If we assume that global emissions will continue to grow at the current rate, or increase exponentially, the situation appears more dire than it really is. Renewable energy is getting cheaper every year, and fossil fuels are getting more expensive. Some sources of c02 fixation are more efficient when the c02 levels in the air are higher. Also as energy gets to be cheaper overall, the cost of sequestering goes down.
