An extreme form of solar storm, known as a solar proton event (SPE) struck our planet in 660 BCE. If an event of such magnitude were to happen today, it would likely wreak havoc on our technological infrastructure.
New science suggests Greenland may be approaching a dangerous tipping point, with implications for global sea-level rise.
The fate of one small Greenland town depends on which direction the winds blow. They're the only thing standing between the town of Innaarsuit and a 11-million-ton iceberg that floated dangerously close to shore.
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.
