Climate change, as defined by the United Nations: “Refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle.” That’s actually a good definition.
But not willing to leave well enough alone, the UN goes further, spoiling a simple and straightforward definition with: “But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil, and gas.”
It is amazing that before humans burned fossil fuels two centuries ago, it was only natural cycles that changed the climate, not backyard barbecues, gas stoves, and SUVs. Yet the UN does not explain how previous ice ages developed due to global cooling, followed by melting of mile-thick ice over the upper Midwest due to global warming, multiple times over the Earth’s history, long before there was any significant human activity.
It seems that a changing climate was a thing long before Al Gore, Greta Thunberg, and the UN thought they figured it all out. Not only does climate change, based on both short- and long-term cycles, but much of it is also unpredictable. According to the Intragovernmental Panel on Climate Change (IPCC), “The climate system is a coupled non-linear chaotic system, and therefore the long-term prediction of future climate states is not possible.”
