I understand that "so and so will happen in a few years" (which means so and so will happen with after a few years pass) is different from "so and so will happen within a few years."
It seems to be that the above rule does not apply to the following sentence.
"Decisions we make in the coming years will
profoundly affect the natural world."
Does the above sentence mean "decisions we make with an elapse of the coming years" or "within the coming years."?
