The Arctic Is Getting Greener But Its Caribou Are Dying

By Lisa Cumming

Some Indigenous communities rely on the caribou hunt.

Given that caribou are herbivores, it seems possible that populations in the Arctic might actually benefit from climate change—there'd be more green stuff around for them to eat. Well, no. A team of researchers has released a new studyfinding the changes to vegetation that come with melted sea ice seem to put the animals' food sources in danger. 

Changed Arctic, changed world

By Martin Sommerkorn

The question is no longer if Arctic change is going to hit the rest of the world. The question is how much it is going to sting

 

t is likely that many people alive today will see the end of the Arctic as we know it. The vast expanses of summer sea ice trod by polar bears, the pods of narwhals coursing by, the day-long herds of caribou crossing the tundra, all are threatened by current and future climate change. This change will have an impact on life in the Arctic, and in the rest of the world. This is the stark conclusion from the most complete assessment of Arctic climate in six years.

Russian scientists have found marine plants, which got adopted to living without light and studied whether the global warming threatens the Arctic’s nature

MURMANSK, April 24. /TASS/. Scientists of the Murmansk Marine Biology Institute during a unique expedition collected most interesting data about the Arctic’s flora and fauna. The researchers found marine plants, which got adopted to living without light, they learned that whales head for the Arctic ices not only for food, and studied whether the global warming threatens the Arctic’s nature.

Fundamental Arctic

In a conversation with TASS, the Institute’s deputy director, Pavel Makarevich, said the institute did not have expeditions of the kind after 1987. "The state now has resumed financing of fundamental research, and thus we received money for our expedition - we have made very detailed tests - after 1987 we had a gap in this work," the scientist said.

A big patch of plastic garbage has been discovered in the Arctic

This is why we can’t have nice things

 

Scientists have discovered a new garbage patch — this time floating in the remote, frozen reaches of the Arctic. Plastics discarded in Europe and the East Coast of North America slowly drift to a watery graveyard north of Norway, according to a new study — endangering wildlife already struggling to adapt to a changing climate. 

Arctic river ice deposits rapidly disappearing

Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.

River icings form when Arctic groundwater reaches the surface and solidifies on top of frozen rivers. They grow throughout the winter until river valleys are choked with ice. Some river icings have grown to more than 10 square kilometers (4 square miles) in area - roughly three times the size of New York's Central Park - and can be more than 10 meters (33 feet) thick.

In the past, river icings have melted out around mid-July, on average. But a new study measuring the extent of river icings in the U.S. and Canadian Arctic shows most river icings disappeared 26 days earlier, on average, in 2015 than they did in 2000, melting around mid-June. In addition, the study found most icings that don't completely melt every summer were significantly smaller in 2015 than they were in 2000. Watch a video of river icings here.
