"In this case, the only thing you are doing is delaying how long it takes till your house burns down. Global warming will happen regardless of humans"
Firstly, you don't know if it's going to burn down. You wouldn't stand idly by, if your house caught fire, would you??????
Secondly, Global warming may happen regardless of humans, but this is not the case this time. The earlier it is countered, the more can be done.
Earth can handle quite a bit itself. More CO2 available to vegetation for instance, will actually encourage growth, - thereby tying down more CO2.
(CO2 is actually used as a sort of a "fertilizer" in greenhouse production)
However, that is futile, if there is not enough vegetation to make any use of the increase in CO2.
