Open seasonally, the Going-to-the-Sun Road in Montana’s Glacier Park is 50 miles of big mountains, plunging waterfalls and massive glaciers. For 33 miles of the drive, there isn't a single service station or restaurant to be found. However, travelers may meet a few mountain goats and b...
aWhen a volcanic eruption in Iceland sends a glacier hurtling toward North America, a family struggles to escape the onslaught of the coming ice age.…… 当火山爆发在冰岛送投出往北美洲的冰川,逃脱以后的冰河时期的猛击的家庭奋斗...[translate]...
About one million years ago,the Ice Age began.The Ice Age was a long period of time in which four great glaciers(冰川) pushed southward to cover almost all the upper half of North America,and then melted away.Each glacier was a thick sheet of ice and snow that spread out from a cente...
a第四纪冰川期间,罗霄山脉和南岭以南的地区成为喜温生物的避难所,一些北方的昆虫在冰川的驱赶下向南迁移至罗霄山脉及南岭以南。冰川期结束后,部分生物又向北方迁移,而另一部分则留在罗霄山脉以南的地区,与原生于罗霄山脉以南的昆虫一同形成了现代昆虫区系。作为罗霄山脉的一部分,井冈山昆虫区系与南部其他地区的昆虫...
Along with the present-day glacial outlines, the map also includes a reconstruction of the extent of the glaciers during the Little Ice Age, inferred from morphological features such as LIA and post-LIA moraine ridges as well as the aid of historical archive data. Some basic glacier ...

Secular warming in the late 19th century to present corresponds with the only multi-decadal intervals of negative mass balance in all glacier reconstructions. This suggests that contemporary retreat in western North America is unique with respect to the last several centuries and that regional patterns...
“In the case of the North Atlantic prior to the Little Ice Age, this loss of resilience made the system vulnerable to an abrupt switch, potentially heralding the transition to Little Ice Age conditions,” said Dr. Paul Halloran, who co-led the research. ...
icebergs grounded at the sea bottom. They likely came from a nearby glacier, where other newly calved icebergs, covered with gravel from landslides, were ready to float off. This was not the first such disappearing act in the high Arctic, or the first need to erase land from the map. Nea...
The Victorian conceit of the polar regions as a vast empty wilderness, and the preserve of white males battling against the elements, was far from the only polar vision. Michael Bravo shows an alternative set of pictures, of a habitable Arctic criss-crossed by densely connected networks of Inui...
