The idea that climate change can be attributed to just one or two politically chosen factors, such as the so-called ‘greenhouse gases’, like carbon dioxide and methane, is simply very bad science. Climate change is controlled by millions of interlinked factors, ranging from the swish of a butterfly’s wing, through 11- and 22-year solar magnetic cycles, volcanism, ocean-atmospheric linkages, sunspot activity, shorter duration wobbles of the Earth, to 96,000-year orbital changes and even intermittent meteor impacts. The intrinsic complexity of all these myriad links still totally defeats our climate modellers, many of whom cannot even account for the variation of water vapour, the most important greenhouse gas of all, and this means that climate change remains largely unpredictable. Moreover, this inherent unpredictability should warn us that, when, God-like, we try to adjust one or two of the factors involved, such as greenhouse gas emissions, our very best intentions may bring about results we neither expect nor want. We have no knowledge of how the tiny changes we initiate may interact with all the other ever-changing cycles.
