Glaciation during the late Middle Pleistocene is widely recognized across continental northwest Europe, but its extent and palaeoenvironmental significance in the British Isles are disputed. Although glaciogenic sediments at Wolston, Warwickshire, in the English West Midlands, have been used to define the stratotype of the Wolstonian Stage, their age has been variably assigned between marine isotope stages (MIS) 12 and 6. Here we present sedimentological and stratigraphical observations from five sites across the English West Midlands whose chronology is constrained by new luminescence ages from glaciofluvial sediments, supplemented by cosmogenic 36 Cl exposure dating of erratic boulders. The ages suggest that between 199 ± 5 and 147 ± 2.5 ka the British Ice Sheet advanced into the English West Midlands as far south as Moreton-in-Marsh, Gloucestershire. This advance is assigned to the Moreton Stadial of the Late Wolstonian Substage. Dating of the glaciation to this substage allows co

EXPERTS at a North-East university had shed new light on the ice sheets responsible for rapid sea level rise in Earth s recent past, offering vital clues as to what lies ahead should climate change continue unabated. Geological records tell us that, at the end of the last ice age around 14,600 years ago, sea levels rose at ten times the current rate – rising 18 metre over 500 years. Until now, the scientific community has not been able to agree about which ice sheet was responsible for this rapid rise, with the massive Antarctic Ice Sheet being a likely suspect, but some evidence pointing towards ice sheets in the Northern Hemisphere.

LONDON, April 1 Ice sheet melting at the end of the last ice age may have caused sea levels to rise at 10 times the current rate, a study published today by a team led by scientists from Britain’s Durham University said.
Based on geological records, the researchers estimate that oceans worldwide rose 3.6 metres per century over a 500-year period some 14,600 years ago.
