My name is David Siegel. I’ve been studying environmental science since the mid-1980s and published my first book on climate change in 1991. I’ve made dozens of videos and written many essays, some of which are on this site. I curate two lists — PhD scientists who believe more CO2 would be better, and a list of peer-reviewed papers.
In 2024/5 I taught an online class. I no longer have time to teach. You can find much of the material below.

Sample class: Renewables
A good place to go next is to see more videos. Advanced science types can take the climate quiz or see the peer-reviewed papers. If you know any true climate alarmists, ask them to answer a few hard questions.
The best book for ordinary mortals on climate is Solving the Climate Puzzle, by Javier Vinos. The most authoritative and important book for technical types is Climate of the Past, Present, and Future: A Scientific Debate, by Javier Vinos. Watch his presentations on the videos page.
