Well ok, but an encyclopedia entry is not authoritative when it comes to providing the complete evidence of climate change caused by humans.
Furthermore, you're nitpicking one word in that article and trying to work backwards to say that we can include there's not enough evidence. I would say look at summaries of the scientific papers, how often they're cited by other papers etc.
There is enough evidence, though ,and as I mentioned, there are no other factors that add up to causing climate change on the level that it's happened other than human produced CO2
