I would distinguish between Donald Trump and the United States of America. Although he is president, he does not speak for the country on the climate change, and that was vividly illustrated in the aftermath of his speech pulling the US out of the Paris Agreement. Almost immediately, not only did the rest of the world double down on its commitments, but also here in this country, governors, mayors, business leaders, they said, we're still in the Paris Agreement, and they're doubling down. A lot of cities have now made a decision to go 100% renewable energy.

For a free country to continue thriving, there have to be regular reforms, because any society, any economy that stays in place, you're going to see repeated attempts to exploit the openings for twisting policy to the advantage of those who already have wealth and power.

From wherever the emissions come, they have the same effect: They trap much more heat from the sun, melt the ice, raise the sea level, cause stronger storms, floods, drought, bigger fires, generate millions of climate refugees, destabilize political systems, threaten the growing of food crops and cause a number of other catastrophic consequences which, taken together, threaten the basis for the future of human civilization on the Earth.

We have a planetary emergency. We have to find a way to create, in the generation of those alive today, a sense of generational mission.

A leapord never changes his stripes.

When fear displaces reason, the result is often irrational hatred and division.

George Orwell once wrote that a false belief sooner or later collides with physical reality, usually on a battlefield.
