Arctic voyage finds global warming impact on ice, animals

Technology
The email arrived in mid-June, seeking to explode any notion that global warming might turn our Arctic expedition into a summer cruise. "The most important piece of clothing to pack is good, sturdy and warm boots. There is going to be snow and ice on the deck of the icebreaker," it read. "Quality boots are key." The Associated Press was joining international researchers on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North. But once the ship entered the fabled Northwest Passage between the Atlantic and the Pacific, there would be nowhere to stop for supplies, no port to shelter in and no help for hundreds of miles if things went wrong. A change in the weather might cause the mercury to drop ...
Scientists find 91 volcanoes under Antarctic ice

Scientists find 91 volcanoes under Antarctic ice

Technology
The largest volcanic region on Earth has been found thousands of meters below the surface of the ice sheet covering Antarctica.A survey of the region of the West Antarctic Rift System has revealed 91 new volcanoes hidden within the ice.The new volcanoes are on top of the 47 whose peaks are above the ice and were already known about.The volcanoes range in height from 100m to a towering 3,850m tall.Geologists say the range has similarities to east Africa's volcanic ridge, which was previously thought to have the densest concentration of volcanoes in the world.Image:The survey was suggested by an undergraduate student at the University of EdinburghIt is unclear whether the Antarctic volcanoes are active, but previous studies have suggested that during warmer periods volcanic activity does occ...

Massive Perseid meteor shower thrills stargazers

Technology
Stargazers were given a treat on Saturday night and in the early hours of Sunday as the Perseid meteor shower dazzled the sky.Meteors are small fragments of interplanetary debris and dust that enter the Earth's atmosphere at such a high speed that they usually burn up, producing the shooting stream of light.The Perseid meteor shower, one of the best-known of the meteor showers, is active from mid July until 24 August but its peak was expected to be this weekend, particularly Saturday night and in the pre-dawn hours of Sunday.One of those who stayed up was Twitter user John-GM7PBB who lives on the Isle of Lewis in Scotland.He told Sky News that he had set his camera up at about 11pm on Saturday and was rewarded with two beautiful images of a meteor above the horizon.His window of opportunit...
Record-breaking summer for renewable power

Record-breaking summer for renewable power

Technology
Supplies of renewable energy, such as solar and wind power, in the UK have outstripped fossil fuels this summer.On 26 May, solar panels produced more than a quarter of all electricity needed in the country, with windy and bright conditions helping renewable energy generation to smash records.And for the first time on 7 June, wind, nuclear and solar were all generating more than gas and coal combined.The falling cost of wind and solar technology makes it increasingly attractive and energy firms have installed tens of thousands of solar panels in recent years.The home roof market has also boomed with an estimated 900,000 systems now online, despite generous government subsidies all but drying up in the last two years.Image:Wind and solar power are quickly growing in popularityDunsfold Aerodr...
Judge to rule on submarine owner detained over disappearance

Judge to rule on submarine owner detained over disappearance

Technology
A judge will decide Saturday if the owner of an amateur-built submarine should be held in custody during an investigation into whether he is responsible for the disappearance of a Swedish woman who had been onboard his submarine that sank off Denmark's east coast. Peter Madsen was arrested Friday on preliminary manslaughter charges after his 40-ton, nearly 18-meter-long (60-foot-long) UC3 Nautilus sank. He has denied responsibility for the fate of 30-year-old Kim Wall, saying she had disembarked earlier. The woman's boyfriend alerted authorities that the sub had not returned, prompting a major search involving two helicopters, three ships and several private boats. The Navy said that the sub had been spotted sailing but then sank shortly afterward. Kristian Isbak, who had responded to the...
