联合国证实的北极记录的最高温度

联合国一部分的专业机构世界气象组织（WMO）现在正式将温度视为该地区的纪录，它说这听起来为气候变化的“警钟”。

温度是在2020年6月20日在北极西伯利亚的“出色且延长的夏季热浪中，在Verkhoyansk镇的一个气象观测站记录。

WMO秘书长Petteri Taalas教授说：“这一新的北极记录是向WMO天气和气候极端档案报道的一系列观察，听起来我们气候变化。在2020年，南极大陆也有新的温度记录（18.3°C）。”

Taalas added: “WMO investigators are currently seeking to verify temperature readings of 54.4°C recorded in both 2020 and 2021 in the world’s hottest place, Death Valley in California, and to validate a new reported European temperature record of 48.8°C in the Italian island of Sicily this summer.

“天气和气候极端的WMO档案从未进行过如此众多的同时调查。”

WMO警告说，北极是“世界上最快的变暖区域”之一，称现在它的暖气是全球平均水平的两倍以上。

这organisation said average temperatures over Arctic Siberia reached as high as 10°C above normal for ‘much of summer last year’, in turn fuelling ‘devastating fires, driving massive sea ice loss and playing a major role in 2020 being one of the three warmest years on record’.

这ongoing climate change has prompted a WMO panel of experts to add a new climate category - ‘highest recorded temperature at or north of 66.5⁰, the Arctic Circle’ - to its international Archive of Weather and Climate Extremes, which includes the world’s highest and lowest temperatures, rainfall, heaviest hailstone, longest dry period, maximum gust of wind, longest lightning flash and weather-related mortalities.

WMO气候和天气的报告员Randall Cerveny教授说：“从根本上讲，这项调查突出了世界上重要的世界上重要地区的温度日益增加。

“通过对极端温度的持续监测和评估，我们可以对世界关键区域（极地北极）的变化保持知识。

“它强调了维持长期观察的必要性，这为我们提供了气候系统状态的基准。”
