It took almost a month for meltwater to accumulate atop Greenland’s ice sheet in the summer of 2006. It took only 90 minutes for all that water — a lake so large it could fill New Orleans’ Superdome more than 12 times over — to pour through a crack in the kilometer-thick ice below it and drain the lake dry.
At its height, the torrent exceeded that of Niagara Falls, and its rumbling triggered seismic instruments nearby. GPS equipment indicated that the westward flow of ice in the region briefly surged, a sign that the water drained down to the bedrock and temporarily lubricated the boundary between ice and rock.

One morning each week, a scientist takes a stroll on the barren upper slopes of Hawaii’s Mauna Loa volcano, a basketball-sized glass sphere in hand. At some point, the researcher faces the wind, takes a deep breath, holds it and strides forward while twisting open a stopcock. With a whoosh lasting no more than a Continue Reading →

The debate over climate change and its effects is often headline news. In the near future, scientists are concerned that the Earth will experience a continuing increase in global temperature. New research is showing that even if this increase is only a few degrees, it could have important repercussions for life on our planet.
Scientists from the Open University in the United Kingdom are studying climate change throughout Earth’s history. Their results indicate how dangerous modern global climate change might be for the future of life on Earth. In a new study published in the journal Geology, the researchers examined layers of sedimentary rocks from the ocean floor in order to unravel the story of climate change during the early Jurassic period.

Report May 2008 Atlantic Monthly by Lisa Margonelli Forty years ago, the steel mills and factories south of Chicago were known for their sooty smokestacks, plumes of steam, and throngs of workers. Clean-air laws have since gotten rid of the smoke, and labor-productivity initiatives have eliminated most of the workers. What remains is the Continue Reading →

WASHINGTON (AP) — Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests. The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday.
The report notes that a separate study by researchers at Stanford University estimated the number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the early Stone Age.
”This study illustrates the extraordinary power of genetics to reveal insights into some of the key events in our species’ history,” Spencer Wells, National Geographic Society explorer in residence, said in a statement. ”Tiny bands of early humans, forced apart by harsh environmental conditions, coming back from the brink to reunite and populate the world. Truly an epic drama, written in our DNA.”

 From the New Statesman The irony is extraordinary. At a time when world leaders are expressing grave concern about diminishing food stocks and a coming global food crisis, our government brings into force measures to increase the use of biofuels – a policy that will further increase food prices, and further worsen the plight of Continue Reading →
