I think all the scientific evidence indicates that we'd be on a long ~50,000 year slide into a new ice age right now, except that human ingenuity in the pursuit of energy resulted in a massive injection of fossilized carbon into the atmosphere in the form of coal, oil and gas combustion. However, if the goal was to head off the next Ice Age, all the scientists agree, "Mission Accomplished!" Probably best to eliminate fossil fuels from the energy mix immediately, don't you think?
