Till your well runs dry: NZ drought hits record levels

Australia may have had an extraordinary “Angry Summer“, but New Zealand’s been having a bit of a cracker too. Prolonged warm and sunny weather over much of the country has driven North Island soil moisture deficits to levels not seen for at least 70 years (see map at left). Official drought status — which means farmers are eligible for various forms of government assistance — has been declared in Northland, South Auckland, Coromandel, Bay of Plenty, Waikato, and Hawke’s Bay. The Manawatu and Rangitikei regions have also asked government for drought status. Most of the North Island is also subject to total fire bans — another first for this dusty summer. Preliminary estimates of economic losses are already heading towards $1 billion.

Stuff.co.nz noted the obvious climate connection:

Long, dry spells are forecast to double by 2040 as temperatures continue to rise and New Zealand heads towards a more Mediterranean climate.

Experts warn it could spell the end for farming as we know it and may cost the country billions of dollars in drought relief each year before practices are adjusted.

“This is historic,” said climate scientist Jim Salinger, who has calculated that the amount of rain needed for grass growth was the highest since records began. “It’s like comparing your income against expenditure in your cheque book. And we are in deficit.”

Recursive fraudery: Monckton goes mad in Australia

Christopher, Viscount Monckton of Brenchley’s tour of Australia must be going very badly, because the “high priest of climate scepticism” is indulging in another of his increasingly desperate displays of attention seeking behaviour. After giving a poorly attended lecture in Hobart last week, Monckton took umbrage at an article in the Sunday Tasmanian (on the web here) reporting the views of Tony Press, CEO of the University of Tasmania’s Antarctic Climate and Ecosystems Co-operative Research Centre, who was not impressed by Monckton’s efforts. In response, Monckton has thrown his toys out of his fossil fuel funded pram, and called for the University of Tasmania to fire Press. Here’s the last paragraph from his typically pompous and ludicrous letter [pdf] to the Vice Chancellor:

On any view, Press is not a fit and proper person to be employed in any capacity at the University of Tasmania. I hope that the University will investigate his misconduct and fraud and will dismiss him forthwith.

Connoisseurs of Monckton’s antics will note that this is a well established pattern of behaviour. Remember when he took exception to the comprehensive dismantling of one of his lectures by John Abraham, and tried to get him fired? Nothing came of that threat — except that Abraham was motivated to become more active in countering climate crank nonsense wherever it appears.

Tackling agricultural emissions: the NZ story

In this guest post, Josh Pemberton, an intern at Motu Economic and Public Policy Research, describes the Ag Dialogue exercise Motu ran last year. This interesting and thought-provoking short film exploring what reducing emissions really means for New Zealand’s farming communities was one result.

New Zealand is, in many ways, an unusual country. We pride ourselves on punching above our weight in international relations and sport; but we cherish the fact that we are a small and uncrowded nation, happily occupying our own little corner of the earth. We admire our rugby and Olympic heroes yet our national symbols are relatively innocuous: an upside down fern frond (the upper side of a silver fern is, of course, green) and a flightless, nocturnal bird. It must say something about our mentality that in recent years we treated an unshorn sheep like a national celebrity, and that a shortage of our favourite spread triggered panic-buying and created ongoing headlines.

Something else which is unusual about New Zealand — considering that we’re a developed nation — is that agriculture is responsible for almost half of our greenhouse gas emissions. Agriculture is, of course, vitally important to our economy – providing jobs and crucial export dollars. These two factors together give rise to a tension which can inhibit conversation about the effect of agriculture on the environment. It’s easy to end up with “naïve greenies” and “conservative farmers” (as they may perceive each other to be) talking past one another, and missing an opportunity to make real progress.

In the past two years, Motu Research has sought to increase the quality of the conversations that people are having on this topic. Motu set up and ran the Ag Dialogue group, bringing together farmers, scientists, iwi, government representatives and other experts to talk through issues around greenhouse gas emissions. There was no specific output in mind, although the Dialogue did catalyse a significant amount of research by Motu economists. The Dialogue also led Motu to release The New Zealand Farming Story: Tackling Agricultural Emissions, the short film embedded above.

Messages from a sizzling continent: Salinger on the Aussie heatwave

This op-ed by climate scientist Jim Salinger first appeared in print editions of the New Zealand Herald last Tuesday.

Global warming is not a phenomenon for future generations to deal with: it has arrived. And more frequent heat waves and climate extremes are part of this phenomenon. As I watch from my summer roost in northern New South Wales, the somewhat unprecedented heat is searing the Australian continent making it tinder dry with fires springing up everywhere. These raise some pertinent lessons on climate and risk management for New Zealand.

Firstly let’s look at some figures and ask the question of what are the climate mechanisms behind the heat waves.

Climate of complacency: NZ Herald lazy and irresponsible

Saturday’s New Zealand Herald carried an astonishing editorial on climate change — remarkable enough to prompt me to tweet that it was “crass, complacent and so very wrong“, despite it being ostensibly in support of action on climate change. The piece begins by riffing on the wildfires in Australia, before observing:

With Australia having its two hottest days on record this week, and New Zealand enjoying a hot summer, it feels like climate change has arrived. But most scientists are wary about attributing any particular weather to global warming. To cite this summer as evidence would enable sceptics to recall last January’s washout.

“Most scientists” are being anything but wary about discussing the link between the Aussie heatwave and climate change. Australia’s Climate Commission released a special report on the heatwave at the end of last week. Here are the first three “key points” from the report:

  • The length, extent and severity of the current Australian heatwave is unprecedented in the measurement record.
  • Although Australia has always had heatwaves, hot days and bushfires, climate change is increasing the risk of more frequent and longer heatwaves and more extreme hot days, as well as exacerbating bushfire conditions.
  • Climate change has contributed to making the current extreme heat conditions and bushfires worse.

Straightforward enough, you might think. Climate change is making the heat and fires worse. But if the Herald editorial writer might be forgiven for missing a major report from the Australian body tasked with informing that nation about the realities of climate change, he or she cannot be forgiven for the astonishing complacency evident in the next few paragraphs.
