 Questions 6, 7, and 8 all have to do with a model scenario in which we get the total emissions of carbon to more or less stabilize for a good part of the model run. So to do this experiment, first we'll run the basic model, the control version. So just hit the run button. Then we follow the instructions on the question to set it up to get to a scenario where the emissions more or less stabilize. So to do that, we're going to turn on all the switches. We're going to set the new fraction to 0.15. That would be 15% for each of these. So that's a decent reduction in the overline, some fossil fuels. We're going to make the transition and be a little bit slower. So we'll move the adjust time to 10. And then we're going to change the per capita energy history. And normally when you open this, you just see this graph. If you click on the table here, you see individual entries and we're going to alter this as follows. So 74 there, 72. And this is 70. This is going to be 67, 64, and 61. This is just another way to alter that graph. So okay. And you see that graph is declining slightly over time. Keep the population limit at 10. Okay. So now we'll, that's 11. I want to get it to 10. There we go. Now we'll run the model. You can see that that gives us this emissions history that's more or less stable. So that's staying the same. And you can see what the emissions are in the year 2100. Gets us down to 6.14 gigatons of carbon in the year 2400. Now what kind of a temperature change does that cause? That's a question number seven. So we can look on page three of the graph pad here. So the temperature change in the year 2100 is 1.91 degrees as opposed to 3.92 for the control version. So that's your answer to number seven. And then number eight asks this question of, so we stabilize the emissions. Does the temperature stabilize in the CO2 concentration atmosphere? Well okay. So you can see right away the temperature does not stabilize. It continues to rise. It's just not rising as fast as it does in this control case here. So to look at the at the PCO2, we go to page nine of the graph pad here. And there you see the CO2 concentration of the atmosphere starts off at about 400, a little bit less than that in 2010. And then by the time you get to 2100, we have a CO2 concentration in the atmosphere in this altered version of 484. And that's price per million as opposed to 851 for the control version. But look, even the the CO2 concentration, that doesn't stabilize either. That continues to go up. And so it's not enough to just stabilize carbon emissions. Clearly, we need to actually get them to reduce if we want to bring the CO2 concentration down to a lower level and kind of keep it stable. And if we do that, CO2 concentration and temperature are very closely linked together in this model. So they'll generally do more or less the same thing.
