Simon Singh Wins Legal Battle

Good news for lovers of freedom of speech across the planet.

The British Chiropractic Association (BCA) this morning dropped its libel
claim against Dr Singh.

CO2 As A Greenhouse Gas


A greenhouse keeps an air volume warm mainly by enclosing it as fixed volume of air.  From that perspective, the term 'greenhouse gas' is a somewhat unfortunate choice of term.  But we seem to be stuck with it.

Obsolete books and web site pages continue to describe the atmosphere in terms of 'well-mixed gases'.  That is counterfactual.  Gases entering the atmosphere from whatever source can take a very long time indeed to become well distributed even even within a single hemisphere.  Or even within a single atmospheric layer.
