How stable is deep ocean circulation in warmer climate? Altered circulation might have cooled northern areas of North America and Europe

  • Now, a Rutgers coauthored study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.
  • Melting of the polar ice sheet in the Arctic region would result in more fresh water entering the ocean and disrupting that circulation pattern, potentially causing cooling in northern areas of Europe and North America.
  • Increased freshwater entering the Arctic region due to melting of the polar ice sheet in a warmer world may have disrupted circulation.
