The National Oceanic and Atmospheric Administration says global temperatures during August were the warmest on record--nearly a degree Celsius higher than the 20th century average of 15.6 degrees. ________________________ Scientists say the high temperatures are the result of a combination of climate change related to greenhouse gas emissions and an El Ni?o weather system over the Pacific Ocean that adds heat to the atmosphere. 国家海洋和大气管理局表示,八月份全球平均气温达到了历史极值-比20世纪的平均值15.6°C将近提高了1°C. _________________ 科学家表示,由于温室气体排放和太平洋上空的厄尔尼诺现象,大气的温度升高从而引起气候变化,因而造成了全球温度升高.
