The world is on course to overshoot the critical 1.5°C global warming threshold, with a new United Nations assessment warning even the most optimistic pathway would see temperatures temporarily reach around 1.8°C above pre-industrial levels — prompting Greenpeace to accuse the New Zealand Government of moving in precisely the wrong direction.
Greenpeace Aotearoa spokesperson Gen Toop says the latest findings reinforce the urgency of rapidly reducing climate pollution and minimising both the scale and duration of any temperature overshoot.
The organisation argues every additional fraction of a degree matters because climate risks intensify as temperatures rise — from extreme weather and ecosystem destruction to rising seas, food insecurity, pressure on freshwater and growing economic damage.
For Aotearoa, the warning also raises significant questions for Māori communities whose whenua, marae, wāhi tapu, mahinga kai and coastal settlements are already exposed to a changing climate.
Even the best scenario goes beyond 1.5°C
The UN findings paint an increasingly difficult picture for the landmark target at the heart of the Paris Agreement.
According to the report cited by Greenpeace, even under the most optimistic scenario global temperatures are expected to temporarily peak at around 1.8°C above pre-industrial levels before declining.
Less optimistic scenarios would see temperatures climb further.
That makes the difference between temporary overshoot and sustained higher temperatures increasingly important.
Greenpeace says governments must act immediately to limit how far temperatures rise above 1.5°C, how long the overshoot lasts and how quickly warming can eventually be brought back down.
The warning follows years of international scientific evidence showing climate damage does not suddenly begin at a single temperature threshold.
Instead, risks increase with each additional increment of warming.
More warming means greater consequences
The report warns temperatures above 1.5°C would intensify a range of interconnected climate threats.
Extreme weather could become more severe.
Ecosystems face increasing losses.
Sea-level rise poses growing risks for Small Island Developing States and low-lying coastal cities.
Human health, food production, freshwater supplies, infrastructure and economies are also expected to face increasing pressure.
The consequences can cascade.
A severe flood is not simply a weather event if it destroys roads, cuts electricity, damages drinking-water infrastructure, closes businesses and forces families from their homes.
A drought is not solely an agricultural problem if it simultaneously affects food prices, employment, hydroelectric generation and community water supplies.
That is why scientists increasingly describe climate change as a whole-of-society risk rather than simply an environmental issue.
Greenpeace turns fire on Coalition Government
Greenpeace says those warnings make the Coalition Government’s climate record increasingly difficult to defend.
The organisation accuses the Government of dismantling climate protections while simultaneously encouraging industries responsible for significant greenhouse gas emissions.
Among the decisions highlighted by Greenpeace are the reversal of restrictions on new offshore oil and gas exploration, changes it says have enabled additional dairy conversions in Canterbury, changes to New Zealand’s climate targets, moves towards an LNG import facility and government support for fossil-fuel-related activity.
These are Greenpeace’s characterisations of the Government’s record, and the Coalition has argued many of its energy and economic policies are necessary to maintain energy security, economic growth and reliable electricity supply.
But Greenpeace says the decisions need to be considered collectively rather than individually.
Its argument is that at a time when international science is demanding faster reductions in emissions, New Zealand is creating opportunities for additional fossil fuel development and emissions-intensive activity.
Fossil fuels back at centre of political battle
The Government’s decision to reopen the door to offshore oil and gas exploration has become one of the clearest dividing lines in New Zealand climate politics.
Supporters argue domestic gas supplies can contribute to energy security and provide backup when renewable electricity generation is insufficient.
The Government has also argued New Zealand needs an energy system capable of supporting businesses and households while the transition towards lower-emissions generation continues.
Greenpeace rejects that approach.
It argues investment in new fossil fuel infrastructure risks locking New Zealand into additional emissions when capital should instead be accelerating renewable energy, storage, electrification and energy efficiency.
The argument is ultimately about what constitutes a transition.
Is gas a temporary bridge towards a renewable future?
