Actually and maybe a little ironically, global warming is possibly going to extend the long term ability for the earth to sustain life. The effects in the short term will be huge, but oil is a result of life, so we know there was life when the carbon levels were super high. However life has a tendency to remove carbon from the carbon cycle and with the earths core gradually cooling with time that also causes less volcanic activity therefore less carbon being output from the cycle. So with the massive dump of carbon from us it will allow the cycle to run longer.
And too answer you question, i think it will be the sun going red giant that will ultimately end life. We may end ourselves and maybe even multicellular life long before that but killing all life is a damn tall order when you consider single celled life.

To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
