Long stories short, here’s the top six news items of note in climate news for Aotearoa-NZ this week, and a discussion above between Bernard Hickey and The Kākā’s climate correspondent Cathrine Dyer:
The month of August was 1.49˚C warmer than pre-industrial levels, tying with 2023 for the warmest August ever, according to the EU’s Copernicus climate dataset. This is despite the absence of El Niño’s heat amplifying effects that were present last year.
The Government’s National Land Transport Programme (NLTP) plans on executing a U-turn, taking us back in time to a car-dependent past, according to University of Auckland academic Timothy Welch in The Conversation. The worst thing, he suggests, is that most of the $8 billion in planned spending will go on planning, design and preparatory work, rather than actual construction.
Debate about whether ‘climate intellectuals’ should focus on disinformation and misinformation underestimates the political versus the technical obstacles to decarbonisation, according Aaron Regunberg in the Jacobin. The critique was ‘story of the week’ on the website skepticalscience.com, who argue that systematic climate mitigation is an inherently political matter.
The population effects of climate displacement are causing increasing concern in the US. “When multiple cataclysmic disasters strike one region in quick succession, climate change-driven phenomena called “compounding events,” they create overlapping ripples of displacement, making the movement that much harder to track. If it was tracked in real time, local officials would see disturbing trends,” according to this gnarly tale in The Grist.
Glaciologists are in a race to collect ancient virus specimens from fast-melting glaciers after finding 1,700 mostly new-to-science ones in Tibet. Meanwhile other scientists are coming up with massive geo-engineering plans to try to slow the collapse of the so-called Doomsday Glacier in Antarctica.
The chart of the week is putting the terrors into gulf coast communities in the US.

1. A dead heat in August
August 2024 has come in at +1.49˚C above pre-industrial levels, tying with 2023 for the warmest August on record, according to the Copernicus ECMWF dataset.
This means 2024 is virtually certain to break the record for hottest year ever, according to climate scientist Zeke Hausfather.

While temperatures in August 2023 were in the grip of an El Niño, the El Niño Southern Oscillation (ENSO) has now been neutral for several months. That should have resulted in temperatures dropping through the back half of 2024 compared to the El Niño elevated 2023. The size of the heat anomaly has been declining, but the effect is more muted than it should be. The decline is more visible in sea surface temperatures – it helps to look at the two side-by-side:

