What will future land use and climate change do to sediments entering southern Tauranga Harbour? To find out, Environment Bay of Plenty commissioned NIWA to model the sources and fates of sediments under various scenarios over a 50-year period.
NIWA is committed to providing the science needed to adapt to and mitigate climate change. By making informed choices now, we can reduce risks, maximise opportunities, foster climate resilience and work towards a carbon-neutral economy.
“When it comes to climate change we are in the beautiful position of knowing what our choices are. We can feel a real sense of opportunity about the future - what role our science can play, and how people can contribute”
Dr Sam Dean, Principal Scientist, Climate, Atmosphere and Hazards
The latest climate change facts you need to know:
The climate we predicted and what actually happened.
During Sep-Nov, mean sea level pressures are likely to be above normal near New Zealand. Temperatures are likely to be above average in all districts. Seasonal rainfall is likely to be near normal in most places, but normal or below normal in western regional of both Islands.
The equatorial Pacific is in a moderate La Niña state, which is likely to continue and may strengthen further through the rest of 2010. Mean sea level pressures are likely to be above normal near New Zealand on average during September-November.
August 2010 mean temperatures were above average (between 0.5°C and 1.2°C above average) across all regions of New Zealand, except for eastern Otago, where temperatures were near average (within 0.5°C of average). Small areas of well above average temperatures (more than 1.2°C above average) were observed in Northland, eastern Bay of Plenty, Nelson and Fiordland. The New Zealand national average temperature was 9.6°C (0.9°C above the 1971-2000 August average).
NIWA biosecurity scientist Dr Graeme Inglis has recently been in Vanuatu, where he joined a team whose task ultimately is to upgrade Star Wharf, Port Vila’s cargo wharf.
In 1997, the Australian and New Zealand Environmental Conservation Council (ANZECC) developed a Code of Practice for Antifouling and In-Water Hull Cleaning. NIWA and a Tasmanian partner are about to begin work on the important job of updating this code.
