Climate Change will Impact Kapiti
June 4, 2017
We are called the Kapiti Coast for good reason...our towns are largely coastal. Climate change is already having a major impact on the Kapiti Coast with the council committing many $millions to constructing seawalls and increasingly there is talk of managed retreat.
The Ministry for the Environment provides an overview of how the climate in the Wellington and Wairarapa regions is likely to change into the future and what implications this has for the regions.
Projections of climate change depend on future greenhouse gas emissions, which are uncertain. There are four main global emissions scenarios ranging from low to high greenhouse gas concentrations. This page presents regional projections as a range of values from a low emissions to a high emissions future.
The projected changes are calculated for 2031–2050 (referred to as 2040) and 2081–2100 (2090) compared to the climate of 1986–2005 (1995).
By 2090, Wellington is projected to have from 6 to 40 extra days per year where maximum temperatures exceed 25 degrees, with around 5 to 13 fewer frosts per year.
Seasonal projections show that in winter Paraparaumu is likely to experience 5 to 13 per cent more rainfall by 2090 while Masterton is likely to experience up to to 7 per cent less rainfall.
According to the most recent projections, Wellington and Wairarapa are not expected to experience a significant change in the frequency of extreme rainy days as a result of climate change.
The Ministry for the Environment provides guidance on coastal hazards and climate change, including recommendations for sea level rise, see Preparing for coastal change: A guide for local government in New Zealand.
