Climate Change

Climate scientists and glaciologists are taking to the skies this week to find out how New Zealand’s glaciers are faring following this summer’s record-breaking warmth.
Ancient swamp kauri is being used by NIWA scientists to reveal the secrets of past climates.
Despite a sub-tropical storm and two ex-tropical cyclones, this summer is about to become the hottest in history.

John McGregor from NIWA checks on the instruments that measure atmospheric gases throughout our voyage.

A two-week expedition to tag blue whales in New Zealand waters for the first time, almost came up empty due to warmer sea temperatures causing the animals to change their behaviour.

Hazard risk is compounding in low-lying coastal areas of New Zealand, because hazard events are occurring more often (on the back of a rising sea), while at the same time coastal development and property/infrastructure values are increasing.

Rapid warming of the ocean near Tasmania may provide a good indication of how the water around New Zealand will change as the planet warms, say NIWA scientists.

New Zealand winters are a month shorter than they were 80 years ago, NIWA scientists say.

“This is a consequence of rising temperatures around the globe, and such trends in colder temperatures and frosts will influence the life cycle of plants and animals” - Dr Brett Mullan.

A dramatic change in sea ice this year is likely to hamper a NIWA-led research project aiming to better understand how ice shelves will melt as the ocean warms.
A decade of scientific research into how ocean acidification is affecting New Zealand waters has led to far greater understanding of the vulnerability of our marine ecosystems, according to a newly published review.
The Deep South National Science Challenge is one of New Zealand’s most audacious collaborative projects in recent times.
Pioneering NIWA scientists are returning to the cold continent in October, this time to focus on the seabed.
Tropical cyclones forming in the south-west Pacific are becoming less frequent but those that do form are likely to be more severe.
The construction of improved climate information and services in Vanuatu has posed unique logistical challenges.
The most commonly grown variety of kiwifruit around Te Puke will not be commercially viable in the area by the end of the century, say scientists.
Sitting at the surface of Taylor Glacier in Antarctica, are layers of ice more than 10,000 years old. And trapped inside those layers are bubbles of ancient air – like tiny time capsules - able to tell scientists a story about what the world used to be like and how humans have changed it.
Wellington city will have warmer autumns, almost a month of days over 25°C and up to 10 per cent more winter rain by 2090, according to a new NIWA climate report.
Regional-scale climate projections assist New Zealand’s local government authorities to adequately assess the local risks presented by climate change now and prepare their communities for the future impacts of climate change.
New research estimates that if climate change goes unchecked 60,000 more people will die globally from air pollution in 2030 – just 13 years away.
The latest atmospheric river over New Zealand delivered one town’s wettest day on record, and broke several other long-held rainfall statistics, according to NIWA data.

The process of developing a National Adaptation Plan (NAP) for climate change was established under the 2010 Cancun Adaptation Framework. NAPs are forward-looking, holistic plans which are generally country-driven, given the local nature of adapting to climate change.

New Zealand climate change scenarios and impacts based on the 2007 IPCC 4th Assessment report.

The effects of climate change on fish are being studied in a world-first trial at NIWA’s Bream Bay marine science centre.
