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. I now teach a climate-science master class online. This advanced class on climate science consists of about 18 hours of self-paced video material and weekly discussion sessions amounting to over 60 hours of recorded video. We also have special events and live guest speakers. We have Q&A on the platform so you can ask a question any time. We discuss the latest climate news, papers, research, and developments. You can also meet and collaborate with other students.

I was worried it would be too advanced for my level, but the concepts so far are easily understandable. – Rachel

All discussions are recorded, so you can be present for the meetings or not and still see everything any time you like.

Guest speakers have talked with us and answered questions on:

  • The scientific method

  • The Pacific Decadal Oscillation

  • Renewable energy economics

  • Solar science and cosmic rays

  • Climate science education

  • CO2 research

  • Radiative transfer of energy

  • Mass extinction events

  • Ice-core data analysis

You get a full one-year membership for $150 or £115.

Testimonials and a sample of the videos are below.

Fascinating, interesting and brilliantly delivered masterclasses on climate science - unmissable stuff. – Michael

 Besides the class, there are many resources here. 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.
