Flip-flop end to last ice age
Article Abstract:
The astonishing report in 1993 that Greenland's climate twice shifted from glacial to interglacial conditions within a span of 3-5 years was discussed. The finding was based on ice-core measurements of annual ice-layer thickness over the past 15,000 years. It supports earlier hypotheses that the climate system of the Earth flips between several different modes. The more important issue, however, is whether the climate shifts are caused by external factors or by internal factors, which would include anthropogenic ones.

Near to the edge of an ice sheet
Article Abstract:
The high July solar-radiation levels at the time when the Laurentide ice sheet in northern North America existed resulted in uncommon climatic conditions that underwent significant changes over relatively short distances. A new study conducted by Levesque et al. that examined July temperature changes within a transect of five lakes located near a North American ice sheet revealed a remarkably sharp late-glacial climatic gradient.

Changes in Greenland ice sheet elevation attributed primarily to snow accumulation variability
Article Abstract:
Research is presented concerning the effect of climatic changes on the grounded ice sheets of southern Greenland between 1978 and 1988. The changes in elevation are found to be caused by variability in snow accumulation.
