Climate Model Inflation: According to the “Centre national de la recherche scientifique”, a French government entity billed as the largest governmental research organisation in France and the largest fundamental science agency in Europe, climate models have been underestimating the worst case for an increase in temperatures from a doubling of carbon dioxide (CO2). In a news release it announced:
“The international climate science community is undertaking an extensive programme of numerical simulations of past and future climates. Its conclusions will contribute significantly to part one of the IPCC Sixth Assessment Report, which is expected to be published in 2021. The French scientists involved in the work, in particular at the CNRS, the CEA and Météo-France, were the first to submit their contributions, and they have now revealed the broad outlines of their findings. Specifically, their new models predict that warming by 2100 will be more severe than forecast in earlier versions. They are also making progress in describing climate at the regional level.
