Scientists Warn Future Sea Level Rise May Be Worse Than Current Projections

CNN reports that scientists have discovered that the , Antarctic ice sheet is melting , in a new, concerning way. According to a new study, current projections , may be significantly underestimating , future sea level rise.The ice sheet's "grounding line" is the point at which ice rises from the seabed and begins to float. Warm ocean water is seeping beneath this grounding line and causing accelerated melting which could push the process to a tipping point.
