According to a recently-published study, it would appear that the entire island of Greenland rose by as much as a quarter of an inch in 2010. This happened primarily because a lot of ice on its landmass melted away, easing the pressure on the landmass itself.
A similar phenomenon is currently being observed in Anta... |

The extent of ice sheets covering the Arctic was the second-lowest in recorded history, since satellite observations of the region began back in 1979. What this means is that the trend of declining summer ice cover is continuing unabated. In all fairness, authorities failed to take any type of measures to prevent the... |

For decades, climate scientists have believed that ice sheets and caps only grow as snow that accumulates on top gets pressed by other layers of snow, and turned into ice. But this view is now being disproved by a new study, which finds that ice can also form at the bottom of sheets and caps.This was discovered by ex... |
