چکیده انگلیسی
The areas covered by 1.5â¯Â°C and 2.0â¯Â°C warming thresholds under RCP2.6, RCP4.5, and RCP8.5 were analyzed based on 22 CMIP5 models. More than 90% of the model runs are in agreement that by the end of the 21st century, near-surface air temperature changes over â¼5% (â¼2%), â¼40% (â¼18%), and â¼92% (â¼86%) of the globe will cross the 1.5â¯Â°C (2.0â¯Â°C) threshold under RCP2.6, RCP4.5, and RCP8.5, respectively. Under RCP8.5, nearly the whole of North America, Europeâ¯+â¯Russia, Africa, and Asia-Russia will cross the 1.5â¯Â°C (2.0â¯Â°C) threshold in â¼2050 (â¼2060), while the coverage rates over South America and Oceania are â¼80% (â¼75%) and â¼50% (â¼30%), respectively. The threshold-onset time (TOT) for 2â¯Â°C warming is earliest over Europeâ¯+â¯Russia and North America, followed by Africa, Asia-Russia, South America, and finally Oceania under the RCP4.5 and RCP8.5 scenarios. The TOT for 1.5â¯Â°C is â¼10-30 years ahead of that for 2.0â¯Â°C.
