The Header Chart:
The chart on display in the header shows the last 6,000 years of temperature data from the Penny Ice Cap. I got the file from the NOAA website.
The file contains data for the past 11,000+ years. I only used the last 6,000 years for simplicity of the header chart. The chart shows the stable isotope data.
The Book: The Inconvenient Skeptic
I am building a series of pages that contains the critical graphics and data sources from the book. They will be grouped a couple of chapters at a time. Please contact if there are any questions on the sources used for the book. This will probably take a while to get completed, so please be patient.
