“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge .. the world has suffered far less from ignorance than from pretensions to knowledge. It is not skeptics or explorers but fanatics and ideologues who menace decency and progress.”

This is a work-in-progress to investigate the validity of attempts by scientists to reconstruct past atmospheric CO2 concentrations using air recovered from ice sheets. This air is considered by some to remain virtually unchanged for the decades, centuries and millennia that it is "trapped" within bubbles that form in the ice as it is compressed. Geologist Professor Richard Alley has gone as far as referring to the ice-core record as the "Gold Standard" for determining past atmospheric CO2 content (see Appendix A, Note 1) but is it?.
