During the most recent ice ages of the Quaternary (the last 2.6 million years), continental ice sheets covered much of Canada, the northern United States, northern Europe, and extended into the Arctic Ocean, with the Antarctic Ice Sheets growing to the continental shelf break (Figure 1) (Clar...
A team of scientists led by researchers from Caltech report in this week's issue of the journal Nature that the rocks on which much of a theory on how the "Snowball Earth" ice age ended was based were formed millions of years after the ice age ended, and were formed at temperatures so...
In 1912 German meteorologistAlfred Wegener, impressed by the similarity of thegeographyof the Atlantic coastlines, explicitly presented the concept ofcontinental drift. Though plate tectonics is by no means synonymous with continental drift, the termencompassesthis idea and derives much of its impact fro...
Recent studies suggest that Antarctica has the potential to contribute up to ~15 m of sea-level rise over the next few centuries. The evolution of the Antarctic Ice Sheet is driven by a combination of climate forcing and non-climatic feedbacks. In thi
The total amount of ice is even more awesome if weestimate the water released upon the hypothetical melting of the world's glaciers. Se level would riseabout 60 meters. This would change the geography of the planet considerably. In contrast, shouldanother ice age occur, se level would drop ...
While differences in local geography may partly account for this contrast, the seasonal signal appears strongly developed in the rhythmite data, which is consistent with the findings of Section 2.1.5 that a significant seasonal cycle existed during the Elatina glaciation. The essentially noise-free ...
For example, overexpression of cardiac Gsα or β-adrenergic receptors in transgenic mice results in enhanced cardiac function in young animals, but with prolonged overstimulation of this pathway, cardiomyopathy develops in these mice as they age. Similarly, chronic sympathomimetic amine therapy ...
