What is still an area of research is "how much"? There is still a considerable range in the estimates. Some of the estimates would be problematic if they verified. The "sky is falling" cry come from left leaning politicians and the press. The scientists working this area are simply reporting what the current state of the science is indicating. There are many international teams working on this. I fail to see the point in attempting to disparage scientists you don't know. Isn't this the same thing you accuse others of doing? Full disclosure - I am a retired atmospheric scientist and developed numerical atmospheric models.

In which case I know you are aware that the most important "greenhouse" gas is not CO2, but water vapor. Hence, after the rise of the Himalayan and Rocky plateaus about 60 million years ago which act as heat sinks by catching atmospheric moisture and creating rain, the planet is about 10 degrees cooler'
And yes, while paleoclimatologists study the past, we don't have any psychic climate experts to predict the future, so to a certain extent we look at the past to create future "models". And yes, these models do vary. I am not "disparaging" those scientists as much as I am concerned that the grant and political climate (pardon the pun) may bias them. Let's face it, when you know that if you conclude and then publicize your model that shows anthropogenic climate change is a myth, you are done receiving any federal grant money, there might be some bias.
If I am way off base on this, let me know, since you clearly have more expertise on this subject than I----as you know, I don't care for amateurs meddling in my field of expertise either.
