Drought forecasting dashboard
NIWA and MPI are working together to develop a new drought forecasting tool. It uses innovative climate modelling, the latest in machine learning and other data-driven techniques to predict rainfall 35 days ahead. It will help farmers and growers better prepare for periods of dryness and drought.

What is ocean acidification?
Education ResourceOcean acidification is the name given to the lowering of pH of the oceans as a result of increasing carbon dioxide (CO2) in the atmosphere. -

What is the greenhouse effect?
Education ResourceThe greenhouse effect is a warming of the earth's surface and lower atmosphere caused by substances which let the sun's energy through to the ground but impede the passage of energy from the earth back into space. -
Floods
Education ResourceRiver floods occur when water spills from a river channel onto land that is normally dry, and are one of New Zealand's costliest natural hazards. -
Otago
The climate of Otago is perhaps the most diverse of any region in New Zealand.
