If I am brutally honest, there is only one motto I would give to the movement to stem climate change after the Glasgow summit: “Everyone wants to go to heaven but nobody wants to die.”

On the one hand, liberal greens will tell you that the world is ending — but that we must not use nuclear power, an abundant source of clean energy, to stave it off. On the other hand, conservative greens will tell you that the world is ending, but that we can’t burden people with a carbon tax or a gasoline tax to slow global warming.

On a third hand, suburban greens will tell you that the world is ending, but that they don’t want any windmills, solar farms or high-speed rail lines in their backyards.

On a fourth hand, most of today’s leaders will tell you that the world is ending, so at Glasgow they’ve all decided to go out on a limb and commit their successors’ successor to deliver emissions-free electricity by 2030, 2040 or 2050 — any date that doesn’t require them to ask their citizens to do anything painful today.

This is not serious — not when you’re talking about reversing all the ways that we have destabilized Earth’s systems, from ice caps and ocean currents to coral reefs and tropical forests to the density of carbon dioxide in the atmosphere. This is pretend.

I have nothing against Glasgow. I admire those leaders who are trying to inspire the world to cut CO2 emissions, preserve biodiversity and hold each other to account. But we will not decarbonize the global economy with a lowest-common-denominator action plan of 195 countries. Not possible.

We will get there only when Father Profit and risk-taking entrepreneurs produce transformative technologies that enable ordinary people to have extraordinary impacts on our climate without sacrificing much — by just being good consumers of these new technologies.

In short: we need a few more Greta Thunbergs and a lot more Elon Musks. That is, more risk-taking innovators converting basic science into tools yet to be imagined to protect the planet for a generation yet to be born.
