Gore had made the false claim that “The second big change is that the climate-related extreme weather events have grown far more numerous and far more destructive”, and Lawson corrected him on that, pointing out what the IPCC says about extreme events. He also corrected Gore’s bogus claims about fossil fuel subsidies, saying that fossil fuels are taxed, not subsidised. He also said that “during this past 10 years if anything mean global temperature has slightly declined,” which is not correct according the most commonly used indices (Lawson’s comment probably came from this graph of the global 2m temperature anomaly).'
Many of the world’s leading models are now projecting warming rates that most scientists, including the modelmakers themselves, believe are implausibly fast. In advance of the U.N. report, scientists have scrambled to understand what went wrong and how to turn the models, which in other respects are more powerful and trustworthy than their predecessors, into useful guidance for policymakers. ... Climate models used by next month’s Intergovernmental Panel on Climate Change report project more warming over an 1850–1900 baseline than those in a 2013 report. Scientists are using recent observed warming to rein them in.
