(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.

(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.

(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."

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.”

“We know which marae are above the flood zone. We know how to support traumatised people. Why wasn’t that built into the system?” - cyclone report

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."

An independent review highlights the need to recognise marae as “vital providers of community intelligence and services,” and recommends formalising iwi/Māori involvement in […]

4/6 Shaun describes te ao Māori approaches to disaster risk reduction as more collective, empowering "local communities to draw upon their locally based solutions, using their own innovations, to get more improved outcomes for disaster risk reduction.” https://t.co/f4P3hyeNqS

3/6 “These communities and whānau are often the ones that are the most isolated & the most marginalised. Indigenous researchers can play [an]… important part in… amplifying the voices of those who are impacted so that their views & experiences can be factored into… solutions.”

2/6 Shaun highlights the importance of indigenous perspectives in developing long-term, community-based solutions connected to the natural environment. He points to last year’s extreme weather events, which were devastating for communities. https://t.co/VTLuEjCgWl

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.

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.”

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.” https://t.co/TXOBojPit4

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.

4/6 One insight from above is that “People in equatorial areas born in the 60s and 70s… have experienced more perceptible warming than anyone else on Earth.” Also, that many young people in lower-income countries may later experience a climate unrecognisable to their youth.

2/6 @NathanaelMelia: when it comes to climate change, “there is no magic number - every fraction of a degree hotter has an impact.” Because climate extremes do not go up in a tidy line, a small increase in average temperatures can have major effects. https://t.co/0NIHtlhkTX

2023 was "extraordinary" and a sign of what is to come, climate scientists say.

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."

"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.”

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?
