Earth's climate is changing. Over the last 50 to 100 years, this process of change has sped up. It is largely recognised that the increasing amount of human-caused emissions of greenhouse gases in our atmosphere is the reason the globe is warming at an unprecedented rate. The effects of this are already visible, and the changes ahead of us will be much larger and will happen more quickly than any recent natural climate variations. (

In New Zealand likely climate change impacts include:
  • higher temperatures, more in the North Island than the South, (but still likely to be less than the global average)
  • rising sea levels
  • more frequent extreme weather events such as droughts (especially in the east of New Zealand) and floods
  • a change in rainfall patterns - higher rainfall in the west and less in the east.

These changes will result in both positive and negative effects. For example:
  • agricultural productivity is expected to increase in some areas but there is the risk of drought and spreading pests and diseases. It is likely that there would be costs associated with changing land-use activities to suit a new climate
  • people are likely to enjoy the benefits of warmer winters with fewer frosts, but hotter summers will bring increased risks of heat stress and subtropical diseases
  • forests and vegetation may grow faster, but native ecosystems could be invaded by exotic species
  • drier conditions in some areas are likely to be coupled with the risk of more frequent extreme events such as floods, droughts and storms
  • rising sea levels will increase the risk of erosion and saltwater intrusion, increasing the need for coastal protection
  • snowlines and glaciers are expected to retreat and change water flows in major South Island rivers. (
