what are the impact of ethics and justice in climate change (global warming)?

Answer 1

Climate change won't have any direct affect on ethics or justice as these are human characteristics and codes.

There may come a time in the future when governments and large organisations have to implement plans that are ethically questionable. For example, if drought, famine, flood, desertification and other factors drive millions out of Africa and Asia it raises the question as to whether America and Europe have a moral and ethical duty to open their doors and admit these climate refugees. Some may argue that there isn't the space or resources to accommodate more people, others may argue that the problem is largely caused by Europe and America and as such we have a duty to care for those who have been affected by our actions.

In such a scenario there would undoubtedly be involvement from the judiciary but it's really a matter of speculation as to what may or may not happen.

Answer 2

To change climate on a global scale will require a tremendous amount of power, concentrated and coordinated. The opportunities for abuse are equally tremendous, especially when you consider the vague amount of warming attributable to man and the even more vague techniques to remedy this excess contribution.

Answer 3

It seems to be a political question rather than a science question.
I don't know why.
