A massive Antarctic ice shelf is breaking up and pieces are expected to float away as icebergs over the course of the next few weeks. Scientists estimate the Wilkins Ice Shelf, which was originally about the size of Northern Ireland, had been in place for several hundred years. But satellite images taken over the past week show it has begun collapsing into the ocean as more than half a dozen similar Antarctic ice shelves have already done, said an article posted Tuesday by the European Space Agency on its website.
For the fifth year running a massive concentration of Argentine environmentalists and picketers marched Sunday across an international bridge linking with Uruguay to protest against a pulp mill built on the Uruguayan side and which has been at the heart of a bilateral political and diplomatic dispute between the neighbouring countries.
Water levels in some of the world's most important rivers have declined significantly over the past 50 years, US researchers say. They say the reduced flows are linked to climate change and will have a major impact as the human population grows.
Forests' role as massive carbon sinks is at risk of being lost entirely, top forestry scientists have warned. The International Union of Forest Research Organizations (IUFRO) says forests are under increasing degrees of stress as a result of climate change.
Polar bears, the poster children for Arctic climate change, are getting competition for the title of climate change casualty from the opposite side of the globe. Antarctica’s emperor penguins may face an equally dire fate. Like polar bears, these birds depend on sea ice for breeding and feeding habitat. Also like polar bears, emperor penguins seem unlikely to adapt to the rapid rate of sea ice extent change, according to a National Academy of Science study released by the National Centre for Atmospheric Research.
A report by a Brazilian official organization published on Saturday in the daily O Globo criticized the lack of security at Brazil’s nuclear installations, which range from electricity-generating plants to hospital equipment.
FALKLANDS, Argentine, and Chilean cruise ship tourism is likely to be negatively impacted as a result of a ban on the use and carriage of Heavy Gas Oil (HGO) in Antarctic waters by the International Maritime Organisation (IMO).
United States Secretary of State Hillary Clinton called on Monday for tighter regulation of Antarctic tourism as delegates from 47 countries began a review conference of the now 50-year-old Antarctic Treaty.
Chilean-based LAN Airlines recently announced it will reduce the consumption of combustible fuel by 16.6 million gallons each year with the installation of “winglets” on all 37 of its Boeing 767-300 aircrafts as part of the airline’s endeavor to improve flight efficiency.
An ice bridge which held a vast Antarctic ice shelf in place shattered at the weekend and could herald a wider collapse linked to global warming, a leading scientist has warned. It's amazing how the ice has ruptured. Two days ago it was intact, said David Vaughan, a glaciologist with the British Antarctic Survey.
