Complexity is a common attribute of the world that we live in. Although the recent advances in different technologies have made our life easier in many aspects, these advances also bring new challenges that add to the overall complexity in this world. A typical example in this respect is global warming which is a direct consequence of our habits to consume products that require the use of large amounts of energy. Without a doubt, global warming has already become a very complex environmental problem that requires urgent and coordinated actions by international institutions if we want to save our world for future generations.
