Climate change could decrease global GDP by 40%

A new study indicates global warming's economic impact may be worse than previously thought. Researchers in Australia suggest past economic models underestimated the effects of climate change on food security and wealth. The study projects that if global warming reaches 4 degrees Celsius, the average person could be 40% poorer by 2100. Even if warming is limited to 2 degrees Celsius, global per capita Gross Domestic Product (GDP) could decrease by 16%. The researchers incorporated extreme weather events and their impact on global food supplies into their analysis. This contrasts with past models that didn't fully account for widespread disruptions to global supply chains caused by extreme weather.
