In New Zealand, methane discharge from agribusiness also represents a huge burden on our area's runoff. Some of the key effects of environmental change for New Zealand are: • Sea level rise - Sea levels around New Zealand are believed to rise due to the sea expanding as it warms, and also the melting ice sheets . Ocean level rise around New Zealand tends to be similar to global projections. This rise is based on the extent of warming and, crucially, the reaction of the ice sheets in Greenland and Antarctica. • Heavy rainfall and flooding – A warmer environment can hold more moisture (about 7% more for every 1°C increase in temperature). The work displayed suggests that it is possible for New Zealand to require all precipitation extremes to increase by approximately this sum. Additionally, changes in local air diffusion can help increase or decrease precipitation
