Climate Change

Climate change is a phrase we use to describe changing climate patterns that: can be attributed to human activity that alters the earth’s atmosphere; are beyond natural climate variations observed over comparable time periods.

The effects of global warming and climate change are already measurable. New Zealand’s climate is changing, largely because of the build-up in the earth’s atmosphere of greenhouse gases particularly carbon dioxide, methane and nitrous oxide.
