John Christy's Opinions

Global Warming

Is global warming caused primarily by humans?

Neutral

Atmospheric carbon dioxide continues to increase due to the undisputed benefits that carbon-based energy brings to humanity. This increase will have some climate impact through CO2's radiation properties. However, fundamental knowledge is meagre here, and our own research indicates that alarming changes in the key observations are not occurring.

Climatology

Is the IPCC objective?

Disagree

You dare not be thought of as "one who does not know"; hence we may succumb to the pressure to be perceived as "one who knows". This leads, in my opinion, to an overstatement of confidence in the published findings and to a ready acceptance of the views of anointed authorities. Scepticism, a hallmark of science, is frowned upon. I suspect the IPCC bureaucracy cringes whenever I'm identified as an IPCC Lead Author.
