(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. https://t.co/HNXCAxeB8U

(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." https://t.co/n7QCKLRgo1

(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. https://t.co/MU5oyDosR2

(2/5) A new article, partially funded by Whakahura, has found that during #CycloneGabrielle, climate change increased the amount of total rainfall by 10% and the peak hourly rainfall by 20%. https://t.co/twqNPgpdC6

(1/5) #Whakahuraprogramme members have been producing important research on how climate change is amplifying extreme rainfall. Here are a few key articles and insights.🧵

6/6 He notes that arguments against this te ao Māori approach are “nothing compared to the difficulties we will [soon] face… if risk and vulnerability to extreme weather and climate change hazards are not reduced and community resilience built up.” https://t.co/HLUUkl59Le

1/6 Shaun Awatere, a researcher in the #Whakahuraprogramme, has been in the media discussing the role of indigenous perspectives in disaster risk reduction. He emphasizes how these approaches offer community-based solutions linked to the natural environment.

5/6 Shaun: “The holistic and relational aspects of a te ao Māori approach to disaster risk reduction make it… more complex to operationalise. Yet, there are numerous projects… where te ao Māori approaches have been operationalised with great success." https://t.co/vC7Txm38dM

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.”

1/6 Our #Whakahuraprogramme members have been in the media discussing how heat is changing due to climate change, and the risks posed by extreme heat.

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.”

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." https://t.co/mEGXOZHgmZ

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.” https://t.co/TpySmEfLvs

RBNZ’s Climate Stress Test results: To reduce their exposure to climate-related risks, banks could limit new lending in flood prone areas (physical risk) & to sectors sensitive to higher emissions pricing (transition risk). @BelindaStorey's #CreditRetreat https://t.co/BvEAa51xVp
