 According to a team of U.S. researchers, the icebergs around Antarctica, far from being sterile ice cubes, are full of activity that may have an important role in combating climate change.
Small marine ecosystems that form around the ice blocks with melted water mixed with sea water, can serve to absorb carbon dioxide from the atmosphere and plunging into the ocean, since the algae absorb carbon -releasing oxygen through photosynthesis and then pass the food chain. They become a focal point for small fish, algae and even birds.
One of the main consequences of climate change has been the increase in temperature, which has led to multiply the appearance of icebergs in the southern waters, chunks of ice ranging from a few inches square that protrude from the surface to others as large as European countries.

 Spain lead for the first time a research project of the European Space Agency, developed by the CSIC and the Polytechnic University of Catalonia, from space to measure the salinity of sea and soil moisture, and improving knowledge on climate change .
The announcement of this project, called SMOS, has coincided with the launch of SMOS Barcelona Expert Centre, who will be dealing with process data from the mission and coordinate the scientific activity of the fifty participating Spanish.

 A research team in Antarctica has discovered traces of tundra, in the form of fossilized plants and insects, which shows that the continent was a warmer place several million years ago, reports the National Science Foundation.
14 million years ago, the region experienced a climate change “abrupt and dramatic” which resulted in a drop of 8 degrees Celsius in a relatively short time in geological terms, what caused the extinction of plants and insects in the tundra and Antarctica became what it is today.

The International Union for Conservation of Nature (IUCN) today introduced the latest Red List of Threatened SpeciesThat has not stopped growing since its first edition in 1997. According to the report, the plant species most at risk (70%), followed by freshwater fish (37%), invertebrate animals (35%), amphibians (30%), reptiles (28%), mammals known (21%) and birds (12%).
 Red List contained 12,151 plants, of which 8500 are threatened with extinction and 114 are presently in the category extinct or extinct in the wild. Native American Queen (Puya raimondii) Has been reassessed and is maintained in the endangered category. This plant, found in the Andes of Peru and Bolivia, produces seed only every 80 years before he died and it is possible that climate change is already undermining their ability to flourish.

Stuart Haszeldine, a researcher at the University of Edinburgh (UK) has shown that sandstone rock formations under the seabed are capable of storing up to 150,000 million tonnes of CO2. According to the scientist, is the only option for storing carbon and achieve a reduction of 2 ° C in combating climate change.
 “This is a massive storage capacity could amount to hundreds of years of carbon from power plants,” said Stuart Haszeldine, a study author and researcher at the University of Edinburgh (United Kingdom). For the British geologist, another advantage of the underwater storage is that “it is safer and faster than underground storage.
