A massive iceberg has broken off from a glacier in Greenland and has started drifting south into shipping lanes and waters occupied by oil rigs.

A University of Delaware researcher reports that an 'ice island' four times the size of Manhattan has calved from Greenland's Petermann Glacier.

A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth's atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.
