The arctic is warming at twice the rate as the rest of the world, which means the sea ice is shrinking at a rapid rate. The arctic has its lowest amount of sea ice since scientists began monitoring it by satellite in the 1970s. It begs the question, can't we just refreeze the ice? The answer might actually be, "yes."

A team of Indonesian designers want to produce iceberg-making submarines. The team, led by architect Faris Rajak Kotahatuhaha, plans on creating a submergible vessel, which sounds a little bit like an elaborate ice cube tray. The submarine sinks below the surface of the sea, filling up a cavity with seawater. The salt is removed, and the water is frozen using a "giant freezing machine." The result is 16-foot thick and 82-foot wide hexagonal icebergs, which are then released into the sea. Why the hexagon shape? It allows the icebergs to interlock with each other, forming larger masses of ice. Each iceberg would take a month to create. The idea was recently named runner-up in an international design competition for sustainable ideas.

Canadian biologist Catherine La Farge spends a lot of time poking around the edge of a glacier on Ellesmere Island in the far northern reaches of her country. As the ice recedes some dozen feet a year now, she has collected scores of samples of what has been locked there for the four hundred years since the Little Ice Age—ancient mosses—and she recently accomplished what seems like science fiction: she brought some of it back to life.

Video: Watch Our Planet's Ice Disappear

Watch this incredible video of the "recent" history of ice on our planet, from its long retreat after the Ice Age to the current rapid big melt.

A couple of engineers at the Zurich University of Applied Sciences created this visualization of shrinking glaciers, polar ice caps, and ice shelves, starting back 21,000 years ago (at the peak of the last Ice Age), and ending 1,000 years from now.
