The Arctic is warming at three to four times the global average. However, new research suggests the slowing of a key ocean current could reduce projected Arctic warming by up to 2 degrees Celsius by the end of the century.

A new study, led by planetary scientists at the University of Hawai‘i at Mānoa, revealed that methane gas may be trapped within the icy surface of Saturn's moon Titan, forming a distinct crust up to six miles thick, which warms the underlying ice shell and may also explain Titan's methane-rich atmosphere.
