Extreme rainfall increases exponentially with global warming: Study - Times of India
[ad_1]
WASHINGTON: State-of-the-art climate models drastically underestimate how much extreme rainfall increases under global warming , according to a study published Monday that signals a future of more frequent catastrophic floods unless humanity curbs greenhouse emissions. It comes as countries prepare to meet at the COP28 summit in Dubai beginning later this week, amid fears it could soon be impossible to limit long-term warming to the 1.5 degrees Celsius scientists say is necessary to curb the worst effects of human-caused climate change. Researchers from the Potsdam Institute of Climate Impact Research (PIK) looked at the intensity and frequency of daily precipitation extremes over land in 21 "next generation" climate models used by a UN body in its global assessments. They then compared the changes projected by the models with those observed historically, finding that nearly all climate models significantly underestimated the rates at which increases in preci...
