"A new 23-country survey conducted by the YouGov-Cambridge Globalism Project found that America has the highest percentage of climate denial among first-world nations, behind only Indonesia and Saudi Arabia in all the countries surveyed. A total of 13 percent of Americans responded that “human activity is not responsible at all” for climate change, 5 percent denied that the climate is even changing, and a further 13 percent did not know whether the climate is changing or people are responsible.
The good news is that those 2018 numbers were at record low levels.
Climate denial in the United States appears to be shrinking.
In evaluating why climate denial is so much more prevalent in America than other wealthy countries, it’s important to consider its demographics. In the 2018 George Mason and Yale survey, just 42 percent of conservative Republicans accepted that global warming is happening, and only 28 percent correctly attributed it to human activities. Older Americans are also more likely to deny human-caused global warming, especially white Americans over the age of 55.
Another recent survey found that Republicans who watch Fox News are more than twice as likely to deny human-caused climate change than Republican non-viewers, and 62 percent of Republicans watch Fox News. Consistent with the demographic breakdown of American climate denial, Fox News viewers are overwhelmingly old and white, as are climate deniers."
