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

by Gareth February 3, 2011

A very wide ranging Climate Show this week, with Dr Philip Boyd of NIWA and Otago University explaining why fertilising the oceans to soak up more carbon is not likely to be our “get out of jail free” card, John Cook of Skeptical Science introducing the new Monckton Myths section of the site, plus interesting [...]

by Gareth January 6, 2011

2010 was the fifth warmest year in the long term New Zealand record, and December the third warmest, according to figures released by NIWA and analysis by Jim Salinger.

A Christmas cracker for the cranks

by Gareth December 22, 2010

The National Institute for Water and Atmospheric Research (NIWA) released details of its recalculated New Zealand temperature series last week and in the last couple of days Richard Treagold and the Climate “Science” Coalition have issued statements in reply. And what a contrast they provide: Bryan Leyland for the NZ C”S”C is all bluster, demanding [...]

NIWA’s new NZ temperature series: plus ça change…

by Gareth December 16, 2010

Earlier this afternoon NIWA released its recalculated NZ temperature record [full report], and as expected the changes from the “old” seven station series are more or less negligible. The trend over the last 100 years is identical, 0.91ºC per century, as the graph above shows. There are minor differences in some years, and larger ones [...]

NZ glaciers holding their own (just)

by Gareth November 9, 2010

New Zealand’s glaciers just about held their own over last summer, showing a very slight gain in mass on average according to NIWA’s annual end of summer snowline survey, released today. The Park Pass glacier (above) in the Mt Aspiring National Park between the Hollyford Valley and the head of Lake Wakatipu (map) is one [...]

I’ve been wrong before

by Gareth October 15, 2010

It appears that the crank pantheon has a new hero: John O’Sullivan — the “world’s most popular Internet writer on the greenhouse gas theory” and the man unafraid of getting everything wrong. The last time we encountered him, he was getting everything wrong about the New Zealand Climate “Science” Coalition’s attempt to take NIWA to [...]

NIWA v Cranks 4: Shoot out at the fantasy factory

by Gareth October 9, 2010

Earlier today a Hot Topic reader drew my attention to this article: Legal Defeat For Global Warming In Kiwigate Scandal, which Nigella Lawson’s father’s secretly-funded Global Warming Policy Foundation chose to feature on its web site. What’s “Kiwigate”, he wanted to know? Turns out it’s the NIWA versus NZ Climate “Science” Education Trust court case, [...]

Friday’s dust

by Gareth August 20, 2010

The weekend’s coming, and so I’m clearing out some of the stuff that’s cluttering up my web browser. NIWA recently posted an excellent explanation of the carbon/greenhouse gas relationship in pastoral agriculture, taken from the July issue of their magazine, Water & Atmosphere: Why isn’t grass in, methane out, carbon neutral? Click on the image [...]

NIWA v cranks 3: the economics of truthiness

by Gareth August 18, 2010

Bryan Leyland’s dissembling about the funding of the NZ Climate Science Coalition under direct questioning from Sean Plunkett on Monday morning’s Morning Report on RNZ National — he repeatedly asserted his ignorance of financial matters, directing Plunkett to Terry Dunleavy — puts him in an awkward position. Leyland is a trustee of the NZ Climate [...]
