The day I made that statement, about the inventing the internet, I was tired because I'd been up all night inventing the Camcorder.

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.

Some of the most intriguing new research is in the area of extreme weather events and rainfall. A recent study by German scientists published in Climatic Change projects that extreme precipitation will increase significantly in regions that are already experiencing extreme rainfall. Man-made global warming has already increased the moisture content of the air worldwide, causing bigger downpours. Each additional degree of temperature increase causes another seven percent increase in moisture in the air, and even larger downpours when storm conditions trigger heavy rains and snows.

All I'm doing, all I have done for 40 years, is spend time with the best scientific experts, gain their confidence, and take advantage of their patience in explaining things to me over and over again in progressively simpler language that I can understand, so that I can read it back to them and get their sign off, where they say, "Yep, that's it, Al. You've got it." When I understand it, I know I can explain it to other people. When the scientists' predictions end up being true, I see that as an opportunity to say to people, "Listen carefully to what they're saying now."

We need to remake the Democratic party. We need to remake America.

The scientists are virtually screaming from the rooftops now. The debate is over! There's no longer any debate in the scientific community about this. But the political systems around the world have held this at arm's length because it's an inconvenient truth, because they don't want to accept that it's a moral imperative.

We have arrived at a moment of decision. Our home - Earth - is in grave danger. What is at risk of being destroyed is not the planet itself, of course, but the conditions that have made it hospitable for human beings.
