(3/5) Our #Whakahuraprogramme member Daithi Stone on this research: "The best way to tackle future storms is to reduce our greenhouse gas emissions to halt, or even reverse, the warming of our climate." niwa.co.nz/news/cyclone-gabr…

Cyclone Gabrielle was intensified by human-induced global warming

A new NIWA-led study has found that climate change increased the amount of total rainfall during Cyclone Gabrielle by 10%.

(4/5) In March 2023, our team members were involved in this report on a rapid attribution assessment of the rainfall associated with #CycloneGabrielle. This early report found that the intensity of the rainfall was likely attributable to climate change. doi.org/10.25561/102624

(5/5) This year, our team members provided "the first comprehensive assessment of changes to the characteristics of daily rainfall" over NZ. This important article found that the wettest days of the year may become ≥10% more intense under climate change. doi.org/10.1088/1748-9326/ad…

5/6 In this article, @harrinluke stresses the need for maximum heat standards for early childhood and aged care facilities. He highlights that “the hottest days of the year had already warmed by more than half a degree Celsius for many New Zealand cities.” rnz.co.nz/news/national/4982…

Maximum heat standards needed to protect children and elderly - climate researcher

Children, the elderly and some people with medical conditions are especially vulnerable to becoming dangerously unwell during heats higher than they're used to, experts say.

6/6 The above article also notes that it is the cities with smaller temperature ranges such as Auckland and Hamilton that may face higher risks from extreme heat. “Because their temperatures are more even, their hot spells tend to be longer, with less reprieve overnight.”

Our #Whakahuraprogramme colleague Ilan Noy (@DisasterNz) on RNZ: "every day that goes by without a nationally-driven, properly funded system for moving people out of harm's way - and not putting them there in the first place - is a day gambled." rnz.co.nz/news/in-depth/5162…

Managed retreat: How do we get out of the way of climate change?

"Ad hoc" house buyouts after major disasters cannot continue, the Climate Change Minister says.

Listen to our #WhakahuraProgramme colleagues, Luke, Daithi & Ilan, on RNZ’s Our Changing World discussing climate attribution and impact studies. Luke: “Climate change isn't a future problem… it's already playing out now.” rnz.co.nz/national/programme…

How much of our extreme weather is due to climate change?

This week, Phil Vine dives into the science of climate attribution. How much is climate change affecting extreme weather events? And how can this new science prepare us for the future?
