The human cost of global warming
Simulation/modelling: This type of study uses a computer simulation or mathematical model to predict an outcome. The original values put into the model may have come from real-world measurements (eg: past spread of a disease used to model its future spread).
Around 2 billion people will be exposed to dangerous heat conditions if we remain on the path towards 2.7°C of global warming, according to new international research that outlines the human cost of climate inaction. The study shows that the narrow Goldilocks range of the earth's climate, where it is not too hot or too cold to live, called the “climate niche”, is rapidly shrinking. Australia in particular is highlighted as a country that would experience massive increases in land area exposed to extreme heat, if temperatures rise 2.7°C.
