OSLO (Reuters) - Large tracts of ice on the Arctic Ocean have halved in thickness to just 1 meter (3 ft) since 2001, making the region more accessible to ships, a researcher said on Tuesday.

"There was loose ice everywhere we went," Ursula Schauer, leader of a scientific expedition aboard the Polarstern ice-breaker, told Reuters by telephone from the Arctic Ocean north of Siberia.

"All of these areas have previously had two meters of ice," said Schauer, who works at the Alfred Wegener Institute in Germany, of a trip from Norway around the North Pole and back towards Russia. The last major survey was in 2001.

Saving the California Redwoods, Again

Eureka, California - Daylight and mist chase away the last of the night’s moon shadows, revealing a fern-dominated woodland floor and a forest defined by ancient redwood trees. A sense of peace rains down from the dense canopy in showers of bird song. Centuries have passed untainted in this place. At more than 2,000 years old, Spooner has stood witness over a long era of harmony. Spooner is a redwood that lives in this beautiful grove nestled in the Nanning Creek watershed—a tributary of the Eel River. Spooner, named by those who visit it, is among the last of the unprotected giants. But just two miles away at the Pacific Lumber mill, plans are being made to see Spooner--and his ancient neighbors--chopped down and turned to lumber.
