(New Scientist) – It’s not just polar bears that are suffering as Arctic sea ice retreats.

Tens of thousands of reindeer in Arctic Russia starved to death in 2006 and 2013 because of unusual weather linked to global warming. The same conditions in the first half of November led to both famines, which killed 20,000 deer in 2006 and 61,000 in 2013.

Sea ice retreated and unseasonally warm temperatures contributed to heavy rains, which later froze the snow cover for months, cutting off the reindeer’s usual food supply of lichen and other vegetation.

“Reindeer are used to sporadic ice cover, and adult males can normally smash through ice around 2 centimetres thick,” says Bruce Forbes at the University of Lapland in Rovaniemi, Finland, who led the study. “But in 2006 and 2013, the ice was several tens of centimetres thick.”

This September saw the second-lowest level of sea-ice cover on record in the Arctic, and there is fear of another famine.

“If we see such events again this year, it could mean that they’re becoming more frequent,” says Forbes. “Now is the risk window, and if it happens again, it will be a major problem for traditional reindeer herders still suffering from losses in 2013.” [more]

ABSTRACT: Sea ice loss is accelerating in the Barents and Kara Seas (BKS). Assessing potential linkages between sea ice retreat/thinning and the region's ancient and unique social–ecological systems is a pressing task. Tundra nomadism remains a vitally important livelihood for indigenous Nenets and their large reindeer herds. Warming summer air temperatures have been linked to more frequent and sustained summer high-pressure systems over West Siberia, Russia, but not to sea ice retreat. At the same time, autumn/winter rain-on-snow (ROS) events have become more frequent and intense. Here, we review evidence for autumn atmospheric warming and precipitation increases over Arctic coastal lands in proximity to BKS ice loss. Two major ROS events during November 2006 and 2013 led to massive winter reindeer mortality episodes on the Yamal Peninsula. Fieldwork with migratory herders has revealed that the ecological and socio-economic impacts from the catastrophic 2013 event will unfold for years to come. The suggested link between sea ice loss, more frequent and intense ROS events and high reindeer mortality has serious implications for the future of tundra Nenets nomadism.

    Why? Do reindeer eat arctic ice?
