1)meaning of sentence : The forest is will be decrease graually in Europe and other contreis it's not good.
2)The govenment have to prepare the Grobal warming. It is brings to us bad effect.
The sentence you quoted is very confusing. It could mean one of two things:
1) Data on forest productivity and global warming suggest bad things to come.
2) We don't know what lies in store because the data itself isn't very good.
I think it means the latter; we don't have very good information about forest productivity costs or global warming.
If so, I'd say that's true to a point - but we certainly have more than enough data to prove that global warming is real.
"The govenment have to prepare the Grobal warming."
The government HAS to prepare FOR global warming. Or you could say, "The government must prepare for global warming," OR "The government should prepare for global warming."
"It is brings to us bad effect."
This sounds very awkward. Here are some other ways of saying it:
It threatens us in many ways.
It is already causing trouble.
It is already affecting millions of people.
It is a serious problem.
