Answer:
E - Ridicule
Step-by-step explanation:
Process of elimination:
The phrase has a sort of ring to it "Globally" and "Locally" So it has meter and rhyme, and can not be A.
The sticker is referencing the greater issue of global warming and climate change, which is allusion, so the answer can not be B.
The irony in the sticker is that although global warming is about an increasingly warmer earth, this are still harsh winters. Thus the answer can not be C.
The bumper sticker has ambiguity because of its multiple interpretations. So not D.
Finally the answer is E because they are not making fun of anything, instead raising awareness.
Hope this kind of made sense :)
