 This is the interface to the model that combines a global economic model with a carbon cycle model and a climate model we've already looked at the climate model and the combination carbon and Climate together with an emissions model. This one includes a Model that's based on on William Nordhaus's work That represents a global economy so it links all of these things together now there's only really one thing that you're going to interact with on this model in in terms of Making changes and that's this this some graphical function called ECR. This is the emissions control rate and If we click on that We see this graphical function It's something that varies from zero to one and if it's zero it means we're doing nothing really to control emissions of carbon From burning fossil fuels if it's one it means we're going all out. We're going to spend whatever it takes to You know remove all the carbon emissions from from our economic activity So initially it's set to to be something very close to zero. You can alter it by clicking at different points here and Create a model that that takes us to this very very, you know clean Energy situation here and in the future that this this line here at the edges the year 2200 The one on on the far left is the year 2000 and then in between in the middle. There's 2050 2100 and 2150 so you're going to be given a set of of instructions for A scenario for how this ECR is going to vary and you're going to modify this graph according to those instructions you get being a hit okay and then you're going to run the model and when you run it You see it gives you all sorts of outputs after a while including human emissions global temperature in total there are something like 17 different pages of Features in the model that are graphed here So you're going to have to sift through these these pages and find the right parameters and then you record things like the ending value of the The sum of the relative per capita consumption, which is An important parameter in this model that's explained in the lab activity. So that's it
