What a charmingly complex, political, and heated topic.
I will enter the fray with foolish ignorance, stating, "Hey, I heard CO2 concentrations is at more than 400 ppm, which is about 30% higher than any of the former variations we can measure over the last 800,000 years. And we can tell from the carbon isotopes that most of it is from fossil fuel burning."
CO2 produced from burning fossil fuels or burning forests has quite a different isotopic composition from CO2 in the atmosphere. This is because plants have a preference for the lighter isotopes (12C vs. 13C - See more at: http://www.realclimate.org/index.php/archives/2004/12/how-do-we-know-that-recent-cosub2sub-increases-are-due-to-human-activities-updated/#sthash.VQ8yuQE1.dpuf
Hypothetically, let's say there are two possibilities: True or False that imminent severe anthropogenic climate change is in full swing.
If False, then what? Then we continue to build roads, drive cars, raise more livestock, burn coal, sit in traffic, clear more trees for farm land, etc. because people have to live and the economy must continue to grow.
If True, then what? Then we will continue doing the exact same things until agricultural failures of coastal flooding cause an economic collapse.
We ain't gunna change. We will continue to grow or we will collapse, or until we collapse.
