No, the climate models the businesses and politicians found acceptable are watered down models that showed that we had a lot of time before we needed to make changes, thus letting the businesses and politicians pass the buck.

The more aggressive models and the scientists that supported those models lost funding and were shouted down. Some of the models that got buried fully expected the changes to be happening at the pace we are witnessing. Some of those models said that once the permafrost started to thaw that it would release so much carbon, methane and nitrious oxide withing 10-15 years that the earth it's self would surpass human generated output. If those models are correct then it means we've passed a climate tipping point and nothing humans can do will reverse what's been set in motion. Event if human greenhouse gas output is reduced to zero overnight, the earth itself is now driving the changes to the climate.
