A scientist's belief is called fact, and these beliefs change over time.
No.
Explanations of facts might change, when new facts don't fit currently accepted explanations. That's called learning and making progress.
But facts are facts and stay facts.
When a theory is discarded and replaced by a better theory - the facts are still the facts.
Take the fact of the day/night cycle for example.
It is a fact that we observe the sun rise on one side, move accross the sky and set on the other side.
Wheter we explain this fact through geocentrism or heliocentrism, is irrelevant.
The facts are the facts are the facts.
The day/night cycle didn't change when we adopted heliocentrism and discarded geocentrism.
Observable reality is what it is, no matter how we explain it.
So indeed, it is a fact that CO2 is a greenhouse gas. It is a fact that we pump massive amounts of it into the air which caused a doubling of this greenhouse gas in the atmosphere in just 100 years.
These aren't beliefs or hypothesis or theories. These are facts.
