Abstract

It’s hard to say anything about climate breakdown in 2021 that nature isn’t already saying through unprecedented heat waves, bush fires and flooding. The Sixth Assessment Report (AR6) from the Intergovernmental Panel on Climate Change on the physical science of climate change published this year1 confirms this stark “new normal.” Global temperature has already risen by an average of 1 degree and will continue to increase until at least the mid-century under all emissions scenarios considered. Extreme weather events are occurring more frequently and more severely, and the entire globe is impacted by this. Further updates, including on specific impacts for Aotearoa New Zealand, will be published in the next year.
