anonymous · Answer

1. Just because it is not discussed in a forum does not mean the theory will get rejected.

2. If scientific idea supports a new idea that earth does not get warmer, then that works! 

3. Another hypothesis that might not be true is not going to change the idea.

4. A new instrument that is invented might even support the idea. The instrument might measure the temperature to be hotter every year.
