Well, let's do the math. If CO2 levels continued to increase at exactly the same rate as they have for the last 50 years at 60 ppm (320 in 1960, 380 today), then we'd go from 380 today to 3,800 by the year 4860. Nothing to worry about. However, what is happening in reality is the amount of CO2 being pumped into the atmosphere is actually accelerating, which means we have a compounding of the impact. So let's do the math. If we see a 1% increase per year acceleration, then we will reach 3,800 ppm by the year 2046 or so. That's only 37 years away. If the acceleration is only 0.1% per year, then we have a bit longer. We'd reach 3,800 ppm by 2115. So if it turns out that humans are the most significant cause of the CO2 increases we're seeing, then it would indeed be a real problem to not do anything. It would be tantamount to driving our car towards a brick wall. Doing nothing means we get there faster. Doing something means we at least take our foot off the accelerator. If it is manmade, then I'd prefer we not only take our foot off the accelerator, but we also put our foot on the brake.
