The Climate Show #20: the boys are back (on Tuvalu)

by Gareth October 20, 2011

Battling against rural broadband that resembled digital molasses (or the bunker oil being pumped out of the Rena), Gareth returns to NZ and joins Glenn Williams and John Cook to discuss drought in Tuvalu, the El Niño Southern Oscillation (ENSO), floods and sea level falls, ocean cooling (that isn’t), solar towers of power and much, [...]

So many lies – and the liar who tells them

by Gareth July 4, 2011

A headline caught my attention yesterday: Shock News: Disgraced Climategate Scientist Made Top UN Weatherman. It popped up all over the crank web. Climate Realists seemed to get it first, then Morano’s Climate Depot, and soon it was at the gloriously titled “CO2 Insanity“, ICECAP.us and many, many more. Here’s the intro and first sentence: [...]

Fools gold: cranks can’t count

by Gareth February 9, 2011

I don’t know whether to laugh or cry. 14 months on from the start of the Treadgold/Climate “Science” Coalition/ACT campaign to cast doubt on the long term New Zealand temperature record, after parliamentary questions, much mud slinging at Jim Salinger and NIWA, legal action, and the expensive and time-wasting reconstruction of a temperature series that’s [...]

The Climate Show #6: Monckton and the iron in the ocean

by Gareth February 3, 2011
