global warming is indisputable. The reason for it can be disputed, and so can the expected duration and severity of the consequences, but the trend (rising average global temperature) has been demonstrated statistically with reliable evidence.
I reject the term "evolutionism" and suppose that you mean "the theory of evolution".
The theory of evolution is - as all scientific theories - based on scientific evidence.
Some of the things predicted by the theory have been observed in nature. So: some aspects - some tenets, one can say - of the theory of evolution are "scientifically proved", demonstrable fact.
Certainly it is NOT true that the entire theory has been proved to be true. Of course that is exactly why it is still called a theory. Some people who don't understand such things will object to that statement, and all I can say in reply is: look it up.
