Glacial decline冰川下降 and the gradual循序漸進 loss of polar極地 ice caps has been a worrying trend over recent decades, but scientists have been aware察覺 of an apparently似乎, 表面上 curious好奇的 anomaly異常 with the Karakoram, which contains包含 some of the world's biggest mountains including the second highest, K2. It has about 20,000 square kilometres of glaciers, accounting for three percent of the total area of ice outside the Antarctic and Greenland ice sheets.冰原
Now a team of French scientists has carried out a detailed survey over a large area of the range using sophisticated複雜 remote-sensing遙控 measurements測量. Writing in the scientific journal, Nature, they say they found that in the first years of this century the Karakoram's glaciers had actually expanded擴大 by a small amount, while in the neighbouring Himalayas they'd been shrinking縮.
It's unclear why this is happening, but it seems that by a quirk怪僻 in the weather pattern that's not fully understood, less heat is being delivered to the Karakoram and the mountains are receiving heavier falls of snow.
