Andy Reisinger and Dan Zwartz discuss the interplay between climate change observations and models, looking in particular at the issue of sea-level rise.
They present some of the field science that tells us how and why sea level has changed in the past, and how it is changing now. They also discuss how much uncertainty there is in projections of future sea-level rise and what this means for coastal planning in New Zealand.

Dan made his first trip to Antarctica more than 20 years ago, while studying geology at Victoria University's Antarctic Research Centre. He has spent years investigating how the Antarctic ice sheets affect global sea level, and has joined or led a number of expeditions to many locations in East Antarctica with the Australian, Dutch, and Japanese national research programmes.
In February 2012, Dan participated in Gareth Morgan's Our Far South voyage to raise New Zealanders' awareness of issues in the Southern Ocean and Antarctica.
Dr Andy Reisinger is Deputy Director (International) of the New Zealand Agricultural Greenhouse Gas Research Centre. His research interests include climate change impacts and adaptation with a focus on local government, exploring uncertainty and its implications for decision-making, and the role of agricultural greenhouse gas emissions in climate change policy.
