Integrated assessment model is a tool used to launch integrated assessment. Although these two terms are very similar but are two different activities and are not identical. Integrated assessment model is base on assumption and information to compute how the climate change behave in a policy making. Integrated assessment model are a mathematical model that it use number to calculate the climate change cost and benefits.
Introduce the Integrated assessment model
Integrated assessment model created by the universities 's researchers, government departments and private research companies. Integrated assessment model gather information when there is a set of data researched from standard research activities, information and to …show more content…
As the model has different underlying assumptions such as in rate of GDP level, population and use of fossil fuel. The model assume the variable with climate change has different relationship upon to the normal thought (SEDAC, 1997). This is an advantage for the decision maker to make an judgment for the problem not just base on their well-known knowledge but to think of any other way that could be possibly happen. The problem of climate change has no such a standard framework to explain and to be solve. It is important that the decision maker view the problem in different angle and different way so that they can come up with a judgement in a way that is better and suitable for solving the problem of climate …show more content…
For example, in America, the policy made in the country use democratic way, which the policy making are not determine by the decision maker but through many other parties. Even though the model are proven to be a very accuracy model, it will not have great influence to the process of decision making in global climate change. To have comprehensive policy in global climate change is a very difficult challenge and it is unlikely to be achieved, even though integrated assessment model can predict very accurate cost and benefit in global climate change that produce a ultimate best solution, different countries has their own policy and aspect in climate change, the model mainly focus on global climate change, decision making will base on national and international level, to achieve globally emission reduction needs very limit restrictive reduce in number of green house gas each country can produce, thus it is unlikely that model can be used to help making policies in global where connected to many different countries. Because of these reason, U.S.A Economist Ronald D. Brunner thinks that instead of using integrated assessment model in evaluate what decision making, decision maker should put their effort rather in experiment, increase knowledge and better understanding in
