Some scientists are saying that a record-setting area of cold water in the North Atlantic, revealed by recent National Oceanic and Atmospheric Administration (NOAA) data, could be a sign that climate change is causing the ocean current to weaken.
This trend could have dramatic consequences, including the alteration of temperatures on the European and North American continents.
Washington Post reporter Chris Mooney highlighted the thesis on Thursday, pointing out a cold blob in the ocean south of Greenland and Iceland. While NOAA’s findings that 2015 has so far seen the hottest eight month stretch in recorded history were widely publicized, the North Atlantic cold spot is lesser known. It is seen below in the dark hue denoting “record coldest” temperatures.
Deke Arndt, chief of the climate monitoring branch at NOAA’s National Centers for Environmental Information, confirmed to Mooney that the cold temperatures are not a fluke, stating: “For the grid boxes in darkest blue, they had their coldest Jan-Aug on record, and in order for a grid box to be ‘eligible’ for that map, it needs at least 80 years of Jan-Aug values on the record.”
Prior studies have predicted such a trend.… Read the rest
