Local sources major cause of US near-ground aerosol pollution

A new NASA study estimates that most ground-level particulate pollution in the United States stems from regional sources in North America and only a small amount is brought to the country from other parts of the world.

Noah's Ark flood spurred European farming

LONDON (Reuters) - An ancient flood some say could be the origin of the story of Noah's Ark may have helped the spread of agriculture in Europe 8,300 years ago by scattering the continent's earliest farmers, researchers said on Sunday.

Using radiocarbon dating and archaeological evidence, a British team showed the collapse of the North American ice sheet, which raised global sea levels by as much as 1.4 meters, displaced tens of thousands of people in southeastern Europe who carried farming skills to their new homes.

The researchers said in the journal Qua >> Read the Full Article