Some countries have been sweltering through record-breaking temperatures. Japan’s hottest summer ever has produced thousands of “extreme heat” events.
“The average temperature in June, July and August was 1.76C higher than the average recorded between 1991 and 2020, the Japan meteorological agency said, according to Kyodo news agency.
It was the hottest summer since comparable records were first kept in 1898 and tied the record set in 2023, the agency said. Japan has recorded 8,821 instances of “extreme heat” – a temperature of 35C or higher – so far this year, easily beating the previous record of 6,692 set in 2023, it added.” Source: The Guardian
Large swathes of China also experienced their hottest August ever. China has a three-tier warning system for temperatures and was issuing warnings at the highest tier (above 40˚C) for 12 consecutive days in late August.
Meantime Australia, where it is meant to still be winter, was recording temperatures in excess of 40˚C in a series of unusual winter heatwaves. It was not just the extreme temperature but the scale:
“Bureau of Meteorology maps showed a giant mass of extreme heat from near Brisbane in the east to the interior of Western Australia – a distance of about 3700km.
Data on Wednesday showed 48% of the country experienced maximum temperatures in the hottest 1% on record for August.
Nadine D’Argent, a climatology specialist at the bureau, said there were several “wow moments” as the temperature data came in.
“Seeing 40C in August is quite rare. We generally don’t see that until late September but we’ve had 16 instances where temperatures have gone above 40C.”” Source: The Guardian
2. The land transport U-turn taking us back to the past
The Government’s evidence-free National Land Transport Programme (NLTP) plans on executing a U-turn and taking us back to a car-dependent past, according to University of Auckland academic Timothy Welch in The Conversation.
The problem – well, one of the problems - is that our driver, Simeon Brown, hasn’t looked over his shoulder for following traffic, or at the dashboard for useful statistics, before attempting to execute the manoeuvre.
The $8 billion price tag, Welch points out, won’t actually build anything for decades. The massive price tag is for planning, design and preparatory work (presumably headed for the pockets of some much-maligned contractors) rather than actual construction.
“The approach effectively commits billions in taxpayer dollars to preparatory work without delivering any tangible infrastructure improvements. New Zealanders will likely find themselves stuck in worsening traffic, waiting for highways that may never materialise.
These projects could easily be sidelined by future budget constraints or changing political priorities. A growing recognition of induced demand – where new roads generate more traffic rather than alleviate congestion – and the looming challenges of climate change risk these carbon-intensive projects being obsolete before they even begin.
Meanwhile, projects that could address far more severe congestion in the main cities are being cut back or indefinitely postponed.” Source: The Conversation.
On the one hand, there is hope that these backward looking, demand-inducing “asphalt aspirations” will melt before our eyes, with some good sense materialising before they do. On the other hand, nobody gets what they want anymore (credit to Marlon Williams Music). Read it, or sing it, and weep.
3. Fighting Climate disinformation the urgent priority
A debate about the value of focusing effort on fighting climate disinformation (and misinformation) has been bubbling quietly in climate circles this week after an article by Holly Buck appeared in Jacobin, followed swiftly by a powerful critique from Aaron Regunberg.
Buck claims that the amount of attention currently being placed on climate misinformation is creating a sizeable distraction, particularly in the US, from the funding that is landing on the ground courtesy of Biden’s Inflation Reduction Act (IRA).
‘Climate intellectuals’ ought to be focusing on efforts on the ground, knitting together the people working on resilience, and creating a narrative story that fuels motivation, Buck claims, instead of waging a “an information war focused on uncovering what Big Oil knew and policing speech.” Her assumption is that such climate disinformation does little to curtail climate action.
But Regunburg suggests this underestimates the political versus the technical obstacles to decarbonisation.
“The fossil fuel industry remains the biggest obstacle to the clean-energy transition, and climate disinformation remains its most potent tool. It is very much in Big Oil’s interest for climate advocates to, as Buck suggests, stop “obsessing over climate disinformation.” But we should resist such suggestions. The climate movement can walk and chew gum at the same time; we can work hard to fight climate disinformation while using other on-the-ground organizing frames when they’re more appropriate. Indeed, given the urgent tipping point deadlines the climate crisis imposes on us, we don’t have time for anything less.”
The extent to which public finances, including in Biden’s IRA, are being directed toward fossil-fuel backed projects that are based on a layer cake of misinformation is unignorable. It could very well succeed in driving global emissions into overshoot and diverting global financing toward speculative technologies that may never work at the scale required.
The website skepticalscience.com covered the debate as their ‘story of the week’, saying that “Downplaying or ignoring intentional deceit delivered on an industrial scale is a bit like thinking that wishing hard enough to stay dry is as good as an umbrella when encountering a rainstorm. Climate remedy will happen via effective public policy, public policy is an outcome of politics and hence systematic climate mitigation is an inherently political matter.”
4. Disturbing trends in climate displacement
“Those who remained did so for one of two reasons: They could afford to stay, or they couldn’t afford to leave.”
For many of us, the concept of climate displacement or migration is something we assume will happen to other people, mostly in developing countries or low-lying island nations. We also fail to recognise the immobility of those who don’t or can’t migrate as an adaptative response to increasing risks.
The Grist gives us a gnarly tale this week about the largely under-estimated and under-reported extent of climate displacement already occurring in the US. They ask whether the US census, undertaken once per decade and which then informs district lines, congressional representation, and the distribution of federal and state funding, can keep up.
“‘After Hurricane Katrina in 2005, for example, New Orleans knocked down much of its affordable housing, damaged during the hurricane, deeming it a safety hazard. The new buildings that went up were more expensive, and the new construction very quickly gentrified neighborhoods, forcing even more people out in a second, extended wave of displacement. New Orleans absolutely became a city that was whiter and wealthier than it was beforehand,’ said Daniel Aldrich, a professor of political science at Northeastern University. But it was difficult to capture those changes as they were happening, Aldrich said, because the initial population shifts occurred so quickly and because many of the people who left the city were renters.” Source: The Grist
The population effects of the 2010 and 2011 earthquakes in Christchurch offer some local insight into the way post-disaster displacement can change a city or region. Christchurch’s population composition changed in terms of gender, age and ethnicity with both temporary and more lasting effects.
5. Gotta catch ‘em all: Collecting ancient viruses
Scientists have uncovered more than 1,700 ancient viruses from a glacier in Tibet, most of them not previously known to science. They date back as far as 41,000 years and differ markedly between colder and warmer eras, shedding light on how life evolved through previous climate shifts. The scientists are now in a race to collect as many more as they can before the glaciers melt.
Also on the subject of glaciers: the Doomsday or Thwaites Glacier is back in the news. Fears that the glacier may be on the verge of total collapse were somewhat allayed by a new modelling study published last week suggesting that at least one possible trigger was less likely than previously thought. However, the question of whether the glacier has already passed the point of no return, and entered a death spiral remain. The latest suggestion is that geo-engineering, in the form of a massive underwater curtain, up to fifty miles across, could be erected to seal off the Thwaites Glacier and adjacent Pine Island Glacier, from the remorseless Antarctic current.
“Opponents of the plans, including many glaciologists, say such outlandish proposals are a dangerous diversion from the real task of mitigating climate change by curbing carbon emissions. But advocates say the two glaciers can’t wait. “We can’t mitigate our way out of this,” says Moore. “We need other tools.”” Source: YaleEnvironment360
