Limiting global warming to 1.5C would have ‘significant economic benefits’
Holding global temperature rise to 1.5C would lead to significant economic benefits by the end of the century, a new paper suggests. It finds that per capita GDP would be 5% higher by 2100 if temperatures are stabilised at 1.5C above pre-industrial temperatures rather than 2C. Amir Jina, an assistant professor in public policy at the University of Chicago and Impact Lab researcher, who was not involved in the study, says its findings generally agree with his recent research. ... “[We] could say that the lack of a significant difference between 1.5C and 2C shows why we should be interested in this type of paper – it tries to quantify these targets that have been set as convenient goals rather than rigorous scientific benchmarks," Jina said. "In that context, saying that 2C warming is worse than 1.5C warming, in the median, is not too surprising. Quantifying both of these is useful for policy, however."
