On February 14, 2023 we announced our Rebuttal Update Project. This included an ask for feedback about the added 'At a glance' section in the updated basic rebuttal versions. This weekly blog post series highlights this new section of one of the updated basic rebuttal versions and serves as a 'bump' for our ask. This week features 'Is the CO2 effect saturated?'. More will follow in the upcoming weeks. Please follow the Further Reading link at the bottom to read the full rebuttal and to join the discussion in the comment thread there.
