A recent study published in the September 4 issue of Science magazine is yet another indicator that the Arctic is in crisis. A team of scientists found that temperatures in the Earth’s vast northernmost region – which includes the Arctic Ocean and parts of Alaska, Canada, Russia, Greenland, and the Scandinavian countries in Northern Europe – have reversed a long-term cooling trend and are now the warmest they’ve been in at least 2,000 years.
The study’s authors include the renowned Darrell S. Kaufman, of the School of Earth Sciences and Environmental Sustainability at Northern Arizona University, and David Schneider of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.
The Arctic cooling period had lasted for 2,000 years and was reversed during the 20th century, with four of the five warmest decades in the region occurring between 1950 and 2000.
