Arctic Lake Sediment Shows Warming, Unique Ecological Changes in Recent Decades
A University of Colorado at Boulder-led analysis of a 200,000 year-old sediment core from a Baffin Island lake indicates warming temperatures in the Arctic due to human activity are overriding a natural cooling trend in the region. (Photo by Jason Briner, University at Buffalo)An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, accordi
