Roads can be seen intersecting drought-affected farming areas located in south-eastern Australia March 21, 2015. A report titled 'Thirsty Country: Climate change and drought in Australia' by the Australian research body the Climate Council, has argued in its latest paper that the probability of drought will increase, and it will become more severe, because of climate change. The crowdfunded body claimed that since the mid-1990s rainfall in southeast Australia had declined between 15 and 20 per cent, and due to a warming climate, rain across southern Australia had "shifted" further south increasing the risk of drought in south-east and south-west Australia.
