    • REVIEW The Last Glacial Termination - Science

      J. M. Schaefer,2,3 A. E. Putnam1 A major puzzle of paleoclimatology is why, after a long interval of cooling climate, each late Quaternary ice age ended with a relatively short warming leg called a termination. We here offer a comprehensive hypothesis of how Earth emerged from the last global ice age. A prerequisite

And during that time, there were at least four major glacial advances in the northern hemisphere. But between the ice advances, the climate may not have been much different than it is today. Also, prior to the last advance, which ended about ...

      2018). Climate models suggest that this region will be the last to lose its perennial ice cover (Laliberté et al., 2016; Sou & Flato, 2009), thus providing an important refuge for ice‐dependent species (Folger, 2018; WWF, 2018). As such, knowledge of the climate of this so‐called Last Ice Area (LIA) as well as the

    • Global climate evolution during the last deglaciation

      During the interval of global warming from the end of the Last Glacial Maximum (LGM) approximately 19 ka to the early Holocene 11 ka, virtually every component of the climate system underwent large-scale change, sometimes at extraordinary rates, as the world emerged from the grips of the last ice age (Fig. 1).

      The last ice age ended about 12,000 years ago. The next cooling cycle would be expected to start about 30,000 years or more into the future. Many theories have been proposed to explain the causes of ice ages. Any credible theory must explain what caused the ice to build up, how and why the

What did Ice Age Ireland look like? During the cold stages of the Ice Age, Ireland was under a blanket of snow and ice for thousands of years.

      suggested that the last Glacial Period ended later than 15000 years ago, instead of 80000 years ago as required by Croll’s astronomical theory. By the end of the nineteenth century, the theory fell into disfavor. The attention of the scientific world was drawn back to the ice age problem with the publication in 1924 of Milankovitch’s theory.

      About 17,300 years ago the ice dam broke, releasing a torrent of water that flowed toward the Pacific Ocean at a rate of 10 tim es the combined flow of all the rivers of the world. During the last Ice Age, a finger of the continental ice sheet crept southward into the Idaho Panhandle, damming the Clark Fork River and creating Glacial Lake Missoula.
