It's politics who's trying to use science (or far more frequently trying to deny science), not the other way around.
Here's science : our climate is changing and that change is mainly (and probably exclusively) the result of human activities. What politicians or anyone with a political agenda do with that scientific knowledge has nothing to do with science.
Don't think so small. Many folks have agendas. Schools, politicians, scientists, news shows, etc. And said folks will collaborate to ensure continuation of their agenda. Here's a clue......watch where the money flows. (this qualifies for whatever side of the fence you are on).
See how you even try to lead the reader to give credibility to your view? First you say for fact that your statement is science, but give no source. You then lead the reader to your hypothesis that it's all humans that are the exclusive cause for the climate to change. This is subjective science. And that's the problem and gives the ability on both sides to massage the data to suit their needs.
Frankly when it comes to such divisive topics, I always think that the truth is more in the middle of the data floating around.
