Robert Lyman writes for Friends of Science Calgary: "There are four ways in which actual global trends are diverging more and more from the predictions upon which climate activists base their claims of impending catastrophe and allegedly 'inevitable decarbonization' of the world economy. After almost thirty years of measurement, the gentle rise in average global temperatures is near the bottom of the range projected by the Intergovernmental Panel on Climate Change (IPCC). If, as many now expect, the world enters a cooling trend over the next few decades, average temperatures will fall entirely outside that range, and demonstrate conclusively that the IPCC models do not provide a reliable foundation for climate policy."
