I agree with a lot of what you say here. but i also think that people like Ross McKittrick, who feeds the fire by propping up and shilling for businesses like Exxon, are leeches on society. I have to wonder how much lack of consensus comes from the greed of politics and business, and how much is a total misunderstanding of the mechanisms of climate change. Everyone points to CO2 and says "oh but that's plant food" yet fail to understand that balance is imperative when regulating any organic system. We only need to look at the human body to know too much or too little of an element can throw the body off kilter, yet when it comes to the earth we fail to understand the same principle. I think it's important to look at why alarmists and skeptics are saying the things they do. I can forgive ignorance. I cannot let greed and power go without speaking out.

I found this article a week back that touches on what you're talking about - the stuck in discussion yet doing nothing, because no one can agree -this tbh. and i think that this is one of the reasons theres so much vitriol, because while we have lack of consensus, the clock is ticking.
