Under the United Nations sponsored Paris Agreement on climate change, the international community is aiming to limit warming to 2.0°C, and the researchers warn of the impact that future generations will have to face.
The tropical zone extends from the Andes in South America to northern parts of Argentina and Chile to the Sahara desert.
The Sahara is currently sitting on the edge of the tropical atmosphere, known as the dry subtropical zone of the tropics, and is known for hot and humid summers and mild winters.
The dry subtropical zone moves towards Australia, the country will suffer from severe droughts and less rain will fall in warm regions.
The effects of the growing tropical zone could also create problems for northern parts of Australia.The heatwaves and lack of rainfall won’t just impact humans, but Australia’s entire ecosystem.
Farmers across the country are struggling to feed their animals in the extremely dry conditions, with many fearing the loss of important cattle blood lines, while others have been force to feed sheep onions, kill them, or simply watch them die.
The risk of extreme El Nino events will rise from the current five events each century, to 10 a century by 2050 under a scenario that presumed warming then peaks at 1.5°C.
Distressed farmers have made little income in recent years and are facing heavy financial crisis this year.Farmers are struggling to give water to their animals amid the dry spell, and it looks to be a prolonged and dusty road ahead.
