Climate Curious

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 open letter to Tristan Harris on saving the world.

New! An important essay: Ninety Nine Percent of all Conversations about Climate are Wrong

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


Ninety Nine Percent of all Conversations about Climate are Wrong — if you know what ECS is, read this.
Climate Curious — this is the one that started everything. 285k views so far.
A Tribute to Hans Rosling — A piece breaking down the temperature record.
Global Warming for Dummies — this is a good document to start with if people would rather read. It has plenty of embedded videos.
Recent Scientific Work on Climate Change — technical papers, most of whom could not get published by major journals.
Watts Available, an excellent “do the math” summary by Willis Eschenbach
Climate Change: Is it Real and Important? — A response defending me from a misguided rebuttal to the first essay, written by some global-warming enthusiasts.
The work of Andy May, a retired petrophysicist — several very important essays and books on politics, data, and misdirection.
The Rational Climate eBook, by Patrice Poyet — everything in one place.
An Open Letter to the Heartland Institute — Why I think they are making things worse, not better.

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:
