Dear Dr. Mardani,

The topic is very interesting. Yes. The impact can be very important specially if it can cause domino effect. The following issues can create a wicked problem.

1) The complexity of the problem. We do not exactly know what are the drivers and how they interact with each other.

2)The problem needs to be dealt in different levels. Local-scale actions can have impacts on large scales and vice-versa.

3) There are numerous sources of uncertainties.

4) Optimization methods might fail to answer this question.

5) It need many interdisciplinary scientists.

6) ....

Dear Mohammad,

Thank you for your explanation, I need to your suggestion by introducing a technique, model or method for predicting some issues regarding to global warming for next future years for example 5 years, do You have any suggestion?

Thank you

Dear Dr. Mardani,

My suggestion is using system dynamics methods. If you need more suggestion you can email me.

I think that a prediction for the next five years is impossible for various reasons:

1) Climate change is extremely complex; so complex that we know that we do not know everything that plays a role.

2) While climate change is happening climate variability does not disappear. Does means any climate is still happening within a range of weather ranges which can enhance climate change aat times or mitigate it.

3) I doubt that a political event like the withdrawl of the USA from the Paris agreement can be exactly measured in future climatic changes. One can assume that such impact exists, but to exactly measure it can bring only approximate results, partly for the reasons meantioned above, partly for the mechanisms we are not even aware off.

Dear Mohmmad;

Thank you for your respond and your suggestion, kindly, please send me your suggestion to my email, this is my email:

Dear Eberhard; 

Thank you for your comments and your opinion, I think withdraw of the USA from the Paris agreement is not only political issue.

One of important goodwill of the Paris agreement includes the green climate fund for transferring money from rich countries to developing countries for building resilience, mitigating and adapting to the effects of climate change. Therefore, by withdrawal of U.S from this agreement we lost the financial support of this country. According to Paris agreement report, the U.S. has pledged USD 3 billion for this agreement and till now only has delivered $1 billion but seems unlikely to add to that.

The U.S. leadership was essential in Paris. The leadership of the U.S was essential in global climate efforts, as the U.S. is among the top two emitters of greenhouse gases and a leader in the world economy and in technological innovation.

However; thank you very much for your opinion. Need to know more opinions of scholars regarding to this issue.

Dear Colleagues,

It is difficult to follow all these endless talks about climate change. It is another of the same.

Climate change is an integral part of the evolution of the Earth; its “face” is shaped by the precipitation and temperature and by the endogenous forces.

This is my suggestion:

Use your intellectual and manual commitments to keep your world clean and tidy and do not put it into the hands of image neurotics who exactly know what the rest of the population has to do.

Be an example.
