Holocene Perspectives on a Warming Artic by Dr. Jamie McFarlin

Описание к видео Holocene Perspectives on a Warming Artic by Dr. Jamie McFarlin

The Arctic is exceptionally sensitive to changes in the global climate system. The Arctic warms 2-3x faster than the global average, with implications of this more rapid warming for albedo, sea level, carbon cycling, and beyond. This talk will discuss aspects of ongoing and predicted changes in the Arctic given sustained warming, anchored in evidence from the Holocene epoch (~10,000 years ago to present) for how warming-driven changes in the recent geologic past unfolded. In particular, this work will highlight recent evidence for major changes in lake methane cycling across Greenland during the Holocene and what it portends for methane generation in Arctic lakes over the coming century.
