Textbooks Present the Topic as Uncertain (IMAGE) Southern Methodist University Caption A new study from SMU, Dallas, and Stanford University that analyzed four California science textbooks from major publishers found they position climate change as a debate over differing opinions. Contrary to the near majority of climate scientists who cite scientific data and evidence of human-caused climate change, the textbooks present the topic as uncertain, that humans may or may not cause it, and that its unclear if we need immediate mitigating action, the researchers found.
