The global warming deniers persist in this air of unreality. After all, the entire north polar icecap, which has been there for most of the last 3 million years, is disappearing before our eyes. Forty percent is already gone. The rest is expected to go completely within the next decade. What do they think is causing this?

We the human species, are confronting a planetary emergency-a threat to the survival of our civilization that is gathering ominous and destructive potential...the earth has a fever. And the fever is rising...Indeed, without realizing it, we have begun to wage war on earth itself.

There are some bright spots, to be sure, but the internet is still in a Wild West phase, as was the case during the early age of the printing press as well.

Junkies find veins in their toes when the veins in their arms collapse. Developing tars sands is the equivalent.

Here`s my point. I don`t want you to be in a position years from now where you welcome Hillary Clinton and say actually you did win. It just wasn`t close enough to make sure that all the votes were counted or whatever. Elections have consequences. Your vote counts. Your vote has consequences.

There's a law of physics: For every action there's an equal and opposite reaction. And sometimes that shows up in politics and society. And I think that the reaction to President Trump's decision on the Paris Agreement has been much stronger than I had even hoped for. And the determination being expressed by so many people in state governments, city governments, in the business community, the investor community, is really heartening to me.

The constant drive for campaign dollars has distorted decision-making in Washington, DC, to the point where our systems can no longer effectively address complex, long-term problems like the climate crisis. Which brings me to my other major concern - the short-term focus of capitalism. It distorts the allocation of resources and the decision-making processes of companies.
