December 20, 2005 Polar bears get all the attention when it comes to species threatened by global warming. But little black ice worms, which live on glaciers, are just as much in danger. NASA officials say ice worms offer clues as to how life can exist in extreme environments, maybe unlocking mysteries about possible life on other planets or chilly moons.

Some believe global warming may be affecting this heat engine, but others are skeptical, given how complex the ocean can be. The debate is part of a larger effort by scientists to detect climate changes with sketchy data.
