Climate change challengers have arguments worth considering

IN his letter (March 31), Dr Phillip Michael thinks my letter (March 25) on climate change did “a disservice to mankind and planet earth”.

He feels I would not have been “dismissive” of the Intergovernmental Panel on Climate Change (IPCC) had I “bothered to familiarise” myself with its history and work.

He assures us its members are not “a few mad scientists with an axe to grind”, but “top scientists”, “eminent specialists” and “learned people”.
