In spite of looking like a giant stretch of ice in the Northern Pacific, Greenland fulfills a number of functions in the region, not the least important of them being the fact that it helps keep the North Pole cool. The way it manages to accomplish that is by being large and white, in the purest of senses. Light comi... |

Experts have always thought that lower atmospheric temperatures help keep glaciers frozen in ice sheets, or on mountaintops, but new measurements from a NASA satellite show that ice spreads play a crucial role in keeping temperatures low. Greenland is especially important in this scheme, as its ices reflect back a la... |

A new survey conducted by the American space agency's Ice, Cloud, and land Elevation Satellite (ICEsat) has revealed that more and more ice is falling off the Greenland and Antarctic sheets into the world's oceans, as glaciers get thinner on account of global warming. The formations increase their flow rate... |

There is no doubt in anyone's mind that we are currently in a warm Earth period. And we're not talking here about the climate change-type of warming, but of the planet's natural warming/cooling cycle. The current trend began some 11,700 years ago, and that is why Danish researchers looking into the his... |

Using historical meteorological data, other accounts and a natural climate “archive,” researchers investigating the evolution of the ice sheet between Greenland and the North European island archipelago of Svalbard have determined that the ice there is at its lowest in 800 years of tracked history. This p... |

In their travels around the world, to places no one had gone before, old-era naturalists were amazed to discover enormous plant species in the tropical regions, and in other exotic places, and they could not explain why this was happening. Now, researchers have managed to finally elaborate a theory that explains why ... |

Recent investigations have proven that large and seemingly unmovable glaciers can rapidly shrink, in just a few centuries. Researchers from the University at Buffalo came to this conclusion after they analyzed traces left behind by a large ancient glacier, which existed in the Canadian Arctic. They concluded that the... |

In some of the most remote areas of the world, finding a suitable nesting place can be a real problem. That's why some birds don't even bother going through all that hassle, and remain in the regions around which they grow up. They take care of their young in the same nests that their parents used to rear t... |

According to a new scientific study, conducted by experts at the US National Center for Atmospheric Research (NCAR), the coasts of the United States and Canada may actually be more in danger than previous models have predicted. The largest threat comes from the melting ice sheet of Greenland, which, if separated from... |

Researchers find themselves puzzled by an unexpected phenomenon, namely the accelerating melting process of ice sheets on both the Arctic and the Antarctic. The reason why the melt is unexpected is because it doesn't only happen along specific portions of the two shelves, as it has done until now, but also on va... |

According to a new research, published by British and American researchers in the journal Nature Geoscience, the melting of the Greenland ice sheet may be nothing more than a localized phenomenon, and the process through which the ice sheet disintegrates, threatening the lives and possessions of hundreds of millions ... |

New research, published recently in the journal Science, seems to point at the fact that saber tooths, mammoths, giant sloths and camels, as well as the Clovis culture, were driven into extinction by a 1,300 year-long cold spell, triggered by numerous comet impacts in 6 states across the northern US and several in so... |

Recent NASA observations of the world's ice spreads, via the GRACE satellite system, show that the ice in all the major reserves, including Greenland, Antarctica, Alaska, and the Himalayas, is melting at an ever increasing speed. According to official estimates, over the past 5 years, more than 2 trillion tons o... |

Researchers were able to finally identify the mechanisms through which cracks appear in the large ice shelves covering Antarctica and Greenland, a process known as calving. Understanding exactly how this happens is crucial, as the two regions stock most of the ice on Earth, whose melting could increase sea levels by ... |

A large portion of Greenland's ancient glaciers is currently melting, at a very high speed, say locals. The roaring of the cracks can be heard for tens of miles in all directions. The people near the blocks of ice, who see glaciers melting every summer, reported that the large icebergs that used to come off the ... |

There is a common belief, largely fueled by multiple studies related to climate change and global warming, that Greenland's glaciers are slipping towards the ocean at even faster rates than previously thought. A newly published paper however shows that for the last 17 years or so, Greenland's ice sheet has ... |

Polar bears are highly emblematic in signaling the impact of global warming. The narwhal is the species most vulnerable to global warming. Yet, not only Arctic marine mammals are affected by global warming: western Greenland's caribou experiences a mismatched migration caused by warming, that translates in less ... |

NASA confirms it: the surface temperature of Greenland's ice sheet is going up, fueled by warming air, causing a melt at the surface of and throughout the mass of the ice cap. A total melting of the Greenland ice would raise sea level by about 23 ft (7.8 m). This may not happen, but Greenland has been adding 2 m... |

If the ocean levels rose by 13 cm (5 in) only between 1940 and 1980, before the current speeding of the global warming, a phenomenon that prolonged the day on Earth by 0.001 second, you can imagine what happened in the last three decades and what will follow!...

Vikings named this land Greenland only for 'promotional' goals, as it was mostly a frozen land. Rapid thawing on the world's biggest island has started to improve conditions for agriculture, commercial fishing, mining and oil exploration. Arctic temperatures experience the most dramatic rise with the g... |

Today's Greenland is an icy polar desert; just on the southern coast, there is some tundra vegetation, with its giants represented by dwarf birch and willows that do not grow taller than 1-2 ft (0.3-0.6 m). The name "Greenland" was given by the first Viking explorers just to attract colonists to the area. Wood d... |

Sea levels have risen 10 cm (4 inch) from the beginning of the industrial era, when people started to dump huge amounts of carbon dioxide resulted from the burning of the fossil fuels into the atmosphere. But what has occurred till now is nothing compared to what is going to happen if only the Greenland's ice sh... |

Who discovered America? When Columbus returned from the Antilles in 1493, he was not the first European to have stepped on the New World. It seems that 500 years before, a group of blond Scandinavians had done it. It happened during the Viking era, when these sailors and warriors were roaming northern Africa, eastern... |
