Age is more than a number -- In barn owls, it reveals how susceptible one is to climate change
01-10-2007 · EurekAlert!Fluctuations in weather and the environment affect survival and reproduction of animals. But are all individuals within a population equally susceptible? Theory on the evolution in age-structured populations suggests not -- those life stages that are more important for overall fitness should be less susceptible to environmental variation than other life stages.

- New research shows climate change triggers wars and population decline
11-21-2007 · EurekAlert!
Climate change may be one of the most significant threats facing humankind. A new study shows that long-term climate change may ultimately lead to wars and population decline. The study, published Nov. 19 in the early edition of the journal Proceedings of the National Academy of Sciences, revealed that as temperatures decreased centuries ago during a period called the Little Ice Age, the number of wars increased, famine occurred and the population declined.

- Study shows largest North America climate change in 65 million years
02-07-2007 · EurekAlert!
The largest climate change in central North America since the age of the dinosaurs 65 million years ago, a temperature drop of nearly 15 degrees Fahrenheit, is documented within the fossilized teeth of horses and other plant-eating mammals, a new study reveals.

- Radar reveals view of land beneath polar ice
12-11-2006 · EurekAlert!
In the first test of a new radar instrument, scientists have seen through more than a mile of Greenland ice to reveal an image of land that has been hidden for millions of years. Ohio State University scientists and their colleagues will use what they learn from the instrument, dubbed GISMO (for Global Ice Sheet Mapping Orbiter), to determine how global climate change will affect the ice.

- Chemistry of volcanic fallout reveals secrets of past eruptions
01-04-2007 · EurekAlert!
A team of American and French scientists has developed a method to determine the influence of past volcanic eruptions on climate and the chemistry of the upper atmosphere, and significantly reduce uncertainty in models of future climate change.

- 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.

- Scientists reveal first-ever global map of total human effects on oceans
02-14-2008 · EurekAlert!
More than 40 percent of the world's oceans are heavily affected by human activities, and few if any areas remain untouched, according to the first global-scale study of human influence on marine ecosystems. By overlaying maps of 17 different activities such as fishing, climate change, and pollution, the researchers have produced a composite map of the toll that humans have exacted on the seas.

- Researchers Link Ice Age Climate-change Records To Ocean Salinity
10-07-2006 · ScienceDaily
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.

- 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.

- 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.
