with 2021 more than halfway over, it is clear that this year will rank among the hottest in recorded history and possibly break the all-time record set in 2016. if 2021 does top the list, it will do so without the major el ni?o event that boosted global temperatures four years ago—and thus will provide an important marker of the power of the long-term warming trend driven by human activities that emit greenhouse gases.

“until we stop doing that, we’re going to see this over and over again,” says gavin schmidt, director of nasa’s goddard institute for space studies, which keeps the agency’s temperature records. in its first seven months, 2021 has been the second-warmest year on the books, a mere 0.07 degree fahrenheit behind 2016 at the same point, according to new data released today by the national oceanic and atmospheric administration (whose records go back 141 years).

one of this 2021’s notable hotspots has been siberia, which has been covered by an angry, deep-red blotch on global temperature maps. the region has been exceptionally hot since the beginning of the year, contributing to this past january being the planet’s warmest on record. more recently the siberian town of verkhoyansk reported 100.4 degrees f. if this figure is verified by the world meteorological organization, it would be the first time recorded temperatures above the arctic circle have surpassed 100 degrees f.

翻译卡 ?2021年会是史上最热的一年吗？

2021年现已过半，很显着，本年将变成有记载以来最热的一年，并可以打破2016年创下的前史高温纪录。假定2021年真的变成史上最热的一年，那么即便四年前没有发生促进全球气温上升的厄尔尼诺作业，本年也相同会变成史上最热的一年。因而这就给咱们传达了一条重要的信息，标明长时刻以来全球变暖趋势的严峻性，而致使这一长时刻趋势的正是人类活动所排放的温室

气体。

美国宇航局戈达德太空研讨所从事地球表面温度监测的作业，该研讨所所长加文·施密特说：“假定不中止那些致使发生许多温室气体的活动，咱们会不断地看到这种气候异常的表象。”根据美国国家海洋和大气打点局今日发布的新数据（该机构有曩昔141年的有关档案记载），本年前7个月的气温是有观测记载以来的第二高温，仅比2016年同期低0.07华氏度。

2021年气温较高的区域中，值得留心的区域之一是西伯利亚，在全球地表温度图上，该区域被大片的深赤色区域掩盖着。自本年年头以来，该区域（西伯利亚）一向处于异常的高温气候，致使于本年1月的气温变成有观测记载以来全球最高温度。传闻迩来西伯利亚的韦尔科扬斯克（verkhoyansk）的气温抵达了100.4华氏度（38摄氏度）。假定这个数据得到世界气候组织的证明，这将是有记载以来北极圈以上温度初度跨越华氏100度。
