"Two billion people, including many Australians, will find themselves living in
dangerously hot places this century if global warming reaches 2.7℃, research
released today reveals.

The authors calculated how many people would be left outside the “human climate
niche” by 2100. The niche is defined as places with an average temperature of
about 13℃, or about 27℃ in the tropics. Human population has historically
peaked in these areas.

The world is on track for 2.7℃ of warming by 2100. This would push a third of
people on Earth outside the human climate niche. This includes people in parts
of northwest Australia such as Darwin, Broome and Port Hedland. It also
includes parts of Southeast Asia, India, Africa and South America.

Limiting warming to 1.5℃ would substantially reduce the number of people
exposed, including most of those affected in northwest Australia.

We were not involved in the research, which was conducted by researchers in the
United Kingdom, China, Europe and United States. We are Australian experts in
the health implications of global warming. Below, we discuss the broader
implications of these globally significant findings."
