Arctic is warmest it's been in 10,000 years | BLOG Certified
Permafrost samples suggest Arctic is 2 C warmer than previous record highs thousands of years ago New research suggests Canada's Arctic is the warmest it has been in 10,000 years — and the temperatures are still climbing. The study was recently published in the scientific journal Nature Communications. Researchers studied permafrost samples in the Yukon near the Dempster Highway and determined that temperatures in the Arctic today are almost 2 C warmer than at any time in the past 10,000 years. The temperatures recorded today are even higher than the previous highs believed to have occurred during the early Holocene period, about 9,900 and 6,400 years ago, when Earth's axis was tilted more strongly toward the sun, the report states. Duane Froese, a professor at the University of Alberta and a co-author of the study, suggests that time period may actually be much longer. "I would guess we're getting back over 100,000 years since we've seen temperatures at least this warm," he said.
