Evidence From Ice Age That Climate Change Can Have A Rapid Effect On Ocean Circulation

10-09-2006 · ScienceDaily

Sudden shifts in temperature over Greenland and tropical rainfall patterns during the last ice age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. The results provide further evidence that climate change can have a direct and rapid impact on ocean circulation and chemistry.

Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean, according to research published Oct. 5, 2006, in the journal Nature.

Climate swings have brought great CO2 pulses up from the deep sea
05-11-2007 · EurekAlert!
A study released provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere.

Melting of the Greenland ice cap may have consequences for climatic change
05-07-2007 · EurekAlert!
At the last ice age, before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which covered the British Isles had already begun to affect the circulation of the ocean currents. Based on this observation, scientists consider that the acceleration of the melting of the Greenland ice cap could play an important role in the development of climate change.

Research finds evidence tropical cyclones have climate-control role
05-31-2007 · EurekAlert!
Purdue University researchers have found evidence that tropical cyclones and hurricanes play an important role in the ocean circulation patterns that transport heat and maintain the climate of North America and Europe. These findings suggest that there is an additional factor to be included in climate models that may change predictions of future climate scenarios.

Peruvian glacier may vanish in 5 years
02-15-2007 · EurekAlert!
When glaciologist Lonnie Thompson returns to Peru's Qori Kalis glacier early this summer, he expects to find that half of the ice he saw during his visit there last year has vanished. What troubles him the most is his recent observations that suggest that the entire glacier may likely be gone within the next five years, providing possibly the clearest evidence so far of global climate change.

First direct evidence that human activity is linked to Antarctic Ice Shelf collapse
10-16-2006 · EurekAlert!
The first direct evidence linking human activity to the collapse of Antarctic ice shelves is published this week in the Journal of Climate. Scientists from the British Antarctic Survey, the Center for Polar Observation and Modeling, University College London and the Katholieke Universiteit Leuven, reveal that stronger westerly winds in the northern Antarctic Peninsula, driven principally by human-induced climate change, are responsible for the marked regional summer warming that led to the retreat and collapse of the northern Larsen Ice Shelf.

Tundra disappearing at rapid rate
03-05-2007 · EurekAlert!
Forests of spruce trees and shrubs in parts of northern Canada are taking over what were once tundra landscapes -- forcing out the species that lived there. This shift can happen at a much faster speed than scientists originally thought, according to a new University of Alberta study that adds to the growing body of evidence on the effects of climate change.

Climate change affects Southern Ocean carbon sink
05-17-2007 · EurekAlert!
The first evidence that recent climate change has weakened one the Earth's natural carbon 'sinks' is published this week in the journal Science. A four-year study by scientists from the University of East Anglia, British Antarctic Survey and the Max-Planck Institute for Biogeochemistry reveals that an increase in winds over the Southern Ocean, caused by greenhouse gases and ozone depletion, has led to a release of stored CO2 into the atmosphere and is preventing further absorption of the greenhouse gas.

Immediate action needed to save corals from climate change
12-13-2007 · EurekAlert!
The journal Science has published a paper today that is the most comprehensive review to date of the effects rising ocean temperatures are having on the world’s coral reefs. "The Carbon Crisis: Coral Reefs under Rapid Climate Change and Ocean Acidification," co-authored by 17 marine scientists from seven different countries, reveals that most coral reefs will not survive the drastic increases in global temperatures and atmospheric CO2 unless governments act immediately to combat current trends.

Ice Ages and rivers may have affected gorilla diversification
12-10-2007 · EurekAlert!
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans.The collaborative School of Biosciences study shows that the genetic composition of gorilla populations varies across different parts of their current geographic range and that this variation may be tied to Ice Age climate change and river barriers.
