My work on climate change

My name is David Siegel. I wrote my first book on climate change in 1991. Among other things, I write about science, climate, and energy policy. I am not paid by any outside groups to do this. More than 500,000 people have seen my work. This page contains instructional material on the climate debate. I also have a daily news page at

New! An important essay:

The main work is this one-hour video presenting climate data:


— this is the one that started everything. 285k views so far.
— A piece breaking down the temperature record.
— this is a good document to start with if people would rather read. It has plenty of embedded videos.
— Why I think they are making things worse, not better.
— technical papers, most of whom could not get published by major journals.
, an excellent “do the math” summary by Willis Eschenbach
— A response defending me from a misguided rebuttal to the first essay, written by some global-warming enthusiasts.
— LinkedIn short piece describing my experience after publishing the essay.
The work of Andy May, a retired petrophysicist — several very important essays and books on politics, data, and misdirection.

Individual Chapters from the Big Video — for people doing research, the chapters are available separately. They are a bit less edited than in the big video.

From Tony Heller, we can see the raw thermometer data from all 1,200 stations in the Historical Climate Network:

Note: stations that have become urbanized will show a gradual warming trend as a result of encroaching civilization. What trends do you see in this data?

The following animation of earth for the past 4.5 billion years is worth watching. Note the correlation between temperature and CO2:
