Those willing to follow the evidence in climate science wherever it leads. Namely, that global warming is real, human-caused and disrupting. That said, there's nothing inherently wrong with all technology and modern life.
Those who think concerns are overplayed and probably motivated by a left-wing agenda. Also those who think the Earth's climate system isn't changing at all (it might even be cooling down). Weather has always been messy and unpredictable anyway.
