If you look only at the religiously unaffiliated, the percentage of warming by human activity folks increase to 58%, or 77% of those who think there’s global warming. Looking at the chart, clearly religion has an influence on temperature perception and attributed cause. The more religiously conservative, the less likely a person is to notice the warming and attribute it to human activity. Religious influence is endangering our life support system in (at least) two ways: Ignoring the problem of climate disruption (if you think that it’s either not happening or we’re not the biggest contributor, you’re not going to do anything about it) and multiplying fruitfully without regard to overpopulation (the more people there are on the planet, the more consumption happens, contributing more CO2 to the atmosphere).
The Pew Forum presents an interesting chart showing what people think about global warming: If it occurs and if so, what causes it. All this is broken out by religious affiliation. Overall, 71% of the US population agree that the average temperatures are rising but only 47% of the population (or two-thirds of people who agree with a warming trend) think that this is mostly due to human activity. So, one-third of those observing the warming trend think it’s caused by natural patterns. Apparently, they know better what’s going on than the experts… But fully 21% don’t even notice that there is warming going on – I guess it’s cooler when your head is firmly in the sand.
