Final answer:
Thermohaline circulation is the ocean circulation driven by temperature and salinity differences. Global climate change can impact it by altering temperature and salinity patterns.
Step-by-step explanation:
Thermohaline circulation refers to the large-scale ocean circulation driven by differences in temperature and salinity. It plays a crucial role in distributing heat and nutrients around the globe. Global climate change can impact thermohaline circulation by altering the temperature and salinity patterns in the ocean. Melting of glaciers and polar ice caps can increase freshwater input into the ocean, reducing the salinity and disrupting the circulation patterns.
