Not true. El Nino (increases CO2) and Albedo (long term - it's decreasing) are problematic issues in this area. If it's settled science why bother to even consider other factors? Doubtful if humanity would survive the catastrophe resulting from a global interdiction of the kind you suggest and we're not dense for understanding that. Greening of the planet (plants need carbon to grow) which has contributed $trillions to world productivity would also taper off. Moreover the related sulfate emissions actually mask warming - reductions in these emissions is related to some of the recent temperature increases. So you could likely get a temporary spike in warming. All that said, there are sensible routes to reducing human influence on the planet.
