Last week, Shell's climate change adviser David Hone issued a complaint that I had appeared on the BBC to discuss the Fifth Assessment Report.
[The BBC] explained the issue quite well, but then offered two contrasting views of the science. One was an interview with a leading UK climate scientist who is also a contributing author to the IPCC report, the other was with a blogger who lacks credible credentials and objectivity on the issue.
If only I could aspire to match Mr Hone's credentials (he is a chemical engineer) and objectivity (he is chairman of the International Emissions Trading Association).
Do these people have no sense of how foolish they make themselves look?
