As the world warms the poorest locations tend to experience more perceptible warming. Beyond net-zero emissions this inequality persists, but getting to net-zero sooner limits how much worse it gets. iopscience.iop.org/article/10.1...

This report shows what targets Australia should adopt to align with the 1.5°C Paris Agreement goal that Australia has signed up to. For Australia to be playing its part it would need to strengthen the 2030 target and achieve at least 81% emissions reduction (relative to 2005 levels) by 2035.

Out today: our comprehensive review of Australian droughts. It covers the nature and drivers of drought development, intensification & termination - and how those are changing with climate change. www.nature.com/articles/s43...
Scientific diagram summarising the causes of drought development, intensification, and termination in Australia. The graphic shows that drought development and intensification is associated with El Nino and positive IPO conditions in the Pacific Ocean, positive IOD conditions in the Indian Ocean, reduced onshore moisture transport, high pressure systems over south-eastern and south-western Australia, dry MJO phases, and wind-evaporation feedbacks - with all affected by anthropogenic forcing. Drought termination is associated with La Nina and negative IPO conditions in the Pacific Ocean, negative IOD conditions in the Indian Ocean, enhanced onshore moisture transport, cut-off low weather systems in south-eastern Australia, monsoon lows in north-western Australia, and wet MJO phases - with all affected by anthropogenic forcing.
