It depends on how you worded your essay and what your views on global warming are, the way I would word it is "in conclusion global warming is real and changing drastically every minute, and we don't fully know exactly how it will affect the world long-term" that's one way you can say it.

and feelings as he copes with his grief over such a long period -
including wrestling with the big philosophico-scientific questions of
his day.</span>
