The Age of Sustainable Development

by Bryan Walker April 1, 2015

It is profoundly depressing to hear pundits and politicians talking about the prospects for economic growth with no reference to either equity or environmental constraints. In the case of New Zealand a “rock star” economy can apparently develop accompanied by dismaying levels of child poverty, excited expectations of new oil and gas discoveries which spell […]

Leyland and Carter: the rebuttal that isn’t and the hypocrisy that is

by Gareth March 25, 2015

Sciblogs editor Peter Griffin recently gave climate denial activists Bryan Leyland and Bob Carter a “right of reply” to my post pointing out the errors and inconsistencies in a Dominion Post op-ed penned by the pair. Griffin took this action because of vociferous complaints from Leyland, who took offence at my discussion of his expertise […]

Climate Shock

by Bryan Walker March 12, 2015

Uncertainties attend the predictions of climate science, as the scientists themselves are careful to acknowledge. Reluctant policy makers use this uncertainty to support a “wait and see” response to climate change. Prominent American economists Gernot Wagner and Martin Weitzman in their recent book Climate Shock: The Economic Consequences of a Hotter Planet are scathing in […]

DomPost denier debacle: science has the last word

by Gareth March 10, 2015

The Dominion Post, which blotted its editorial copybook last week by publishing a factually incorrect and highly misleading opinion piece by climate denialists, has today published a heavyweight reply by three of NZ’s top climate scientists — David Wratt, Andy Reisinger and Jim Renwick1. Headed “Human role in climate change is clear”, the article is […]

25 ways the DomPost failed its readers by publishing Leyland and Carter’s climate crap

by Gareth March 6, 2015

The Dominion Post, the newspaper of record for New Zealand’s capital city, today gave great prominence to an opinion piece by high profile climate denialists Bob Carter and Bryan Leyland titled Hypothetical global warming: scepticism needed1. It’s a “Gish Gallop” of untruths, half-truths and misrepresentations — a piece so riddled with deliberate errors and gross […]

Antarctic ice going fast: Larsen C ice shelf primed for giant calving event

by Gareth March 2, 2015

The Larsen C ice shelf on the east coast of the Antarctic peninsula is primed for a giant iceberg calving event, and could be heading for total collapse — similar to the fate of the Larsen B ice shelf in 2002, according to scientists monitoring the ice. A huge crack (above: hover over the picture […]

Blink and its gone – spectacular time-lapse of ice retreat at Fox Glacier

by Gareth February 26, 2015

This spectacular time-lapse video1 captures the dramatic retreat of the Fox Glacier in Westland over the last year — 300 metres between January 2015 and January this year. As the ice retreats, the hillside becomes unstable and collapses down into the valley. To get a sense of the scale, you can see people watching from […]

The wrinkled retainer returns with a Peer-reviewed Peer

by Gareth January 22, 2015

There is much ado at Tannochbrae Manor, because the Laird has once again disproved global warming. One equation is all it takes! And an article in a new Chinese science journal with some friends, and lo! Take away that inappropriate and misapplied equation, remove the unjustifiable tripling and the climate “crisis” vanishes. You couldn’t make […]
