This is how we're responding in Christchurch.
Climate change projections show that Christchurch’s average temperatures will rise 0.5 to 1.5ºC by 2040, and the number of days where temperatures exceed 25ºC will also increase. By 2040, there could be 10 more days a year over 25ºC, and in winter, fewer frosts are expected.
Summer and autumn will be drier, while winter will be wetter, with up to 10% more rainfall. Longer dry periods will bring more intense, frequent drought.
The city's low-lying areas, particularly the lower Ōtākaro-Avon River and margins of the Avon-Heathcote Ihutai Estuary, will be vulnerable to sea level rise and increased flooding as groundwater comes closer to the surface, and coastal erosion may become more frequent and intense. Banks Peninsula will experience more drought, which will impact surface water supply. The Port Hills and Banks Peninsula will experience longer, more frequent conditions that increase wildfire risk.
Here are some of the ways Christchurch is responding to climate change.
