Not "it's happening" - don't tell me the polar ice caps are melting, they've been melting for 12,000 years, they used to extend to New Jersey.
Not "only an idiot would doubt it now" - I read the Emperor's New Clothes too.
Not "everybody knows" - "everybody knows" a lot of things that aren't true.
Not "the scientists say" - a lot of smart people suspect it, but that's not proof and it's NOT all of them.
Not "CO2 traps heat and we started pumping billions of tons into the atmosphere 80 years before this warm period began, ipso facto......." There have been countless similar warm periods when CO2 levels were lower, there are other gases with far greater heat-trapping properties that aren't contributed by man, and the increase in atmospheric CO2 concentration in relation to the atmosphere is 90 parts per million, or 1/11,000th, over 200 years.
The closest thing to "proof" that I've seen is the cooling stratosphere, but that started happening less than 20 years ago.
