A recent article summarized "Four big reasons why deniers started believing in climate change”
The biggest reason was a slow acceptance of clear scientific evidence.
People tend to reject the validity of scientific evidence when it conflicts with their deeply held world-views.
For conservative individuals, who doubted climate change, one example article was far more effective at convincing them that humans caused global warming because the science was presented in an existing pro-industry narrative.
The solutions proposed for climate change are pro-business, pro-military, pro-national security, pro-economy, and pro-jobs.
There are now more people working (over 100,000 & growing) in renewable energy jobs than in all the oil industry that is continuing to cut jobs and had a $67 Billion loss in 2015.
