This makes them easy targets for the climate alarmism that pervades America today. Earth’s climate probably is the most complicated

His slide is taken from Jouzel et al. (2007) and Lüthi et al. (2008) and he asserts that “carbon dioxide levels and temperature track identically” (emphasis added) with
