[ Watch the Video] Until now, it was presumed that the last glacial period denuded the Scandinavian landscape of trees until a gradual return of milder weather began and melted away the ice cover some 9000 years ago. That perspective is now disproved by research headed by Professor Eske Willerslev from the Centre for GeoGenetics, University of Copenhagen, Denmark, Laura Parducci from the University of Uppsala, Sweden, and Inger Greve Alsos from Tromsø University Museum,...

Scientists have found that the ground is drying out in a 13,700-year-old peat bog, just another sign, they say, of the Earth's warming climate. Ecologist Ed Berg says the peat bog is turning into forest. "There has been a big change," Berg said. Core samples taken from the bog show moss nearly 22 feet under the ground, with no sign of trees or shrubs growing here for centuries, Berg said. The bog could be covered by black spruce trees during the next 50 years, he said. Alaska is one state,...

The Blue Spruce or Colorado Spruce (Picea pungens), is a species of spruce native to western North America, from southeast Idaho and southwest Wyoming, south through Utah and Colorado to Arizona and New Mexico. It grows at high altitudes from 6,000 to 10,000 feet in altitude, though unlike Engelmann Spruce in the same area, it does not reach the alpine tree-line. It is most commonly found growing along stream sides in mountain valleys, where moisture levels in the soil are greater than the...
