In a development that could have serious implications on our planet's future, scientists announce that the multi-year ice that once adorned the North Pole is all but gone at this point. In its stead, seasonal ice, that freezes and then melts every year, seems to be the primary form of frozen water at the locatio... |

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... |

In spite of the fact that hovercraft are usually used for navigating swamps and shallow waters, a few modifications are, apparently, enough to turn them into potent scientific tools. Researchers Yngve Kristofferson and John Hall are planning to use a modified Griffon Hovercraft 2000TD to analyze a patch of Arctic sea... |

The American space agency NASA started measuring the extent of Arctic ices in 1979, via its satellite program. Since then, it has conducted constant investigations of the North Pole, and has drawn maps of ice extents during every minimum and maximum extent of the ice sheets. Measurements for this year indicate that t... |

Winter was until recently the traditional season when up to 90 percent of bird species in the Arctic migrated South, to warmer skies. But that seems to no longer apply today. An investigation by the US Geological Service (USGS) has recently determined that as much as 30 percent of species would now rather spend their... |

According to a newly released report from the World Wide Fund For Nature (WWF) released today, September 2nd, it would appear that the current warming trend recorded in the Arctic could have massive repercussions on our planet. The study shows that as much as one quarter of the globe's population could be floode... |

When they compared polar bear skulls that were harvested in the early 20th century with modern-day ones, researchers discovered that the older remains were significantly larger in size than the newer specimens. Experts believe that, at this point, the large mammals are being forced to reduce their size on account of ... |

In addition to carbon dioxide, the main gas held responsible for global warming, methane, is one of the most potent agents that can bring about climate change. Efforts of reducing emissions exist, but they are insufficient. To make matters worse, it has been recently confirmed that the gas escapes its Arctic sea-bed ... |

More than 8,000 years ago, in the Holocene Period, the Ross Sea Embayment was covered in a thick layer of ice, which prevented a too large diversity of species from gaining a strong foothold in the region. As the ice progressively retreated, elephant seals (Mirounga leonina) adopted the emergent habitat and spread ar... |

For the first time in recorded history, thin seasonal ice has replaced ancient ice as the dominant form of frozen water around the North Pole, a new survey by NASA shows.

For quite some time now, researchers have known that the vast amounts of carbon dioxide that are stored in the Arctic permafrost (frozen soils, river deltas and other sediments) will in the future play a significant part in the warming of the planet, but they never had a clear idea of just what extent this influence ... |

Despite the fact that the Arctic regions have passed through numerous changes over the millennia, one thing has remained the same – the fact that they are left in darkness for six months each year.

According to geological estimates, between 30 and 35 percent of the world's undiscovered oil deposits are found in the Arctic, alongside 13 percent of the globe's natural gas reserves.

More than 3.6 million years ago, a massive meteorite struck the Siberian plains, creating an 11-mile-wide crater. Over the millennia, water flowed into the crater and thus Lake El'gygytgyn (or Lake E) was formed. Now, all those years later, scientists from the United States, Germany, the Russian Federation and A... |

According to a recent study provided by the US National Aeronautics and Space Administration, the warming that has been recorded over the Arctic since 1976 may be due to an increase in the amount of particulate matter, known as aerosols, in the atmosphere. These aerosols can come from a variety of sources, both natur... |

Among the most important sources of nitrous oxide (N2O) today, forests and intensely-managed farmlands take the top.
