Lessons > Curb Emissions > For Your Consideration
You've seen that the rate of increase in fossil fuel use would have to stop in order to keep atmospheric CO2 below 550 ppm, despite a projected increase in energy demand (currently 2% per year, though it rose to 2.5% during 2000-2010). Consider what this means in real terms. What non-carbon-burning energy sources could make up the difference? And how fast would their adoption have to increase? You will explore this question in the Energy lab.
Considering the extra carbon created by humans, how might it be possible (or is it?) to generate more means of recycling carbon?
