Greta Thunberg turned 18 a few months ago but occasionally she forgets that. “I actually can vote now,” she grins. But the words “we children” still sometimes slip into her sentences, out of habit. She is sanguine about the change, but it is a bigger shift than she lets on: that phrase has been a core part of her message.
Michael E Mann rose to prominence in 1999 as the co-author of the “hockey-stick graph”, which showed the sharp rise in global temperatures since the industrial age. This was the clearest evidence anyone had provided of the link between human emissions and global warming. This made him a target. He and other scientists have been subject to “climategate” email hacking, personal abuse and online trolling. In his book, The New Climate War, he argues the tide may finally be turning in a hopeful ...
What can families and schools do to help children and young people overcome fear and anxiety about climate change? New work from the New Zealand Council for Educational Research looks at how to give young people the knowledge, values, skills and opportunities to help ensure a more sustainable future. Kathryn speaks with Rachel Bolstad, senior researcher on the project.
THE RISK IS CLEAR: Antarctica’s collapse has the potential to inundate coastal cities across the globe. If that ice sheet were to disintegrate, it could raise the level of the sea by more than 160 feet — a potential apocalypse, depending on exactly how fast it happened. Recent research suggests that if society burns all the fossil fuels known to exist, the collapse of the ice sheet will become inevitable.
The rich are primarily to blame for the global climate crisis, a study by the University of Leeds of 86 countries claims. The wealthiest tenth of people consume about 20 times more energy overall than the bottom ten, wherever they live. The gulf is greatest in transport, where the top tenth gobble 187 times more fuel than the poorest tenth, the research says. That’s because people on the lowest incomes can rarely afford to drive.
Researchers have found a new low-carbon method to produce the common mineral, magnesium hydroxide or Mg(OH)2. Associate Professor Scott explains magnesium hydroxide has been widely recognised as one of the most promising materials for ‘carbon mineralization’ (where carbon dioxide or CO₂ is prevented from entering the atmosphere), but until now there hasn’t been an energy-efficient way of producing it. “Most processes to get magnesium hydroxide typically involve CO₂ emissions.
Some of the world's biggest forests might start losing their carbon-sucking powers in just a few decades, says a study by NZ and US scientists. We rely on plants to suck in a quarter or more of our fossil fuel emissions. But, unless we slow global heating, up to half the world’s forests and grasslands could pass their peak carbon dioxide uptake within the next 2 to 3 decades, according to a study in the journal Science Advances by researchers at University of Waikato and Northern Arizona Uni...
Many of us acknowledge wanting to do something about climate change, but there are various reasons why we feel stunted in our ability to help. Professor Niki Harré examines the psychology of sustainability, how we can start making changes and keep ourselves motivated. IT WAS IN 2006, after attending a series of seminars and workshops, that psychologist, Professor Niki Harré, became increasingly aware of climate change as an issue that “is about all of us right here and right now”.
In February 2019, the pop star traveled to Antarctica to learn about the climate crisis firsthand. I’ve been obsessed with Antarctica since I was a kid. Growing up in New Zealand, the race to the South Pole is mythologized like the U.S.-Soviet race to the moon — two explorers, one British, one Norwegian, locked in a breathless, romantic fight for national honor. I always rooted for Robert Falcon Scott, the British officer, poring over his grim diaries. I inhaled the frostbite, the deaths...
This weekend, 15 Wellington properties were inundated when intense rainfall hit when the tide was high... As Olivia Wannan explains, this type of event will get increasingly common as global temperatures rise. In our warmer world, we’ll see everything from stronger winds and more intense storms to longer dry spells. Although these effects may seem distinct, the real trouble may hit communities when they combine forces. Together, the rising seas and intensifying rainfall are likely to cause...
