trepidation #2
南極地方の巨大な氷山が解け始めていることが調査で明らかになりました。観測された氷山は，世界で10番目に大きな氷山です。
記事の中で気になった単語は"trepidation"です。『Wisdom英和辞典第三版』（三省堂）を調べると「恐怖, おののき; ろうばい」などという意味がありました。Oxford Dictionaries.comには"A feeling of fear or anxiety about something that may happen"と定義されております。氷塊の原因は地球温暖化にあると専門家は主張しております。(Ume)
Huge Antarctic iceberg poised to break away
A long-running rift in the Larson C ice shelf grew suddenly in December and now just 20km of ice is keeping the 5,000 sq km piece from floating away.
Larsen C is the most northern major ice shelf in Antarctica.
Researchers based in Swansea say the loss of a piece a quarter of the size of Wales will leave the whole shelf vulnerable to future break-up.
Larsen C is about 350m thick and floats on the seas at the edge of West Antarctica, holding back the flow of glaciers that feed into it.
Researchers have been tracking the rift in Larsen C for many years, watching it with some trepidation after the collapse of Larsen A ice shelf in 1995 and the sudden break-up of the Larsen B shelf in 2002.
