Reddit mentions of Why We Disagree about Climate Change: Understanding Controversy, Inaction and Opportunity

For one of my classes, we are currently reading Who Speaks for the Climate - Boykoff and Why We Disagree About Climate Change - Hulme

They are great books, gives good insights to the topic and how it's portrayed in the public. I'm sure you can find cheaper editions as well, or PDF files.

Also, both definitely lean towards the idea of it, the authors are not really skeptics

This, Why We Disagree about Climate Change, might not be quite what you're looking for, but it's an interesting read. It's a combination of science and geography.

What proportion of people, regardless of whether they believe there was a global flood or not, do you think have taken the time to educate themselves in those fields of study to a degree where they can adequately assess those studies for themselves?

That's your answer. People for the most part base there views on authority figures, and different people in different social contexts invest different people with that authority.

In the case of the flood, it's a thoroughly unimportant issue. But it's an important point to make given its practical consequences elsewhere; I'd recommend the excellent Why We Disagree About Climate Change by Mike Hulme as a starting point. It's simply no good feeling superior or believing that one's opponents are uniquely stupid on the issue, that's an approach that prevents action on the issue.
