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.

The correct answer is b.
Hardly, as an adverb means "just", hardly, in this context is acting as a limiting modifier of the word ever. <em>Hardly ever</em> means very occasionally. We may use words like it to emphasize how infrequently an action takes place. You should note also that there could be other ways to give quite the same meaning, like when you use <em>rarely</em> or <em>seldom</em>, but, hardly ever has also a <u>negative</u> connotation.
