You making a false equivalency. The skeptic side is NOT producing credible evidence. They are instead creating a circle of confusion. The Republicans are the same party that deny human evolution, climate change, etc. They produce nonsensical theories called Intelligent Design to push an agenda to reach religion in schools. They are the same party that declares "legitimate rape". Both sides are NOT correct in these cases.
A scientific consensus exists on manmade climate change just like it did with the correlation between smoking and increased cancer rates but that didn't stop the tobacco industry from producing "credible data" to refute it and create the circle of confusion decades ago.
While we all still wonder about manmade climate change, it's interesting to see studies like this:

I suspect you won't get an argument from anyone living in California about manmade climate change as they are too busy wondering where they will get fresh water from in the next 5-10 years due to the worst droughts in modern history in that state.
