Increased sediment accumulation rates and climatic forcing in the central Andes during the late Miocene
Cornelius E. Uba et al., University of Potsdam, Potsdam 14476, Germany. Pages 979-982.
Uba et al.'s research contributes to the better understanding of the interplay between tectonics and climate in the development of the Andes, in South America. Scientists have, hitherto, always explained the Andean evolution and sedimentation as a result of tectonics. Uba et al. have collected data that document increased sedimentation rate as a result of variability in climate between 8 and 6 million years ago. These results change the previous understanding of the Andean evolution and show climate is also an important factor in the development of the Andes.
Present-day temperatures in northern Scandinavia during the last glaciation
K.F. Helmens et al., Stockholm University, Physical Geography and Quaternary Geology, Stockholm, SE-106 91, Sweden. Pages 987-990.
The knowledge of changes in climate during the last ice age (between ca. 120,000 and 10,000 years ago) has enormously improved over the last decade through studies on Greenland ice cores and North Atlantic deep-sea sediments. On land, widespread erosion generally erases the geological record. Helmens et al. present results from a unique sediment sequence in northern Finland that significantly changes the present concept of climate variability on the northern European continent. Their data provide evidence of a period of rapid climate warm
