It doesn't matter whether it's 97% or 9.7% on global warming because there is no debate about the effects of pollution and ecological destruction on humanity and the planet.  In my book, the back and forth on global warming is an intentional distraction from the reality of pollution and ecological destruction.  I never engage in global warming denial.  I pivot the conversation to pollution and ecological destruction.  Cure this one and you have greatly impacted the amount of human action on global warming.
