We’re already feeling the effects of a changing climate in Christchurch, in the form of hotter and drier summers, more intense storms and floods, and higher sea levels.
The hottest year on record for New Zealand was 2022, followed closely by 2023. Future projections show these impacts will become more frequent and severe if we don’t rapidly and significantly reduce greenhouse gas emissions.
Some changes are unavoidable because of our past emissions, so we all need to understand and prepare for the challenges ahead.
Understanding the risks
We must consider a range of scenarios to be more prepared.
Hot weather and drought
We can expect milder winters and more hot weather in summer.
Strong winds
A warmer atmosphere and ocean mean stronger winds.
Wildfires
More hot, dry and windy weather can increase the risk of wildfires.
Heavy rain and flooding
We can expect heavier rainfall over time, increasing the risk of flooding and erosion.
Rising sea level, coastal and ocean changes
Melting land-based ice is increasing the amount of water flowing into our oceans.
