In a perfect world yes, but lots of scientific disciplines are heavily influenced by politics and public opinion in terms of funding, University support, etc. We can't pretend it doesn't matter
It doesn't matter to the supporting data. Thermometers don't run off of opinion. I guess that is what we need to convince people? lol
The money to fund the thermostats may depend on opinion.
In a fantasy world complete with international conspirators with god-like powers..... sure. If you don't like my use of the word "fantasy" then by all means provide some evidence.
