Melting glaciers blamed for subtle slowing of Earth's rotation

By Will Dunham WASHINGTON (Reuters) - The melting of glaciers caused by the world's rising temperatures appears to be causing a slight slowing of the Earth's rotation in another illustration of the far-reaching impact of global climate change, scientists said on Friday. The driving force behind the modest but discernible changes in the Earth's rotation measured by satellites and astronomical methods is a global sea level rise fueled by an influx of meltwater into the oceans from glaciers, the researchers said. "Because glaciers are at high latitudes, when they melt they redistribute water from these high latitudes towards lower latitudes, and like a figure skater who moves his or her arms away from their body, this acts to slow the rotation rate of the Earth," Harvard University geophysicist Jerry Mitrovica said.

Northrop says it will bid if Pentagon opens GPS satellite tender

By Andrea Shalal PALMDALE, Calif. (Reuters) - Northrop Grumman Corp this week said it would bid if the U.S. Air Force opens a fresh competition for next-generation GPS satellites next year, as expected, and perhaps later on a new ground control system. Tom Vice, president of Northrop's Aerospace Systems division, said he expects the Air Force to launch a competition for new Global Positioning System (GPS) satellites, and Northrop was ready to participate. Northrop already builds satellites for the U.S. intelligence community and is building the powerful new James Webb telescope for NASA.

Traces of a 'Lost' Stonehenge Appear in Rock Quarry

A few tantalizing pieces of evidence hint that there may have been an earlier, lost precursor to Stonehenge somewhere in Wales. Some of Stonehenge's bluestones were mined from a rocky outcrop called Craig Rhos-y-felin, part of Preseli Hills in Wales. This raises the possibility that one or two of the bluestones from Stonehenge may have first been used in some other, earlier henge in Wales before being removed from that monument and transported to the Salisbury Plain in England.

Nearly 200 nations near a deal to slow global warming

LE BOURGET, France (AP) — France presented negotiators from nearly 200 nations with what it called a "final draft" of an unprecedented climate deal to slow global warming and urged them to approve it on Saturday. The deal would slow rising temperatures and sea levels, and eventually hold man-made emissions to the levels that nature can absorb.
