Only if it get just a little warmer. Photosynthesis is temperature dependent however and its maximum is at a modest 20 degree C, above 40 degree C its efficiency falls rapidly [1]. If it gets much warmer than that, and a run-away greenhouse effect would ensure that, only algae and some bacteria survive a while longer. Once the oceans are boiling, it's hard to imagine any life surviving though. There doesn't seem consensus on whether Earth could truly reach a runaway greenhouse state or would rather just settle at a higher temperature. In any case, only the ecological (and consequently economic) crises and refugees problem are the ones currently living people will be affected by, but that ought to be enough to take action.
