据英国《每日邮报》报道，今年北半球经历了现代史上最温暖的夏天国家海洋和大气管理局。
这一记录超过了1990年创下的记录2019和2016年，之前并列最热。
事实上，过去的三个月对整个地球来说都是闷热的，这是自1880年开始录音以来第三个最热的夏天。美国国家海洋和大气管理局(NOAA)科学家发现，8月份全球陆地和海洋表面平均温度比20世纪的平均温度60.1华氏度高出1.69华氏度。

2020年8月也是北半球历史上最热的8月，也是世界上第二热的8月。
地球上最热的10个8月都发生在1998年以后。自2015年以来，最热的八月有五个。

据美国国家海洋和大气管理局称，北极海冰也在持续减少。

Northern Hemisphere had warmest summer on record, NOAA says
The Northern Hemisphere experienced its warmest summer in modern history this year, according to theNational Oceanic and Atmospheric Administration.
The record surpassed those set in2019and 2016, which previously tied for the hottest.
In fact, the last three months were sweltering for the entire globe, which saw its third-hottest summer since recordings began in 1880. The average global land and ocean surface temperature in August was 1.69 degrees Fahrenheit above the 20th-century average of 60.1 degrees, NOAA scientists found.
August 2020 was also the warmest August in history for the Northern Hemisphere and second-warmest in the world.
The 10 warmest Augusts on Earth have all occurred since 1998. Five of the warmest Augusts have occurred since 2015.
Arctic sea ice has also continued to decline, according to NOAA.
The average Arctic sea ice extent (coverage) in August was the third-smallest on record, 29.4% below the 1981–2010 average, according to analysis by theNational Snow and Ice Data Center.
A 44-square-mile area of the Nioghalvfjerdsfjorden ice shelf detached from northeast Greenland, a series of satellite images taken byEU Copernicus and the Geological Survey of Denmark and Greenlandbetween 2013 and 2020 shows, according to the organization.
"We should be very concerned about what appears to be progressive disintegration at the Arctic's largest remaining ice shelf, because upstream it is the only major Greenland ice sheet ice stream, draining 16% of the inland ice reservoir," GEUS Professor Jason Box said in a statement.
