Climate Change And Denialism: Is Science Ever 100 Percent Certain About Anything?

There are some who are climate change deniers. No amount of evidence will ever convince them anthropogenic global warming is real and happening right now. Then there are others who may choose to play the role of devil’s advocate, even if they fully accept climate change is real. When a UN report shows 95% certainty that climate change is real and humans are the cause, the devil’s advocate says there is still a 5% chance they are wrong, so therefore people who say they are skeptics (including out-and-out deniers) have a valid point. — No, they don’t, and here’s why.

Climate Change: The False Assertion Of ‘The Science Is Not Settled’

I have to get this out-of-the-way right off the top: In science, nothing is ever “settled” in the sense people think when using that word. It’s the nature of science to always question, but there are things for which there is overwhelming evidence and we might sometimes refer to these things as facts. But if you’ve heard conservative media reports on climate change, then  surely you must “know” the science on climate change is not yet settled. Fox News pundits and other right-wing hacks point to scientists who say humans are not responsible for global warming, or that the globe isn’t actually warming at all, its cooling.
