Archeologists date human femur found in northern Britain to 10,000 years ago
(Phys.org) —A trio of archeologists has found that a human femur unearthed in a cave in the early 1990s, in northern Britain dates back to over 10,000 years ago. The combined team of researchers from the University of Nottingham ...
First-ever deep-drilling expedition to the Baltic Sea launches
Starting in September 2013, the Baltic Sea will be the scene of a unique scientific expedition. The Integrated Ocean Drilling Program (IODP) will set out drilling deeper into Baltic Sea sediments than ever before, all the ...
Tackling an Ice Age mystery
In the northern hemisphere, ice sheets ebb and flow in 100,000-year cycles, driven by varying amounts of sunlight falling on Earth's surface as its orbit and orientation toward the sun changes. But astronomical variations ...
Earth orbit changes key to Antarctic warming that ended last ice age
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, ...
Westerly winds and CO2 levels
The end of the last Ice Age was preceded by a gradual rise in atmospheric CO2. A new study supports the idea that a shift in the position, and increase in the intensity, of zonal westerly winds in the Southern hemisphere ...
Climate change occurring 10 times faster than at any time in past 65 million years
The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the speed of the change. Stanford climate scientists ...
Find helps scientists map waves of migration across the continents
The discovery of an "early modern human" dating from 40,000 years ago in a cave outside Beijing, and a comparison of the individual's DNA with that of populations around the globe, are providing new pieces in the puzzle of ...
Scientists solve a 14,000-year-old ocean mystery
At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, ...
