In this video, Dr Candida Savage, from the University of Otago, talks about how New Zealand’s pristine habitats are like ‘natural laboratories’. This is because they offer good opportunities to ...
Dr Sara Mikaloff-Fletcher, an atmospheric modeller at NIWA, explains how the level of carbon dioxide in the atmosphere has been rising in recent times. She outlines some of the sources for this ...
NIWA scientists collect air samples from an atmospheric research station at Baring Head on Wellington's south coast. What's in the air that we breathe?
Water in the Earth system is influencing all aspects of life on Earth. Pathways, storage, transfers and transformations have an effect on the global climate and human welfare. Within this ...
