For the people saying it's 100% not settled: Okay.  Fair enough.  It's not.  But you can't really say that, and then not be open to the possibility that climate change is being caused by humans.  It's fine to be skeptical.  Most of us aren't scientists.  It's another to be an outright denier. The fact that it's not settled means that you can't just accept one outcome, and then proclaim that the other side is wrong/lying/a hoax.


And of course people who do think climate change is being caused by humans have to deal with the people who make ridiculous arguments that aren't based on science at all.  They make stupid arguments like "It's cold outside today!"  and "It's snowing!"  It'd be like saying "You know, World Hunger is solved.  I had a burrito for lunch."  


The fact that it's not settled yet means that you can't dismiss the possibility of it happening.  It's okay to have questions and concerns.  It's not okay to dismiss 97% of the climate change scientists because of partisan politics.  People like to dismiss climate science as similar to astrology, but that's pretty far from the truth.  Even a non-scientist should be able to understand the difference between the two.  Weatherforecasting is much more accurate than most people would like to admit, and there's a major difference between climate and weather (which some deniers will never get drilled through their heads)  


The real problem is that the so-called skeptics/deniers are basically deciding that it's settled, and then saying it's not settled.  They aren't open to the idea that these scientists could be right.  And before someone says "Well, the climate change people aren't open to the idea that it's not happening" the problem is that most of the time we aren't arguing with skeptics who agree on scientific principles and who don't outright dismiss everything they say.  


If you're not willing to admit that there's a good chance humans are causing global warming, then you're not a skeptic.  You're a denier.  And you can't really say "Well it's not really settled" to back your claim, because you're assuming it's not settled on the right side yet (which is YOUR side according to you).  You've made the conclusion that your side is right, the other side is wrong.
