The current climate warming phenomenon manifests itself with the occurrence of, among other characteristics, extremely hot months and seasons.

Examples include the heat waves of April and May 2018 and of June 2019, which swept through large areas of Europe with considerable damage to nature and the economy. The study looks at thermal anomalies of this kind using average monthly air temperature records from 210 weather stations collected over the period 1951–2018. For the purpose of the study an anomaly was defined as a deviation of the average monthly temperature from the long-term average by at least two standard deviations. An anomaly was considered large-area if it occurred simultaneously at 20 or more stations, which corresponded to about one-tenth of the continent. The study found that positive large-area anomalies were increasingly frequent, some being recorded at 80 stations, and that no cool large-area anomalies were recorded after 2010. Large-area thermal anomalies of both types were the most frequent overall in Central Europe.

当前的气候变暖现象以极热的月份和季节等特征表现出来。

例如，2018年4月，2018年5月和2019年6月的热浪席卷了欧洲大片地区，对自然和经济造成了严重破坏。这项研究使用从1951年至2018年期间收集的210个气象站的平均每月气温记录来研究此类热异常。出于研究目的，异常定义为平均每月温度与长期平均值的偏差至少两个标准偏差。如果异常同时发生在20个或更多的站点上，则被认为是大面积异常，大约相当于该大陆的十分之一。该研究发现，积极的大面积异常现象越来越频繁，有80个台站记录到了这些异常现象，2010年之后没有记录到凉爽的大面积异常现象。
