Kiwiblog kobblers

New Zealand’s leading right wing blogger, National Party spinmeister and opinion poll guru David Farrar, this morning allowed himself the luxury of a rant about the New Zealand Herald‘s coverage of a new paper on sea level during the late Pliocene. In a post teasingly titled “Alarmist bullshit“, he manages to demonstrate his rudimentary grasp of the facts, misunderstands the real story behind the new research, and ends up shooting himself in the foot. Here’s David in full flow:

Anyone who thinks public policy today should be based on a forecast of what the climate might be in 5,000 years is nuts. Look at how the world has changed in just 100 years let alone hundreds or thousands. Hell in 1,000 years we may be living on Mars.

The Herald should be ashamed for saying that the projected increase could “dramatically transform” our coastal boundaries. A change over 1,000 years+ is not dramatic. It’s like saying the separation of Gondwana was dramatic.

20 metres is a lot of sea level rise. Here’s what 20 metres would mean for my nearest city, poor old quake-plagued Christchurch, courtesy of the Firetree sea level rise calculator. The central business district is under water, the new shoreline well to the west. At a rough guess, I’d say 80% of the city is flooded, and Banks Peninsula is an island once more.

I think that can be reasonably described as a dramatic transformation of the South Island coastline, even if it does take 1,000 years to happen. DPF might like to note that coping with two metres per century sea level rise is nobody’s picnic. But his misunderstanding runs deeper…

Unstoppable waves of innovation in the Waikato?

A pleasant surprise this morning to see across the front page of the Waikato Times the headline “Waikato’s plan to harvest sunlight”.  The article reports that lines company WEL Networks has been evaluating photovoltaic cells and is now investigating the feasibility of solar power production in the Waikato region.

Commercial viability is the determining factor. It’s the dramatic fall in the cost of photovoltaic cells which has caused WEL Network’s investigation. CEO Julian Elder said that the low price of the cells, compared with where they were a few months ago, made solar power stations affordable in New Zealand. He said that in the space of a few months the return on investment had gone from about half a century to under 10 years.

We are looking at the whole range, from 1-2 kilowatt units on a house, up to the thousands of kilowatts for a large-scale pilot,” Dr Elder said.

He said it was not a case of if they built such power stations but a matter of when.

The wrong road to take

It’s difficult not to become repetitive when blogging about climate change. The basic science is well-established. The dangers global warming poses to human society are clear and in some places present. The solutions lie with drastically cutting the level of greenhouse gas emissions and adapting to changes already unavoidable.  The mitigation solution in particular continues to be resisted by vested interests and their political allies. I’m conscious of having expressed each of these facts many times over in a variety of forms over the past three years. And now I’m about to repeat myself within a month of last writing about the contradiction in New Zealand government thinking.

Signs of things to come: Salinger on Australian heatwaves

Climate change is happening now and Australia is in the firing line says Jim Salinger in this guest post. This article first appeared in the Dominion Post.

As I watch from my summer subtropical perch in Brisbane, Queensland, the somewhat unprecedented rains that deluged parts of Australia during the summer of 2010/11 have been replaced by sizzling heat waves this summer. 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.

For December 2011 the Bureau of Meteorology figures show that the highest temperatures of the year occurred in the third Australian heat wave of the year. This affected the Pilbara region in the north west of Western Australia. Multiple sites broke the previous Western Australian December record of 48.8ºC on December 26, 1986 with Roebourne recording 49.4ºC on December 21, Onslow Airport recording 49.2ºC on the 22nd and Learmonth 48.9ºC on the 23rd. Roebourne’s 49.4ºC was the highest temperature recorded in Australia since 1998.

This month incessant heat has struck the interior with daytime highs soaring to the mid forties. As I pen this there are a few more days of this heat wave left with temperatures averaging between 35ºC and 40ºC in central Australia. Places have been recording daily lows of 30ºC and daily highs of close to 45ºC. Mean temperatures have been running over 6ºC above average.

Doublethink: doubleplus ungood

What do New Zealand government members really think about the chasm between their claims on the one hand to be addressing climate change and their insistence on the other that we must take every opportunity to expand our fossil fuel mining industry? I listened to a recent Radio New Zealand interview with Tim Groser, the Minister responsible for international climate change negotiations, in which he discussed the outcome of the Durban conference. He sounded committed to the reduction of greenhouse gas emissions. He was respectful of the science. He affirmed that the progress so far made was inadequate, but thought it possible that Durban might turn out to have been a critical turning point by getting all the big emitting countries on the mitigation bus. He sometimes sounded the “real world” theme, but not to the extent of suggesting that the whole process was doomed to failure. He was positive about renewable energy potential. One might disagree with some of his perspectives, but there was no suggestion that he was not serious about the need for the world to move to low-carbon economies.

Yet back in New Zealand Groser is a Minister in a government which is planning to increase the exploration and exploitation of fossil fuels, claiming that they offer immense financial benefits that we would be foolish to forego. These fuels will release greenhouse gases into the atmosphere either in the countries to which they are exported or here. When pressed on the issue the excuses offered include that emissions in other countries are the responsibility of the users of the fuels, not the suppliers, that within New Zealand our Emissions Trading Scheme will somehow result in the satisfactory offsetting of the harm done by the emissions, and that if we don’t mine fossil fuels others will and we will suffer an unfair economic disadvantage.

I find it impossible to mentally inhabit these two worlds simultaneously. A world in which we are working sincerely to a drastic reduction in greenhouse gas emissions, and a world in which we are vigorously pursuing the extraction of every last bit of fossil fuel we can locate. Am I lacking mental agility?  Or is there doublethink going on in government?
