Not fake.. climatology is still a relatively new science so models aren't accurate enough nor is enough understood to make any significant changes that would in all likelihood adversely affect an economy.
As I have said in the past, you may not believe it but people have been thinking about planetary climate more than a century; in particular the idea that doubling CO2 will significantly increase global temperature originated in 1896, so this idea have survived a century of scrutiny.
The first comprehensive assessment of climate as in 1979 concluded that the warming due to a double of CO2 is likely to be 1.5-4.5 degrees. Most recent iteration of the IPCC report is 2.0-4.5 degrees. This estimation is obtained not just from climate models, but from current observations, and many paleoclimate data. So even if you discount climate models (which is unjustified), observations suggest there are significant consequences if fossil fuel use continues unabated.
Of course mitigating the effect of global warming will have economical consequences, but so will a 3 degree warming. Continuing to toe the "uncertainty" line while ignoring existing evidence is not a prudent move.
Problem is, green nuts are getting in the way of climate advances (which is a problem with other sciences as well when these people get their slimy politics in the way) trying to end debate by injecting their politically contrived agenda into what should be politically neutral advancement. "Shutting people up" as put by another poster on this page somewhere, is just one example of many.
That's a baseless assertion. "green nuts" (whatever that really means) don't do research. They don't review grants. They don't making funding decisions. They don't run scientific journals, nor do they run scientific conferences.
All activities involved in advancing science are done by scientists, so unless you are implying that climate scientists are green nuts, how exactly are "green nuts" getting in the way of science?
On the other hand there have been real impediments to the advance of science: frivolous FOIA requests and death threats from people who are certainly not "green nuts"
