A team of NYU scientists has captured on video a four-mile iceberg breaking away from a glacier in eastern Greenland. This phenomenon, known as "calving", is a force behind the rise of global sea water levels.
The Dark Zone is a stripe of fast-melting ice towards the south-west of the ice sheet. This speedy melting is actually bad news for the planet, especially the areas bound to be affected by a sea level rise.
Researchers working in Greenland have found traces of microbial life in our planet's most ancient rocks. The discovery pushes back the oldest evidence of life on Earth by about 220 million years, showing just how habitable our planet was during its earliest stages.
