Let's say global warming will hit its peak by 2020 (warmest earth). You want to say this in English, your prediction goes like this:
If global warming continues to the future, by 2020, it will have reached its peak, I believe.
This is only an estimation, meaning not sure. Am I correct to use "will have+participle" (present future) or should I use "would"? -using "would" may fit more as for the prediction thing is concern, BUT, from what I know, there is no such thing as "would have+participle" when you want to express something that will happen in the future. Right?
