Thickest parts of Arctic ice melting faster

A new study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean’s floating ice cap.

What if we could cheaply and efficiently detect a potent new energy source, while also monitoring for environmental safety? Physicists are using the symphony of sound produced in the ocean to do just that.

Rising sea levels are likely to change Southern California beaches in the coming century, but not in ways you might expect. While some beaches may shrink or possibly disappear, others are poised to remain relatively large — leaving an uneven distribution of economic gains and losses for coastal beach towns, according to a new study.
