 Question number four, we're going to look at what happens if we drastically reduce all of the different fossil fuel energy sources. So we're going to turn on, well first we'll do the control run. So we run that and see what the emissions are now. We're gonna follow the instructions here and turn on all the coal, oil, and gas switches and I'm going to reduce them all to a new fraction of 0.5. That's five percent. So each one of them will make up five percent of our total energy sources. Then we're not going to change per capita energy population limit at 12. Start time for reduction at 20. Adjust time is two years. So we do that. Run the model. We see results here greatly reduced emissions so that in 20, 2100 we've got 5.74 gigatons of carbon removed and so you just subtract 5.74 from 29.57 to get the answer, which is going to be 23 points something. So that's the answer for that.
