It is obvious that global warming is already impacting clime, water regime, plant and animal life. So far, a new analysis published in the journal Nature is the most exhaustive one, gathering data on the effects of global warming around the world, from cannibalistic polar bears to melting glaciers and earlier-bloomin... |

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 ... |

The polar bear is indeed a more iconic animal than the narwhal and, on top of that, despite being classified as marine, we can see it mostly on land. This may explain why people have been focusing more on it than on other Arctic animals, when warning about the danger of extinction caused by global warming. With all t... |

The sea level rise is well understood in the current conditions of global warming. Glaciers and ice sheets are melting fast. But it seems that we are largely unaware of the dimension of the phenomenon, as a new research presented at the European Geosciences Union conference in Vienna, Austria, this week, shows that b... |

It is global warming at a smaller scale. When El Niño begins, the deserts of the Peruvian coasts are turned to lakes, but great floods, violent cyclones, severe droughts and harsh winters occur worldwide, triggering hunger, epidemics, huge wildfires, and damages on crops, goods and environment. The most affected zone... |

Global warming works extremely fast. The next huge chunk of ice which is going to split off Antarctica is now hanging on by a thin strip. First, researchers detected a huge iceberg, 25 mi by 1.5 mi (41 km by 2.5 km), which has broken away from the shelf. But the team at the British Antarctic Survey (BAS) found in fa... |

In the North Pole, the first major victim of the global warming seems to be the polar bear. In Antarctica, the victims could be the Adélie penguins. Their ice-made home is melting, and while the southernmost populations are thriving, most are quickly plummeting.These penguins need the winter sea ice as a platform for... |

Fridges do not stop messing with the planet. After CFC gases dumped in the last decades into the atmosphere that destroyed a lot of the ozone layer, now another fridge issue is increasing the expelled amount of greenhouse effect gases. Eliminating "beer fridges", old devices encountered in many North American and Aus... |

That's the clearest seawater, a crystal clearness increased by the white sand. A coral reef is like a sea rainforest. Corals are colonies made up of polyps, small animals with a maximum diameter of 2.5 cm (1 in). The soft polyp is linked to its neighbor through living tissue covered by mucus. During the day, the... |

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!... Tuvalu is already a flooded nation. Paradoxically (or n... |

Plastics may be toxic, but this one could clean the atmosphere of green house effect gases. A specially developed plastic imitating cell membrane can take carbon dioxide out of natural gas, lowering the quantities of this greenhouse gas dumped into the atmosphere. The new material could also extract natural gas from ... |

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.

The decline of the severe ice shelf coming with the global warming, a process that has been observed in the last years in Antarctica and Greenland, is more and more prominent in the North Pole area. In Aug. 13, 2005, the giant Ayles Ice Shelf, the size of Manhattan (16 x 5 km; 10 mi x 3 mi), has broken out free from ... |

A trip into the Siberian tundra will remind you now of a visit at a cow farm. Because of the scent. But what you smell is not cow dung, but mammoth one: this is the syrupy mud, resulted from the thawing of the permafrost. Just another symptom of global warming: the prehistoric dung lifted from suspended animation. An... |

This haunted the Europeans for long: a short sea route to China. This is how America was discovered. After that, since the 16th century, various expeditions tried to find a sea route above North America or Siberia to get to China, without the long and painful journey through the Suez or Panama channels (and before by... |

Yeah, it looks like we will have to explain to our grandchildren what a Polar bear used to be, when the time comes. Now it seems we have to start with our kids first. In 2007, summer melting of the Arctic sea ice is expected to set a record low by the end of September, as data for the 8th of August seem to indicate. ... |

This is a tricky gas: while protecting life on Earth, ozone can be at the same time a slayer. This gas is constantly forming in a natural way from the oxygen in the atmosphere, while on the ground-level ozone has been increasing due to chemicals emitted by the burning of fossil fuels. The upper atmosphere (stratosphe... |

Global warming and overfishing come with unpleasant surprises. Packs of aggressive and large squids have invaded waters off California's central coast, destroying local fish populations.

In the end, life is a struggle for resources. Food and water are essential, and their lack appears to have been the reason for many wars along the history.

Scientists put great hopes on the Ocean to ease the effects of dumping too much global warming producing carbon dioxide (CO2), by absorbing and storing it at great depths.
