Effect of global warming seems to be uppermost
At a superficial level, there is much debate about whether global warming is real and, if so, whether it is caused by human activities.

A further, closely related key issue is that those who could suffer most from global warming and climate change are the future generations, and they are powerless to affect what we do now.
