A small group of Kiwi scientists is attempting to construct the ultimate crystal ball—a mathematical model of the Earth’s natural systems so intricate that it can predict the behaviour of our atmosphere, land and seas, human industry and biological production, far into the future.
With predicted increases in sea level of a metre or more by the end of this century, present-day problems of coastal erosion, flooding and salt-water intrusion into groundwater are going to get much worse.
From native frogs to alpine plants, signs of change are all around us, a frightening barometer with which to gauge our changing climate and a reminder that if we can conserve these species most at risk, there is hope for all.
Our decades of indulgence have cost the planet, and Nature just dropped off the bill. Who’s going to pick it up?
Global warming could transform the country and the planet, but it will also have a much more immediate impact on the world we live in, with respect to both the climate we experience and the way we lead our lives.
How are we to deal with an issue of the magnitude of climate change? How do we approach what UN Secretary-General Ban Ki-moon has called “the defining challenge of our age.”
When did New Zealand's foreign policy get so feeble?
University of Arizona emeritus professor Guy McPherson says we're heading for the planet's sixth mass extinction in just 10 years.
The record of the Earth’s past climate has been frozen in ice bound up in ice sheets and glaciers on land, and floating on the seas in great ice shelves. Cores extracted from this ice tell an alarming story, and dramatically alter climate projections.
A new report reveals how 12 companies profited from pollution using fake carbon credits from Russia.
As droughts and floods hit in equal measure, farmers bust find new ways and means of agriculture. But many are struggling to change as fast as the climate.
The East Antarctic ice shelf is more vulnerable than previously thought, with warmer water melting it, scientists say.
A Waikato law student is suing the government over its climate change policy, claiming its greenhouse gas emissions targets were arrived at illegally, and that the low emissions reduction pledge it will make in the upcoming UN climate conference in Paris in December is “unreasonable and irrational”.
Antarctica’s fragile ecosystem is a barometer for the warming and acidification of Earth’s oceans. Over the last decade, NIWA scientists have been diving under the ice as part of Project IceCUBE to gauge just how the ecosystem might cope with these threats.
The weather forecasts for central Marlborough had a monotonous sameness last summer, as El Nino kept clouds away and turned pastures to brick.
Anyone who is even vaguely alert will be aware that there's something up with this planet of ours. What's Up?
As temperatures around the world slowly rise, glaciers steadily retreat. New Zealand has over 3000 glaciers in its mountains, among them two of the fastest moving, most accessible and spectacular in the world—the Fox and Franz Josef.
