Because the geologic record doesn't support their conclusions, because they don't actually discuss the earth's climate or what drives it, because their "science" is in reality nothing more than computer modeling, because the planet is closer to extensive northern hemisphere glaciation than it is a greenhouse, because the last 500,000 years has been extremely cold and the trend is for a cooling planet, because they stoop to stupid severe weather arguments, because they drastically over state the danger of a runaway greenhouse planet, because the US isn't the problem, because this is about money, because I don't blindly accept anything. I could go on for days but that's enough for now.Are you a climate scientist? If not why do you think you have special insight that allows you to gainsay the findings of literally thousands of independent researchers over the last 60-100 years?
I'm actually quite curious. If you prefer the work of Lindzen or Curry to the vast, vast, vast majority of the earth's climate experts you are effectively betting against the house. Not because you have some inside knowledge, but rather because you prefer their position.
Obviously I don't know you, but I rather assume you are at least like me and that means you are not a climate expert. I've been lucky to work in the earth sciences and be around a lot of folks who were, but I'm not myself. So in a sense I'm forced to defer to those who know better than I do.
I assume you are likewise hindered.
So when are you going to tell me what drove temperature trends before the industrial revolution and why they still aren't doing so now? You do realize our planet is 2C cooler than in the past with 120 ppm more atmospheric CO2, right? Why isn't it warmer now?
