This is by far the most serious crisis civilisation has ever faced.

Global warming is real and human activity is the main cause. The consequences are mainly negative and headed toward catastrophic, unless we act. However, the good news is that we can meet this challenge. It is not too late, and we have everything we need to get started.

I have always been fascinated with those who try to look over the horizon and see things that are coming at us.

You need to really scrub your investment portfolios, because I guarantee you, many of you are going to find them chock-full of subprime carbon assets.

Even if we give first priority to the destruction of terrorist networks, and even if we succeed, there are still governments that could bring us great harm. And there is a clear case that one of these governments in particular represents a virulent threat in a class by itself: Iraq. As far as I am concerned, a final reckoning with that government should be on the table.

There are many who still do not believe that global warming is a problem at all. And it's no wonder: because they are the targets of a massive and well-organized campaign of disinformation lavishly funded by polluters who are determined to prevent any action to reduce the greenhouse gas emissions that cause global warming out of a fear that their profits might be affected if they had to stop dumping so much pollution into the atmosphere.

The climate crisis requires a bottom-up, grassroots demand for solutions because the elites in many parts of the world are under the influence of old industry.
