Satellite observations show that parts of the Antarctic ice sheet are currently thinning in response to a warming ocean. Of particular concern is the potential for ‘marine ice sheet instability’, where an initial retreat of ice margins into deepening valleys could lead to continued, unstable ice loss.

One of the lows, designated System 97B continued to linger along the southeastern Indian coast on November 17. As System 97B and another low pressure area dropped heavy rainfall, NASA and partners around the world gathered data using an array of satellites.
