It’s been a long summer (not a hot one) for the The Climate Show, but Glenn, Gareth and John are back with a good show for the new year. Feature interview — and it’s a cracker — is with Californian computer scientist John Mashey, who has been digging deep into the networks of organised denial, tracking the flows of money and malpractice from plagiarism to zombie chairmen. Plus John Cook introduces his Debunking Handbook, a look at Arctic ice and it’s impact in European weather and a report calling for “dramatic action to avert a collapse of civilisation”.
