Sea-level rise is coming, and planning for it is already underway, but coastal development across New Zealand relies on sea-level rise projections that are increasingly out-of-step with the latest science.
Councils around New Zealand vary greatly in terms of their official estimates of future sea level rise, which are used in property development and coastal planning, and this week the Ministry for the Environment confirmed to the SMC that it had abandoned plans for National Environmental Standard to get all the councils’ sea level projections in line.
So what are the most up-to-date estimates that New Zealand should be working with?
The Science Media Centre hosted an online briefing for journalists on the science of sea-level rise, featuring keynote speakers from the New Zealand Climate Change Centre’s conference which will take place this Thursday, which will bring local and central government officials together to hear the latest science and discuss planning for sea-level rise. You can listen to the briefing below.
Registered journalists can access speakers slides in the SMC Resource Library.
