CERE:s Kelly de Bruin gav sig av till Montreal i Kanada för att skriva ett kort paper, men entusiasmen tog över allt mer och en ny modell fick se dagens ljus: The Mitigation Adaptation Geo-Engineering Economy (MAGE) model. En modell att styra dem alla, eller ja, åtminstone begränsing av och anpassning till klimatförändringarna, samt geo-engineering. Här berättar Kelly mer om hennes besök i Kanada och modellen.

Last year I was very happy to hear I received a grant from the Per and Eivor Wikströms fund to go to work with Professor Olivier Bahn in Montreal. Professor Bahn is head of the Department of Decision Sciences at HEC Montreal, which is a French-language university institution offering internationally renowned management education and research. We have enjoyed working together for several years and this was a great opportunity to increase our collaboration.

This May, 2016, finally the time had come to go to Montreal and work together intensively for a month. We initially intended on writing a short paper including uncertainty into a previous framework we developed, however, when we started working our enthusiasm took over and we embarked on a more ambitious project. We decided to fulfill our long term goal of developing our own integrated assessment model (IAM). IAMs are applied economic models that describe the long term relation between the climate and the economy. They are often used to assess climate policies such as mitigation, adaptation and geo-engineering. Each existing model, however, tends to focus one specific policy and models that policy in detail while the other policies are represented rather simplistically in the model.

We want to create a model that includes all three policies (mitigation, adaptation and geo-engineering) in as much detail as possible, so that all policies can be evaluated simultaneously. We find this an important issue as to make sound policy recommendations or conclusions all option should be included in your analysis in a meaningful way. This resulted in the birth of the MAGE model, that is the Mitigation Adaptation Geo-Engineering Economy model. During my month in Montreal we made a lot of progress in our scientific work and I am happy to say my French also improved marginally. We were able to develop the basis of the MAGE model in Montreal and will continue to develop the model further. We have many extensions in mind for this project and plan on involving PhD students to help expand the model. Hopefully in the future the MAGE model will become a model to reckon with, involving many collaborators and resulting in many scientific papers.
