http://www.climateinteractive.org/tools/c-learn/simulation

Here is the challenge: what changes could you make to limit the average global warming to +2.0 degrees Celsius by 2100? How you get there will be your choice. The simulation offers you advanced features to alter the model (see in the menu at the top where it says ‘simulation’ and go to ‘assumptions’). This model has certain assumptions for the basic physical processes of global temperature (including such factors as ocean mixing, climate sensitivity, Biomass loss from afforestation, etc…). If you want to you can alter these assumptions, but keep in mind that these parameters are probably set based upon empirical evidence and scientific measurements – so as a scientist you’d have to have a pretty good justification for altering them. But it’s worth thinking about. Every model is based on assumptions – and if those assumptions are incorrect the model won’t be of much use. Sometimes little errors in our model assumptions can have big effects on the accuracy of the prediction – just some food for thought as we go about exploring the simulation (and also consider the intense political debates on this subject). Solutions to the problem of global warming will involve considerable investment and economic sacrifice world-wide, so it’s no wonder that it has become a political issue.

Here is what you will do:

With the goal of limiting global warming to +2.0 degrees C, you should tweak the numbers for the six key players (US, EU, Other Developed countries, China, India, Other Developing Countries) to get to +2.0 degrees C or less by 2100. How will you do it?

Some suggestions:

Try changing ‘Emissions Peak Year’ to some year earlier than 2100.

Once you change the Emissions Peak Year, you can change ‘Reductions Begin Year’ and then set the level of reduction per year (some percentage)

Try preventing deforestation (by altering percent) or increasing afforestation (also by percent).

Once you have played around a bit, you should write up a brief (1 page report) on the project. How did you limit the increase in global temperature? Were there any key methods that altered the balance in your favor? Once you describe what you did, I want you to write about the actual practicalities (in the real world) of what you did. In other words, would it be possible to implement the changes you made in our world of real people? What economic sacrifices would have to be made by different countries to achieve your plan? What would be the biggest challenges politically in implementing your goal? Do you think your plan would have a chance of being enacted in our real world? Other things you might write about in your one page report could include what your energy sources of choice would be? Would you use all renewables? Nuclear power? Would poor countries be allowed to burn coal at all? These are just some suggestions for where you might go with this.

You should include:

A data table showing the years and percentage changes you used in reaching your goal (just like the one in the simulation)

Two references to popular science articles about the challenges of slowing down global warming.

Explanation / Answer

Answer:

As increasing temperature around the world are the biggest challenge for the society. The developed countries and developing countries are utilizing more natural resources such as fossil fuels. But developing countries are more dependent upon these natural resources therefore graph of increasing carbon per year is more for developing countries. Hence, we should control the limit of carbon emission for developing countries as well as for developed countries. And besides this we should also control the deforestation for decreasing the temperature for environment.

To decrease the temperature globally we should walk along with all world in terms of using carbon emission product.
