The will to act is a renewable resource.

I think it's harder for people than it should be. But as more and more of us become carbon neutral and change the patterns in our lives to be part of the solution instead of part of the problem, we are now beginning to see the changes in policy that are needed.

There are skeptics who do not come to their view because they have a source of income from carbon polluters. I don't mean to imply that they're all in that category at all. There are also those who are also not motivated by ideological resistance for any role of government. But I don't know of any arguments or any presenters of arguments that overturn the consensus that I think have gained any legitimacy.

Unless we act boldly and quickly to deal with the underlying causes of global warming, our world will undergo a string of terrible catastrophes.

Traditionally the United States has been the natural leader of the world. That's not just pride as an American speaking; it's just the reality. Without the U.S. being involved in Paris Climate Agreement, it's hard for the world community to move forward as effectively.

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.
