Guardian environment editor John Vidal gives the DenierChaps convening in Copenhagen the kind of attention they deserve in his piece today.

He had the temerity to stand up in the room and ask:

“I would like to know whether you or anyone in this room has been to the Himalayas, or to the Sunderbans, or to the villages that are now drowning near Chittagong in Bangladesh, where temperatures are being recorded 4C above normal, where respected scientists are finding significant sea level rises, where cyclones are more frequent and intense? Have any of you tried to find out for yourself what is going on there?”

Through the whistling and abuse that followed, you could only conclude that the answer was no.
