US to remove sensors used to study climate change impacts on Atlantic Ocean

Starting this month, the US will begin dismantling an extensive deep sea observation system used by scientists around the world to understand how climate change is impacting the Earth's oceans. While most of the 900 scientific instruments are positioned in the waters off US states, one particular array - in the waters south of Greenland - is crucial for studying the impact of climate change on the circulation of the Atlantic Ocean. The World's Host Carolyn Beeler heard from Rene van Westen, an oceanographer at Utrecht University in the Netherlands.
