Since the industrial revolution began in the mid-1700s, atmospheric carbon dioxide concentrations have gone up by 46%.
For the past two and a half million years, Earth has experienced regular ice ages, but with carbon dioxide levels now over 400 parts per million, the next ice age is postponed for a very long time.
The climate crisis is itself an appalling lapse in duty of care by decision-makers, but we shouldn’t overlook this duty in our response.
Climate change is a super-wicked problem. With a growing sense of urgency to act on climate change, it is vital we strike a balance between encouraging action and limiting pushback.
New Zealand is one of few places in the world where teaching the country’s own history has not been compulsory.
Teaching history is as much about facts and people as it is about contested narratives and disputed interpretations, which is why it's time to make New Zealand history a compulsory subject at school.
Auckland Council’s upgrade plans highlight the importance of local Māori communities as part of the process.
As part of an upgrade of Auckland's city centre, the council promises to include local Māori communities and their histories. But without addressing inequalities, it is no more than a token gesture.

Despite repeated calls for an overhaul of New Zealand's marketing regulations to protect children from exposure to ads for unhealthy products, successive governments have failed to act.
Returning nutrients, including animal feces, to the land is important to maintain the soil’s capacity to sequester carbon.
Regenerative agriculture has the potential to build production and reducing pollution, but it needs a clearer definition.
The new measures that give police discretion not to prosecute are in keeping with Prime Minister Jacinda Ardern’s decision not to join US President Donald Trump’s “war on drugs”.
A change to drug laws in New Zealand has been hailed as a leap towards treating drug addiction as a heath issue. But it has also been criticised for essentially decriminalising class A drugs.
After years of delay, the New Zealand government is pushing ahead on a national plan to clean up the nation’s lakes, rivers and wetlands.
A proposed plan to clean up New Zealand's waterways draws clear limits on the expansion of dairy farming and irrigation, as well as on the use of nitrogen fertiliser in some key areas.
Agriculture is an important sector for both New Zealand and the European Union.
New Zealand is in the process of negotiating a free-trade agreement with the EU. Agriculture is likely to become an issue because it is heavily subsidised in Europe but not in New Zealand.
While growing grass takes up carbon dioxide, it emits it again back into the atmosphere when it is mowed or eaten.
All plants take up carbon dioxide when they grow, but when they are harvested or cut down, they release the greenhouse gas back into the atmosphere.
The land occupation at Ihumātao brings together Māori and heritage activists seeking to stop a housing development on a site that marks the earliest human occupation of New Zealand.
The land occupation at Ihumātao, near Auckland's airport, is reviving forms of protest common in the 1970s, now enhanced by new media and led by a new generation of Māorikeen to see grievances addressed.
People with high cultural intelligence are more likely to have broader knowledge of foreign politics and economic systems.
People with high cultural intelligence are non-judgemental, tolerant of ambiguity and inclusive – and these qualities mean they are more likely to be successful in global business positions.
The number of Māori and Pasifika students is growing, but they do not see themselves represented among the people who teach them.
New research shows that Māori and Pasifika scholars are significantly under-represented in New Zealand's universities, making up only 5% and 1.7% of the academic workforce, respectively.
Putting a price on greenhouse gas emissions forces us to face at least some of the environmental cost of what we produce and consume.
Traditional market transactions ignore the costs of greenhouse gas emissions. An emissions trading scheme is a tool to put a price on emissions and to influence us to choose lower-emission options.

More than 50 advertisers have so far withdrawn from Alan Jones’ 2GB radio show, buoyed by social media campaigns naming and shaming those who remain.
The advertising boycott of Alan Jones' radio show highlights which companies advertised on it, but ironically, pulling out now could enhance their brand more than if they had never supported the show.
Rather than encouraging people to become better citizens, rewards and fines can actually reduce peoples’ natural tendencies to do the right thing by others.
The idea that a small payment could motivate more people to vote resurfaces regularly, but this ignores evidence that monetary incentives to induce pro-social behaviour can be counterproductive.
If it were possible to download the neural networks of a human brain, could we preserve a computer simulation of that person?
The quest for immortality is as old as humanity itself, but the prospect of being able to copy the neural networks of a person's brain shifts the pursuit of perpetual life into the digital world.
Many workers are exposed to work environments that leave them feeling depressed and burnt out.
Data from a workplace barometer study show more than a quarter of employees felt depressed often, a half said depression affected their lives and for 8% life was "very or extremely difficult".
Research shows the cost of damage through climate change will be much greater than the costs of reducing emissions.
New Zealand is small and generates a tiny fraction of global greenhouse gas emissions, but investment in cutting emissions is important and could influence other, larger countries.
