THE ‘greenhouse effect’ has been with us for so long that it is taken as ‘settled’ science in most quarters. However, as a new paper shows, there is much still to debate.
The author, William Kininmonth, is no bedroom blogger. As a former head of Australia’s National Climate Centre, he deserves careful and respectful attention.
