One only needs to look outside to see the climate change and only a basic understanding of physics is required to understand the link between human activity (GHG emissions, deforestation, etc.) and the warming of the atmosphere.
The problem isn't the lack of explanations for the truth, it's that the truth isn't as appealing. We don't want to believe it's our fault, and blindly going against consensus seems to be the popular thing to do this century. People have a huge incentive ($$) to make this content and a huge incentive (feeling superior, free of blame, etc.) to believe them. Where is the incentive for believing science?
