Antarctic ice shelf retreats happened before

...y warm current, Circumpolar Deep Water, is causing high melt rates on the underside of an ice shelf in Pine Island Bay*. The gradual removal of this ice shelf may be causing the glaciers inland to flow faster, which could lead to enhanced drainage of part of the West Antarctic Ice Sheet, and a consequent ...

Scientists Replicate Hepatitis C Virus in Laboratory
