The ebb and flow of the ocean tides, generally thought to be one of the most predictable forces on Earth, are actually quite variable over long time periods, in ways that have not been adequately accounted for in most evaluations of prehistoric sea level changes.

Climate researchers at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association expand a prevalent theory regarding the development of ice ages. In the current issue of the journal Nature, three physicists from AWI's working group "Dynamics of the Palaeoclimate" present new calculations on the connection between natural insulation and long-term changes in global climate activity.

Southampton researchers have estimated that sea-level rose by an average of about 1 meter per century at the end of the last Ice Age, interrupted by rapid "jumps" during which it rose by up to 2.5 meters per century. The findings, published in Global and Planetary Change, will help unravel the responses of ocean circulation and climate to large inputs of ice-sheet meltwater to the world ocean.

 | A new study in Nature finds that in addition to Antarctica, New Zealand was warming at the end of the last ice age, indicating that the deep freeze up north, called the Younger Dryas for the white flower that grows near glaciers, bypassed much of the southern hemisphere. ...> Full Article |
