Detection and attribution of observed climate trends and events is called 'climate attribution'. This has been assessed by IPCC WGI  and summarised in Chapter 16. Trends that have been formally attributed in part to anthropogenic climate change include regional warming trends and sea level rise , decreasing rainfall and increasing fire risk in southern Australia. Events include extreme rainfall in New Zealand during 2007-2017, the 2007/2008 and 2012/2013 droughts in New Zealand, high temperatures in Australia during 2013-2020, the 2016 northern Australian marine heatwave, the 2016/2017 and 2017/18 Tasman Sea marine heatwaves and 2019/2020 fires in Australia.
