At least 51 killed as tornado tears through Oklahoma, leaving miles of debris

An enormous tornado roared through the Oklahoma City suburbs, killing at least 51 people, including 20 children Monday. The twister pulverized entire city blocks, left behind miles of mangled cars and splintered wood, and destroyed an elementary school where seven children were found dead.

Great read and video of the researchers in Mongolia.

Eight hundred years ago, relatively small armies of mounted warriors suddenly exploded outward from the cold, arid high-elevation grasslands of Mongolia and reshaped world geography, culture and history in ways that still resound today. How did they do it?

Tree-ring scientists at Columbia University’s Lamont-Doherty Earth Observatory have worked in Mongolia since 1995. In 2010, Lamont researcher Neil Pederson and Amy Hessl of West Virginia University were seeking old trees for a study of wildfire history. High in the Khangai Mountains, north of the steppe where the long-disappeared Mongol capital of Karakorum once lay, they explored a nearly solid-rock plain of hardened lava left by a volcanic eruption some 8,000 years ago. Growing out of fissures and thin soils were thousands of gnarled, stunted larches and Siberian pines–a tree-ring scientist’s treasure. Annual rings of many species reflect rainfall or temperature in predictable ways. These can be read like books; and trees in the driest, harshest sites like this are exquisitely sensitive to rain, live to extraordinary ages, and leave trunks that may stand for centuries after they die. They are truly ancient manuscripts, writ with a fine hand.

Pederson and Hessl analyzed 17 trees to chart a yearly record of rainfall back to 658 AD. They saw that from 1211-1230—the exact time of the Mongols’ rise—central Mongolia saw one of its wettest periods ever. That time also was unusually warm, as shown by a

 2001 paper from other Lamont researchers.

Byrd’s First Antarctic Expedition 1928.

“In 1928, Admiral Byrd began his first expedition to the Antarctic involving two ships, and three airplanes: Byrd’s Flagship was The City of New York; a Ford Trimotor called the Floyd Bennett (named after the recently deceased pilot of Byrd’s previous expeditions); a Fairchild FC-2W2, NX8006, built 1928, named “Stars And Stripes” (now displayed at the Virginia Aviation Museum, on loan from the National Air and Space Museum); and a Fokker Universal monoplane called the Virginia (Byrd’s birth state).

A base camp named “Little America” was constructed on the Ross Ice Shelf and scientific expeditions by snowshoe, dog-sled, snowmobile, and airplane began. Photographic expeditions and geological surveys were undertaken for the duration of that summer, and constant radio communications were maintained with the outside world. After their first winter, their expeditions were resumed, and on 28 November 1929, the famous flight to the South Pole and back was launched. Byrd, along with pilot Bernt Balchen, co-pilot/radioman Harold June, and photographer Ashley McKinley, flew the Ford Trimotor to the South Pole and back in 18 hours, 41 minutes. They had difficulty gaining enough altitude, and they had to dump empty gas tanks, as well as their emergency supplies, in order to achieve the altitude of the Polar Plateau. However, the flight was successful, and it entered Byrd into the history books. After a further summer of exploration, the expedition returned to North America on 18 June 1930. A 19 year-old American Boy Scout, Paul Allman Siple, was chosen to accompany the expedition. Unlike the 1926 flight, this expedition was honored with the gold medal of the American Geographical Society. This was also seen in the 1930 film With Byrd at the South Pole in which it covered his trip there.

Byrd, by then an internationally recognized, pioneering American polar explorer and aviator, served for a time as Honorary National President (1931—1935) of Pi Gamma Mu, the international honor society in the social sciences. In 1928, he carried the Society’s flag during a historic expedition to the Antarctic to dramatize the spirit of adventure into the unknown, characterizing both the natural and social sciences”
