20120719 BBC_Iceberg breaks off from Greenland's Petermann Glacier
The Petermann Glacier in northern Greenland has calved an iceberg twice the size of Manhattan, scientists say.
Images from a Nasa satellite show the island breaking off a tongue of ice that extends at the end of the glacier.
In 2010 an ice island measuring 250 square km (100 square miles) broke off the same glacier.
Glaciers do calve icebergs naturally, but the extent of the changes to the Petermann Glacier in recent years has taken many experts by surprise.
However, the calving is not expected have an impact on sea levels as the ice was already floating.
Icebergs from the Petermann Glacier sometimes reach the coast off Newfoundland in Canada, posing a danger to shipping and navigation, according to the Canadian Ice Service.
Scientists have also raised concerns in recent years about the Greenland ice shelf, saying that it is thinning extensively amid warm temperatures.

20120611 Apple Daily 林鄭:東涌發展橋頭經濟
【本報訊】發展局局長林鄭月娥(圖)昨日出席東涌地區團體舉辦的模型展覽時表示,東涌未來可進一步發展,將由現時約13萬人口,增加至約23萬人的市鎮;加上十大基建中如港珠澳大橋等都與東涌連接,認為該區有潛力發展「橋頭經濟」效應。
她指出,東涌有15幅土地已納入分區計劃大綱圖,其中3幅土地可興建住宅單位,包括一幅位於56區的土地正計劃興建公屋,但計劃被同區私樓居民反對暫時擱置。有地區團體建議,政府可開發東涌大約150公頃的土地,提供約2.4萬個公私營住宅單位及休憩場所,並興建由東涌到迪欣湖的單車徑。

20120609 日擬重開核電廠 民眾抗議
日本311大地震引發的核災難,至今仍未完全解決,首相野田佳彥昨日(周五)召開記者會游說國民,為了保障就業和人民的生活,必須重開其中兩個已暫停運作的核反應堆,結果觸發大批民眾抗議。
福島核災爆發後,日本上月初暫停了全國50個核反應堆運作,卻引發電力不足問題。野田指出,隨着夏季來臨,電力需求增加,其中西部地區預期會缺電15%,缺電問題很嚴重,刻不容緩,必須重新啟動部份核反應堆。
他指西部福井縣大飯核電廠第三和第四號反應堆已準備好恢復運作,強調當局已採取充足安全措施,確保再發生像311那麼嚴重的大地震和海嘯,反應堆都不會洩漏輻射。
但大批反核人士在首相府外抗議,拉起寫有「堅決反對大飯核電廠重開」、「打倒野田政權」等抗議標語。

20120520 BBC_Arctic melt releasing ancient methane
Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere.
The methane has been trapped by ice, but is able to escape as the ice melts.
Writing in the journal Nature Geoscience, the researchers say this ancient gas could have a significant impact on climate change.
Methane is the second most important greenhouse gas after CO2 and levels are rising after a few years of stability.
There are many sources of the gas around the world, some natural and some man-made, such as landfill waste disposal sites and farm animals.
"If this relationship holds true for other regions where sedimentary basins are at present capped by permafrost, glaciers and ice sheets, such as northern West Siberia, rich in natural gas and partially underlain by thin permafrost predicted to degrade substantially by 2100, a very strong increase in methane carbon cycling will result, with potential implications for climate warming feedbacks."
"The Arctic is the fastest warming region on the planet, and has many methane sources that will increase as the temperature rises," commented Prof Euan Nisbet from Royal Holloway, University of London, who is also involved in Arctic methane research.
"This is yet another serious concern: the warming will feed the warming."
How serious and how immediate a threat this feedback mechanism presents is a controversial area, with some scientists believing that the impacts will not be seen for many decades, and others pointing out the possibility of a rapid release that could swiftly accelerate global warming.
Many of the sites were bubbling methane that has been stored for millennia
Atmospheric methane concentration is rising again after a plateau of a few years
