New Zealand glaciers melted as European glaciers briefly expanded As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in the north, Antarctica was heating up. For the two decades since ice core records revealed simultaneous warming and cooling at opposite ends of the planet during this time period, scientists have looked for an explanation....

North Pacific circulation radically changed by past post-glacial warming Toward the end of the last ice age, a major reorganization took place in the current system of the North Pacific with far-reaching implications for climate, according to a new study published in the July 9, 2010, issue of Science by an international team of scientists from Japan, Hawaii, and Belgium. Earth's climate is regulated largely by the world ocean's density-driven circulation, which brings warm surface water to...

A chain of past natural events may hold lessons for the future Scientists still puzzle over how Earth emerged from its last ice age, an event that ushered in a warmer climate and the birth of human civilization. In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger, at least initially, was an orbital shift that caused more sunlight to fall across Earth's northern half. But how...

Researchers here are hopeful that the new core they drilled through an ice field on the Antarctic Peninsula will contain ice dating back into the last ice age.  If so, that record should give new insight into past global climate changes. The expedition in early winter to the Bruce Plateau, an ice field straddling a narrow ridge on the northernmost tongue of the southernmost continent, yielded a core that was 445.6 meters (1,462 feet) long, the longest yet recovered from that region of...

Researchers evaluate climate fluctuations from 115,000 years ago At the end of the last interglacial epoch, around 115,000 years ago, there were significant climate fluctuations. In Central and Eastern Europe, the slow transition from the Eemian Interglacial to the Weichselian Glacial was marked by a growing instability in vegetation trends with possibly at least two warming events. This is the finding of German and Russian climate researchers who have evaluated geochemical and pollen...

The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented. "At no time during the last 14 thousand years was there a period of climate warming and loss of ice as large and regionally synchronous as that we are now witnessing in the Antarctic Peninsula,"...

The 'Coastland Map' produced by scientists from Durham University and published in the Journal GSA Today, charts the post Ice-Age tilt of the UK and Ireland and current relative sea-level changes. According to the map, the sinking effect in the south could add between 10 and 33 per cent to the projected sea-level rises caused by global warming over the next century. * The projections are less than previous estimations for subsidence and could help local authorities to save money on sea and...

British scientists say they have created a model of the British and Irish ice sheets that shows they moved in unexpected ways. Durham University researchers said their model reveals for the first time how the glaciers reversed their flows and retreated back into upland regions from where they originated. During the last glacial maximum, around 21,500 years ago, the ice sheets built up on the high land of the Lake District, north Pennines and Scottish Southern Uplands, the researchers said. As...

The ice sheets that sculpted the landscape of northern Britain moved in unexpected ways and left distinctive egg-shaped features according to new research. Scientists from Durham University have deciphered the landforms and created a model of the British and Irish Ice Sheet (BIIS) which reveals for the first time how glaciers reversed their flows and retreated back into upland regions from where they originated. These ice sheet flow patterns created a unique 'overprinting' of British glacial...

A new international research effort on the Greenland ice sheet with the University of Colorado at Boulder as the lead U.S. institution set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future.The project, known as the North Greenland Eemian Ice Drilling, or NEEM, is being undertaken by 14 nations and is led by the University of Copenhagen. The...
