A quick fix for global warming - BBC Magazine - [You must be registered and logged in to see this link.] - By Chris Bowlby BBC News - It's the stuff of science fiction, but could mirrors in space or sea water sprayed in the air be shortcuts to halt global warming? - "It's Dr Strangelove. But it's the kind of Dr Strangelove you could see governments really using." - That's how one expert describes geo-engineering - the idea that we can use a kind of technical quick fix to cool the planet if global warming accelerates. Plans for geo-engineering can sound bizarre. - That plan was inspired by watching what happened after the eruption of the Mount Pinatubo volcano in the Philippines in 1991. - 31 July 2008.

Airline in first biofuel flight - [You must be registered and logged in to see this link.] - BBC News Science/Technology - The first flight by a commercial airline to be powered partly by biofuel is to take off from London. - Billed as a green fuel breakthrough, the Virgin Atlantic flight to Amsterdam will not have any passengers on board. - Earlier this month, Airbus used the world's largest passenger jet, the A380 to flight test another alternative fuel - a synthetic mix of gas-to-liquid. - 24 February 2008.
Antarctic glaciers surge to ocean - [You must be registered and logged in to see this link.] - BBC Science/Technology - By Martin Redfern Rothera Research Station, Antarctica - UK scientists working in Antarctica have found some of the clearest evidence yet of instabilities in the ice of part of West Antarctica. If the trend continues, they say, it could lead to a significant rise in global sea level. - 24 February 2008.
Antarctic shelf 'hangs by thread' - [You must be registered and logged in to see this link.] - BBC Science/Technology News - By Helen Briggs Science reporter, BBC News - A chunk of ice the size of the Isle of Man has started to break away from Antarctica in what scientists say is further evidence of a warming climate. - Satellite images suggest that part of the ice shelf is disintegrating, and will soon crumble away. - 25 March 2008.
Arctic ice 'is at tipping point' - [You must be registered and logged in to see this link.] - By Richard Black Environment correspondent, BBC News website - Arctic sea ice has shrunk to the second smallest extent since satellite records began, US scientists have revealed. - The National Snow and Ice Data Center (NSIDC) says that the ice-covered area has fallen below its 2005 level, which was the second lowest on record. - Melting has occurred earlier in the year than usual, meaning that the iced area could become even smaller than last September, the lowest recorded. - Researchers say the Arctic is now at a climatic "tipping point". - 28 August 2008.
Arctic losing long-term ice cover - [You must be registered and logged in to see this link.] - By Richard Black Environment correspondent, BBC News website - The Arctic is losing its old, thick ice faster than in previous years, according to satellite data. - The loss has continued since the end of the Arctic summer, despite cold weather across the northern hemisphere. - 18 March 2008.
Arctic sea ice melt 'even faster' - [You must be registered and logged in to see this link.] - BBC - By Richard Black Environment correspondent, BBC News website - Arctic sea ice is melting even faster than last year, despite a cold winter. - Data from the US National Snow and Ice Data Center (NSIDC) shows that the year began with ice covering a larger area than at the beginning of 2007. - But now it is down to levels seen last June, at the beginning of a summer that broke records for sea ice loss. - Scientists on the project say that much of the ice is so thin that it melts easily, and the Arctic may be ice-free in summer within five to 10 years. - 18 June 2008.
