Heat Could Make Earth Uninhabitable By Year 2300

(ChattahBox) – A collaborative study between the University of New South Wales (Australia) and Purdue University (USA) has shown that climate change could make the world unlivable by humans by the year 2300.
According to Professor Steven Sherwood, the risk of continued fossil fuel burning could lead to a significant heat increase over the next three centuries, with the bulk of the change happening next century.
“It would begin to occur with global-mean warming of about seven degrees Celsius (13 Fahrenheit), calling the habitability of some regions into question. With 11-12 degrees Celsius warming, such regions would spread to encompass the majority of the human population as currently distributed,” the report said.
According to Sherwood, there is a shocking 50/50 chance of this.
“If this happens, our current worries about sea level rise, occasional heatwaves and bushfires, biodiversity loss and agricultural difficulties will pale into insignificance beside a major threat — as much as half the currently inhabited globe may simply become too hot for people to live there,” he said.
