What vital global function is performed by the high specific heat capacity of water?

Answer

It absorbs enormous heat energy without drastic temperature change, acting as a global thermostat.

Water's high specific heat capacity allows large bodies of water to absorb substantial heat energy while moderating temperature fluctuations across the planet, which is necessary as many biological processes are temperature sensitive.
