Climate change will strongly influence human well-being through changes in food production, water availability, spread of infectious diseases, and frequency of heat waves.
This map shows the pattern of thermohaline circulation also known as "meridional overturning circulation". This collection of currents is responsible for the large-scale exchange of water masses in the ocean, including providing oxygen to the deep ocean. The entire circulation pattern takes ~2000 years.
