It's not hard to accept - I was a climate hysteric from third grade. They had me do special projects including writing a book on how devastating global warming would be. I've posted about it on here before.
It was hard for me to see that I had been indoctrinated in an ideology which was not based in reality and intentionally created fear in order to gain more power and influence. I'm glad that's now where I am at.
I reccomend you read fossil future. "Science" needs to be paired with scrutiny and logic, and the book does a good job of that.
