am just trying to understand why some people in society are still skeptical about climate change even though there are scientific proof.
Well if you mention what proof it is easier to answer
and I think they mainly doubt why things change not that the change they see is real.
The main problem is that the climate always change over long periods of time, so there is always something to blame. We have gone from hot climate to ice age and back so many times, it might not be a problem many could arguee.
Can you really prove that the amount of dimming vs the amount of heat absorption is heating us, that no natural causes is to blame(sun etc)?
The next thing comes down to simple psychology, human brains do very bad with change, especially for the worse, and we rather blame nature then accept being part of said change.
We also must come to realization of the situation, something that requires humans to read up on it and focus on it, which they most likely won´t. If media gave them a false view, it is even less likely they will ever come to see the situation with pure logical thinking or even read sources stating opposing facts :S
Good luck!
