# Polar Oceans and World Climate

Understand how polar oceans connect to the global climate system — cold, dense polar water sinks and drives thermohaline circulation (a global conveyor belt of ocean currents), sea ice reflects sunlight back to space (the albedo effect) helping regulate Earth's temperature, and the Southern Ocean around Antarctica is one of the most productive marine ecosystems on Earth due to upwelling nutrients
