Scientists shed light on human causes of North Atlantic’s ‘cold blob’

Have you ever looked at a map of the North Atlantic and wondered why there is an area in the North Atlantic Ocean that is getting cooler instead of warmer? Well, you are not alone. Scientists have been trying to understand this area for years. In the past it has been attributed to a slow-down in the meridional circulation of ocean water from the equator to the poles. But now, based on new climate modeling, the scientists know that is more complex than originally thought, and is also tied to changes in cloud cover and changes to the circulation in the Arctic, which add to the puzzle.
