There seems to be a passive alliance between Vladimir Putin and Donald Trump and that's unprecedented in its form and dangerous in its content, because Russia is our most dangerous geopolitical opponent because of the desires that they have in the Middle East and because of their desire to break up Europe. And in the United States, we spent a lot of blood and a lot of treasure trying to keep Europe intact and democratic, and trying to keep the Middle East from being only influenced by people who are massive fans of [Syrian President] Assad and massive fans of the Iranians.

We seem to forget that everything that is good for the environment is a job. Solar panels don't put themselves up. Wind turbines don't manufacture themselves. Houses don't retrofit themselves and put in their own new boilers and furnaces and better-fitting windows and doors. Advanced biofuel crops don't plant themselves. Community gardens don't tend themselves. Farmers' markets don't run themselves. Every single thing that is good for the environment is actually a job, a contract, or an entrepreneurial opportunity.

In the fourth quadrant (lower right), working-class people are motivated to take on green-collar jobs and start green businesses.

Distorting attacks when people already don't trust you is not smart.

Even if we can solve the carbon problem for coal, it is still a non-renewable resource. At some point, coal supplies will drop.

Trump is holding together the shakiest coalition that you could conceivably govern on. It is a conservative, populist alliance that agrees with itself on very little.

The question is: do we pay a little bit more now? Or do we pay a whole lot later? For the equivalent of a postage stamp a day for each American, we can put a price on carbon today that will send a signal to private capital to invest in the clean technologies of tomorrow. Taking a vast portfolio of new energy solutions to scale will ultimately drive down costs through competition.
