Abstract

Global surface temperature reached a record high in 2023. Using a global climate model, we show that El Niño along with extratropical variability boosted 2023 to be the hottest year on a background warming of 0.2 °C/decade. Our model initialized in July 2024 correctly predicted that 2024 was on track to become yet another hottest year on record.

是什么让 2023 年和 2024 年连续成为最热的年份？

全球地表温度在 2023 年创下历史新高。通过使用全球气候模型，我们发现厄尔尼诺现象和外热带变率使 2023 年成为背景升温 0.2 ℃/十年的最热年份。我们在 2024 年 7 月初始化的模型正确预测，2024 年将成为有记录以来最热的一年。

期刊介绍： npj Climate and Atmospheric Science is an open-access journal encompassing the relevant physical, chemical, and biological aspects of atmospheric and climate science. The journal places particular emphasis on regional studies that unveil new insights into specific localities, including examinations of local atmospheric composition, such as aerosols. The range of topics covered by the journal includes climate dynamics, climate variability, weather and climate prediction, climate change, ocean dynamics, weather extremes, air pollution, atmospheric chemistry (including aerosols), the hydrological cycle, and atmosphere–ocean and atmosphere–land interactions. The journal welcomes studies employing a diverse array of methods, including numerical and statistical modeling, the development and application of in situ observational techniques, remote sensing, and the development or evaluation of new reanalyses.
