Not all views of the apocalypse are religious, but many religions include their own "end times" stories as a foil to their creation myths. Climate change is an interesting complement to echatological views of the end of the world, as damage and degradation of the environment are popular "signs". Furthermore, the consequences predicted as the most severe or "worst case scenario" for climate change could bring the Earth into irreversible global catastrophe.
Yale's Project on Climate Change Communication published a study about the six types of Americans from the "alarmed" to the "dismissive". Despite a scientific consensus on anthropogenic global warming/climate change, nearly equal percentages of the population are highly concerned (12%) as least concerned (10%). Though most Americans fall in the middle categories from generally concerned to disengaged (62%), all groups except for the dismissive group felt like they needed more information about climate change. The dismissive group, though science would indicate that they are wrong or perhaps the least accurately informed felt that they were the most informed about climate change (91% of dismissives said they were very or fairly well-informed).

Although knowledge and concern for global warming is polarizing around political parties, there is hope that more people overall are concerned or at least a majority is concerned with the changes occurring in current temperatures and future risks around the globe.
