Scientists believe that Earth is becoming warmer. This idea will become unacceptable over time if scientific evidence supports a new idea .

Explanation:

Scientists assert events and situations based on scientific evidence, which is the set of elements that prove that a scientific hypothesis is correct or incorrect. There is now scientific evidence to prove that the earth is getting warmer and that it will get hotter in the coming years. Because of this evidence, scientists confirm that we are experiencing global warming.

However, this idea will be discredited if new scientific evidence emerges proving that this idea is wrong, or supporting a new idea. In this way scientists will stop affirming the occurrence of global warming and defend other ideas.
