I played a bit of a role as a journalist in waking people up to the idea that this era called the Holocene, the last 11,000 years, since the last ice age, had ended.

I wrote my 1992 book on global warming,

thinking about all that we're just talking about, thinking about the wonders of the planet, thinking about the impact of humans so far in our explosive growth in the 20th century, I wrote that perhaps earth scientists of the future will name this post-Holocene era for its formative element for us, because we're kind of in charge in certain ways, you know, which is hubristic at the same time.

Yes, he is.

So there's a week of this stuff.

And...

The meeting was kicked off by, I wrote about it, Cardinal Maradiaga, who is, I think, from El Salvador.
