The New Zealand government has ordered officials at the Ministry of Environment to stop work on the development of a national environmental standard (NES) on sea level rise, enquiries by the Science Media Centre have revealed. Lack of an NES for future sea level increases will force each local authority to make up its own mind about how much to allow for ocean encroachment. A ministry spokesman told the SMC:
At this stage there are no plans to progress the proposed NES. The Minister for the Environment has made it clear that current guidance provides local government with both the information and the flexibility to plan locally for rises in sea levels.
An NES on sea level rise would have simplified sea level planning for local authorities, who currently may choose to rely on “guidance” provided by the ministry, based on work by NIWA. This currently suggests that authorities should allow for 0.5 m rise by the 2090s, and that they should consider the impacts of a 0.8 m rise in that time frame.
There are two major problems here: the current guidance numbers, first published in 2009, are increasingly out of line with the latest research, and the lack of a national standard means that climate sceptics can waste time and ratepayer money by forcing planning authorities to adjudicate on their minority views.
