When Benny Peiser responded to UK chief scientist David King on openDemocracy earlier this week, it provoked a sharp response from Charlie Kronick of Greenpeace.
Benny Peiser came back with a determined riposte.
Now William Connelley makes a detailed analysis of Benny Peiser's arguments.
The issues here have been explored elsewhere, including William Connelley's own blog Stoat. (Connelley is also a contributor to RealClimate.org.)
Some, including writer and activist Paul Kingsnorth, argue that it's not worth going over this ground again.
My view is that in a debate for a worldwide readership, many of whom many not have come to these issues before, it is worth exploring these differences.
