New Zealand parents often tell their children not to eat too many sweets. Our primary schools spend a lot of time talking about suitable diets. We do this because we have the long term interests of our children at heart.
I find the contrast between that and how we currently approach climate change disheartening and distressing and especially when I consider all the families I know who are now taking flying holidays with their children.
This is a really uncomfortable topic. But we have to talk about it, and do so urgently.
Anderson’s message is that although the Paris Agreement was a diplomatic triumph, it relies on speculative utopian technological fixes (bio-energy carbon capture and storage) in the future in order to reconcile the now extremely limited carbon budgets consistent with the desired 2C (and 1.5C) temperature limits with business-as-usual economics and politics. In other words, the Paris Agreement locks out the 2C target.
Why do I mention that? Because I want to run a ‘Kevin Anderson’ ruler over the New Zealand Government’s recently announced ratification of the Paris Agreement. To conduct a bare assessment of New Zealand’s emissions taking account that it is the cumulative emissions that determine warming. I want to ask the question ‘does the New Zealand ratification also lock out any policies for emissions reductions consistent with a fair share of a 2 degrees Celsius carbon budget?’
Geoff Simmons of the Morgan Foundation tells a good story about dodgy uncle Trev, fake bank notes and real moro bars while he fact-checks Paula Bennett on the integrity of the surplus emission units. It’s a real triple-dip!
Geoff Simmons and the Morgan Foundation have done it again! They have just released a sequel to ‘Climate Cheats’, the fantastically-named ‘Who’s the Real Cheat Here? Climate Cheats II: The Dozen Dirty Businesses’.
Simon Johnson (aka Mr February) reviews ‘Climate Cheats II’ and concludes that while it’s about time we had more transparency over Government and corporate shenanigans with emissions trading, we mustn’t forget that these are symptoms of the root problem – the uncapped design of the New Zealand emissions trading scheme.
Newsflash shock horror! The Morgan Foundation and Geoff “Wild-Shirt” Simmons have done it again. They have just released another tell-all critique of corporate emissions trading shenanigans, a sequel to the franchise they launched in April 2016 with the report Climate Cheats. As we know, ‘Cheats I’ outlined this sad course of events:
a ‘flood’ of low-cost and low-integrity Russian and Ukrainian emissions reduction units into the NZ emission unit market
which then crashed the domestic emission unit price
which allowed NZ emitters to meet emissions trading obligations for next to nothing
which allowed the Government to own large numbers of surplus (but dodgy) units
which meant Paula Bennett could claim ‘form over substance’ compliance with climate charge targets out to 2020
not withstanding the real increases in both gross and net NZ emissions of greenhouse gases.
The piece is riddled with errors and misrepresentations. Here’s a selection:
The “recent” paper on sea level rise de Lange and Leyland (dLL) reference in their first paragraph is from 2010! The latest Royal Society of NZ climate info was published last month, and is presumably what dLL meant to refer to.
The rise in sea level around NZ over the last 100 years is 17cm, not 14cm, according to the RSNZ (page 28 here).
dLL state that the current rate of sea level rise measured by satellite is 3.2 mm per year, with “indications of recent decline in the rate”. In fact it is 3.4mm per year, and shows no signs of any recent slowdown. If anything, there are hints of an acceleration in the underlying rate.
dLL claim that satellite measures are “about twice the tide gauge rate”. They’re not. They’re in good agreement. From Trends and acceleration in global and regional sea levels since 1807, Jevrejeva et al, Global and Planetary Change, 2013 (pdf)
There is an excellent agreement between the linear trends from GSL12 [latest tide gauge data] and satellite altimetry sea level since 1993, with rates of 3.1 ± 0.6 mm/yr and of 3.2 ± 0.4 mm/yr respectively.
The latest RSNZ projections are not “much more than anybody else” – they’re based on the IPCC’s AR5 and draw on the current literature. Larger projected future rises are widely used in planning overseas.
dLL state: “All the observational evidence indicates that the sea level is likely to rise 0.1 to 0.2 m by 2100.”This appears to be nothing more than wishful thinking. The current SLR rate gives 30cm plus by end of the century as a minimum.
There’s strong evidence of increased and increasing ice sheet mass loss in Greenland and Antarctica, which will add significantly to the amount of sea level rise by the end of the century. If we’re lucky, that might only be a metre. If we’re unlucky, it might be a great deal more.
If this were de Lange and Leyland’s only contribution to the debate on how communities should cope with sea level rise, it might be possible to shrug it off as a slapdash attempt at propaganda from a couple of people with a long history of climate denial. But de Lange is getting involved with the Christchurch community’s efforts to deal with this most challenging of issues.
Do Christchurch ratepayers really want to pay for advice from an “expert” who can’t get his facts right, and who is apparently happy to put his name to rubbish? The council should immediately ask for his withdrawal from the panel.
Future sea level rise is a certainty. Dealing with it is going to be challenging for any coastal community. We need a national framework that covers realistic assessments of local risk, and provides a process that allows communities to adapt as equitably as possible as their coastline changes. Trying to ignore or downplay the problem is only going to increase the costs faced by ratepayers and taxpayers in future years. If we allow the process to be contaminated by the input of propagandists we simply set ourselves up for greater losses.
