The El Niño of 1997-8
Another paper attempting to shed some light on the mysteries of long-term cyclical climate patterns is brought to our attention by the GWPF. The abstract looks fair but there are a few nods in the direction of ‘greenhouse gases’ later in the paper, in particular related to what they identify as millennial signals.
Abstract
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…
