Pretty much nothing. If climate change is, in fact, caused by human activity, we are well past the point of no return. So live your life as you would, enjoy the limited time you have, care for your loved ones, eat and drive whatever pleases you, and take in all the beauty and pleasure the world has to offer! If anything, reasonable people should fight inhumane and illiberal government efforts to control human activity. To the extent that anything can or should be done about climate change, simple and natural capitalist incentive should provide ample solutions.
