As oceans suffocate, dead zones grow


A new analysis by the Smithsonian Environmental Research Center shows that oceans are suffocating as the number of dead zones is dramatically increasing.

Greenland's Sermilik fjord is choked with huge icebergs from one of the island's biggest glaciers. But climate researchers working in the fjord and on the Helheim glacier are looking for tiny clues in hopes of getting a better handle on how cliamte change

Looking small for big answers in Greenland


Scientists working in Greenland are looking for tiny clues to help fill in the big picture about the fate of the island’s giant ice pack. They’re using cutting edge technology to track minute changes that could help predict what a warmer future might hold for Greenland and the rest of the world.

Dark rock above the Helheim glacier in southeastern Greenland marks its former level, before a sudden and dramatic retreat of hit many Greenland glaciers a decade ago. Scientists working on the Helheim and the fjord it drains into are looking for clues to

In Greenland, a climate change mystery with clues written in water and stone


About a decade ago, several of Greenland’s biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island’s rapidly-melting ice sheet.

A rare colossal squid was dissected in New Zealand — and you can watch it on YouTube


Last summer in the southern hemisphere, a fishing vessel in the Antarctic Ocean pulled up a rare creature — a 770-pound colossal squid. Only one other such animal had been pulled up intact before, surprisingly, by the same vessel. It is thought that the giant marine beast might be the origin of legends of undersea monsters. Scientists in New Zealand froze it to preserve it and just defrosted and dissected it.
