All four countries are governed by right of centre legislatures in which denialism runs deep. All four countries are also big into fossil fuel production. All four countries have an overall right of centre media that is collaborative with right wing government and energy producers.
What this chart also reveals is that, even in the United States where denialism is at its strongest, a solid majority of the public accepts anthropogenic global warming/climate change. In all four countries, the government is plainly at odds with its people when it comes to climate change.
Well if our Anglosphere isn't working for our peoples, who do these governments serve? Oh sorry, I don't know what I was thinking. Forget I asked.
