The global economy will be 2% bigger by the end of the century if the world can hold global warming below 1.5 degrees Celsius, according to a new study. Most models predict a period in which the world surpasses that mark for several years or decades, before cooling back down to the 1.5 degree mark (2.7 Fahrenheit) by 2100. This would require removing existing carbon from the atmosphere on an impractically large scale, according to research published in the journal Nature Climate Change . Drawing on modeling from nine teams, lead researcher Keywan Riahi, director of the energy program at Austrian research institute IIASA , found that may be impossible, and a temporary overshoot would likely increase extreme weather such as flooding and wildfires. To avoid permanent damage to ecosystems, the world must avoid surpassing the mark altogether, the report warned. In doing so, there will be less need […]
