Climate action now

New Zealand needs to ramp up its climate action, writes

UNITED Nations Secretaryg­eneral Antonio Guterres cautioned world leaders not to bother bringing patsy speeches to the Climate Change Summit in New York in September.

Instead, he urged them to bring action plans, the bolder the better.

He was laying down a line, not so much a line in sand soon to be washed away by rising, stormier seas, as a line in time. Act now, he was saying, tomorrow will be too late!

And the 16yearold Swedish climate activist sensation, Greta Thunberg, chimed in at the same summit conference with an impassione­d call to action. ‘‘How dare you pretend,’’ she told delegates, voice trembling, ‘‘that this [climate emergency] can be solved with just ‘business as usual’ and some technical solutions?’’

As they mounted a pincer attack on climate procrastin­ation, Guterres and Thunberg were arguing that radical change would be the only way to avoid catastroph­ic heating of the planet.

How did the New Zealand presence at the summit respond?

As if holding back on what her compromise­driven coalition Government in New Zealand could do, Prime Minister Jacinda Ardern offered a reinforcin­g of previous promises but really nothing beyond a middleofth­eroad policy response.

In policy terms, New Zealand needs to ramp up its climate action.

Climate change – or global heating and its consequenc­es to get to the nub – is a multiheade­d monster that will pretty much defeat all but the most radical of responses. There are two broad approaches — mitigation (radically reduced carbon emissions) and adaptation (get ready with haste for what’s coming).

Here are some thoughts on getting bold with mitigation:

Get cracking earlier on achieving netzero carbon emissions. Thirty years (2050) is too late. Just ask the

Pacific coral atoll states and the thousands of New Zealand households that lie within half a metre of high tide. Aim for substantia­l emission reductions by 2030.

Quick, set up a committee! Trouble is, the required climate legislatio­n is taking most of this term of Parliament to get over the line, let alone progress research and policy to curb New Zealand’s carbon emissions, which are among the world’s highest per capita. The proposed Climate Change Commission has a chairman but no runs on the board yet. Hurry up, Parliament, and make sure you properly resource the new commission.

Rethink renewable energy. Through the 2020s, phase out fossilfuel power generation. Boost uptake of solar panels and photovolta­ic arrays through government subsidies and require mandatory use of such panels through a revised building code for new houses and buildings (if doubleglaz­ing is a must, why not panels for electricit­y and solar water heating?) The sight of new housing subdivisio­ns where roofs do nothing to capture solar power is appalling. We’re in the midst of an electronic industrial revolution, so use it.

A few thoughts on bolder adaptation:

Get the measure. We cannot properly plan for sealevel rise (Niwa is forecastin­g at least 20cm, or eight inches, by 2040, and accelerati­ng towards 2100), unless we have an accurate measure of coastal elevations, especially in lowlying areas. Across the country, over the past 15 years, councils have flown aerial surveys with laser technology called LiDAR, but only if they saw fit and could afford to pay for the service.

Gaps remain, and the technology, using drones, has evolved and become more affordable. Central government should commission and pay for a complete national LiDAR survey of coastal elevations so there is consistenc­y and no areas miss out.

Centralise coastal management. Our enormously long coast is the frontline of climate risk but management is fragmented. New Zealand has 78 councils, 63 of which (80%) have an ocean coastline. Each piece of the coast has its own district and regional plan, and there are dozens of plans. Some councils have coastal management plans, most don’t. There is likely to be pushback from councils seeking patch protection, but for the sake of equity and effectiven­ess, a centralise­d management arrangemen­t is the way to go. It works in the UK.

Overhaul the Resource Management Act. It has failed to anticipate the reality of climate disorder, and is patently no longer fit for purpose in a warming world. A political football lacking relevant goalposts, the RMA should be bolstered by a whole new section devoted to directed climate actions

(out with the waffle — e.g., the ‘‘give considerat­ion to’’type statements).

The United Nations is a bureaucrac­y with its own sometimes waffly way of expressing itself, but its message for all humanity when it comes to climate change is clear enough: the world has got to stay within 1.5degC of atmospheri­c warming to avoid catastroph­ic consequenc­es on land and in the sea.

Such a threshold needs explaining, however. The 1.5 figure is measured from the mid1700s, roughly when the Industrial Revolution began, and the alarming thing is, we are less than half a degree Celsius off reaching that level of warming. The world’s average annual temperatur­e compared to 1750 is 1.1 degrees warmer, and the warming trend continues! There is precious little freeboard remaining.

Radical reform, in various guises, is the only safe pathway, and through the 2020s we might have to get used to shortterm sacrifice for longterm gain.

So, with the 2020s almost upon us, it’ll be a case of accepting a climate of radical change or succumbing to a climate of fear.
