Lawrence Krauss relates the problems of publishing articles that challenge anthropogenic climate change (16 August, p 46). It seems to me that the problems arise from the habit of portraying the exposition of dissenting views as "a debate".rnA true debate allows each side to refute arguments made by the other, iteratively if necessary, until each assertion can be adequately sustained or debunked. If the arguments of the climate "sceptic" described by Krauss had been subjected to challenge by physicists, then no objective reader would have reached the conclusion that they were evidence against anthropogenic change.
