The Amazon river is the largest river system in the world, discharging huge volumes of fresh water into the ocean. Scientists from the Center for Atmospheric and Oceanic sciences have explored what would be the effect of the reduction in the Amazon river’s runoff into the ocean. The scientists demonstrate the wide ranging climatic changes that can occur if the river discharges lesser water into the Atlantic ocean.
