Our stories

A full carbon budget for New Zealand

To combat climate change and assess the impact of government policies, we need to be able to measure greenhouse gas emissions.

Keeping a watch on freshwater contaminants

Emerging Organic Contaminants are a recently-recognised class of chemicals that can affect freshwater quality, and human and aquatic health.

Exploring the health of New Zealand's lakes

Many of New Zealand’s lakes are deteriorating in health, yet our ability to make informed assessments at a national level is constrained by a lack of critical knowledge about our lakes’ current and historic health. Of the country’s 3800 lakes, we currently have scientific knowledge for fewer than five percent.

Better modelling to support groundwater decisions

Groundwater models provide essential information for the management of New Zealand’s freshwater resources. However, existing models too often suffer from being too data hungry, too slow, and too costly. When designed inappropriately models can provide inaccurate information, undermining any management decisions relying on their output.

Predicting the impacts of sea level rise

New Zealand’s ability to adapt to climate change depends on accurate predictions about what will happen — and what we can do to manage the impacts. A five-year programme jointly led by Victoria University of Wellington, GNS Science, and NIWA aims to improve predictions about how sea level rise will affect our coasts over the next several hundred years.

Understanding Antarctica’s role in a wilder and warmer world

GNS Science is working with researchers in New Zealand and overseas to tackle pressing environmental questions about ice sheet melt and the impact of climate change on the Antarctic and Greenland.
