I hate how real I think this probably is. Anecdotally there is massive crossover between religious individuals and climate change deniers among people I know.
And only 33% of people in the world are Christian. Other religions might have an even larger fraction of climate change deniers.
I doubt it correlates as well. American Christian 'leaders' (specifically Evangelicals) have strategically married their religion and conservative talking points. It (climate change belief) is not as associated with identity in other cultures.
