam. It's just a glimpse, but to me it seems as though he's looking at me. And it reminds me of my childhood, of learning about technology with my own father. And I realize this man has done nothing wrong. He's just trying to get a job. He's just trying to study. He's just trying to get through life like all of us are. And yet, he's caught up. His children are caught up. We are all caught up by a system that we were not allowed to know existed. We were not allowed to vote whether this was proper or improper, and courts were not allowed to assess - open courts, real courts - whether it was proper and constitutional. Where do we go from there?

The politics show it, growing only more jagged. It has been just three years now since the historic signing of the Paris climate accords, which formalized the two-degree goal, and here is what has happened in the meantime: Donald Trump was elected president of the United States, pledging to boost coal, kill wind power, and roll back environmental regulations so aggressively that the industry groups he was theoretically appealing to have objected; Jair Bolsonaro was elected president of Brazil, promising to deforest the Amazon at such a rate that scientists of his own country estimated the impact would be, over the course of a decade, equal to adding a second China and a second U.S. to the global carbon footprint, if only for a year; and Xi Jinping appointed himself president for life of China, a booming autocracy that has, just this year, proposed new coal plants to single-handedly push us past the Paris goals.