Or does building new fossil fuel infrastructure simply extend dependence on the industries the world eventually needs to leave behind?
Agriculture remains New Zealand’s difficult climate equation
The other major challenge is agriculture.
Unlike many developed economies where energy dominates emissions, New Zealand’s emissions profile includes a substantial contribution from agriculture, particularly methane produced by livestock.
That makes farming politically and economically central to the climate debate.
Greenpeace has long targeted intensive dairy farming and what it considers environmentally damaging expansion of the industry.
The Government, meanwhile, has emphasised maintaining agricultural productivity and avoiding policies that could shift food production offshore without necessarily reducing global emissions.
For Māori, the issue is particularly complex.
Iwi, Māori trusts and whānau have substantial interests in agriculture, forestry and food production.
Climate policy that imposes significant new costs can therefore affect Māori landowners and businesses.
But those same communities also face climate-related threats to whenua, freshwater and coastal environments.
The challenge is finding a pathway that protects both oranga whenua and oranga tangata.
Māori communities have more than economics at stake
Climate change carries consequences that cannot always be measured through conventional property values.
A coastal marae threatened by rising seas is not simply another building exposed to natural hazards.
Whenua Māori cannot necessarily be treated as an ordinary property that can be sold and replaced somewhere safer.
Wāhi tapu cannot be relocated without consequence.
Mahinga kai, awa, roto and coastal ecosystems carry whakapapa and cultural significance alongside their environmental and economic value.
That means adaptation and emissions policy need Māori participation from the beginning.
As warming moves beyond 1.5°C, questions around managed retreat, infrastructure investment, insurance and protection of vulnerable settlements are likely to become increasingly urgent.
Pacific neighbours face an existential challenge
The warning also matters enormously across Te Moana-nui-a-Kiwa.
Small island states have spent decades arguing that climate change is not a distant environmental concern but an existential threat.
Rising seas, saltwater intrusion, coastal erosion, extreme weather and pressure on freshwater supplies can threaten entire communities.
For Aotearoa, with deep whakapapa, cultural and political connections across the Pacific, the consequences cannot simply be viewed as somebody else’s problem.
A world that spends longer above 1.5°C increases the challenge confronting many of New Zealand’s closest neighbours.
Every fraction of a degree now matters
One of the most important messages from the latest warning is that exceeding 1.5°C does not mean climate action has failed and there is therefore no point continuing.
Quite the opposite.
There is an enormous difference between 1.5°C, 1.8°C, 2°C and substantially higher levels of warming.
Every additional fraction of a degree avoided can reduce future damage.
Every year that an overshoot can be shortened matters.
And every reduction in greenhouse gas emissions contributes to limiting the eventual scale of warming.
That makes political decisions being taken today significant far beyond a single three-year parliamentary term.
Election 2026 puts climate choices before voters
Climate change is therefore shaping up as another major dividing line ahead of Election 2026.
ACT is questioning the future of the Climate Change Commission and New Zealand’s approach to its Paris commitments.
The Coalition Government has pursued a more development-focused approach to energy and resource policy.
Opposition parties and environmental groups are demanding stronger emissions reductions and greater investment in climate action.
Greenpeace’s intervention is considerably sharper.
It argues the scientific direction of travel is now unmistakable while New Zealand’s policy direction is moving backwards.
The Government will reject that characterisation and argue climate action must be balanced against energy security, affordability, farming and economic growth.
But the UN warning makes one thing increasingly difficult to dispute.
The margin for delay is shrinking.
For Māori, Pacific communities and every part of Aotearoa exposed to floods, drought, coastal erosion and extreme weather, the debate is no longer simply about what the climate might look like at the end of the century.
It is about what governments do now to protect the generations who will inherit it.
If the world is going to exceed 1.5°C, the question is no longer whether every fraction of a degree matters. It is whether governments are prepared to make the decisions necessary to stop every fraction they still can.
