Study: ‘Rich Republicans Are the Worst Climate Deniers’ – Published in journal Climate Change
'A new study in the journal Climatic Change has identified a closely related phenomenon. Call it the "rich idiot" effect: The study finds that among Republicans, as levels of income increase, so does their likelihood of "dismissing the dangers associated with climate change." But among Democrats and independents, there is little or no change in climate views as levels of income increase or decrease.'
