因果效应的识别是气候变化研究中的一个基本问题。在此，利用英格兰中部温度（CET）数据集（最长的仪器温度记录）以及慢特征分析和小波分析相结合的方法，提出了气候变化因果关系的一个新视角。对气候变化的驱动因素进行了研究，结果显示出两个独立的自由度——一个3.36年的周期和一个22.6年的周期，它们似乎分别与厄尔尼诺 - 南方涛动周期和黑尔黑子周期有关。此外，这些驱动因素的振幅受到具有千年时间尺度的信号的调制。
The identification of causal effects is a fundamental problem in climate change research. Here, a new perspective on climate change causality is presented using the central England temperature (CET) dataset, the longest instrumental temperature record, and a combination of slow feature analysis and wavelet analysis. The driving forces of climate change were investigated and the results showed two independent degrees of freedom —a 3.36-year cycle and a 22.6-year cycle, which seem to be connected to the El Niño–Southern Oscillation cycle and the Hale sunspot cycle, respectively. Moreover, these driving forces were modulated in amplitude by signals with millennial timescales.
