evidence: Looking at climate-related content from 33 prominent climate contrarian blogs and 20 conservative think-tanks produced between 1998 and 2020, the team began by sorting the climate claims into brackets. They ultimately came up with five major themes of climate misinformation, namely: 1) Global warming is not happening; 2) Human-produced greenhouse gases are not causing global warming; 3) Climate impacts are not bad; 4) Climate solutions won’t work; and 5) Climate science or scientists are unreliable. [...] The analysis revealed that most climate misinformation does not take the form of climate myths—such as the falsehood that recent global heating is the result of a natural cycle—but rather focuses on undermining climate research and proposals to moderate and prepare for climate change. [...] "Ultimately the purpose of all climate misinformation is to delay climate action—whether the argument is ‘global warming isn’t happening’ or ‘climate models are unreliable,’" Cook said. "The conclusion is always ‘therefore we shouldn’t act on climate change.’"
