125 days of navigable conditions by 2050

Ice-covered waters today, not so in 2050 according to the latest report from IPCC.

IPCC climate change report predicts two and a half time longer sailing season along the Northern Sea Route than today. Arctic has warmed twice the global rate in past three decades.

“The Northern Sea Route is predicted to have up to 125 days per year suitable for navigation by 2050,” says the latest report from the Intergovernmental Panel on Climate Change (IPCC) released on Monday. The report is not a wild-card scenario; “climate changes are already well underway,” reads the conclusion based on science- and research from around the globe.

Today the Northern Sea Route is open for navigation around 50 days, with an increase the latest four years. While the Russians have sailed interregional voyages from Murmansk and Arkhangelsk towards the north coast of Siberia for decades, transit shipping is relatively new. First ever bulk-vessel to sail the Northern Sea Route in transit was in 2010 with iron-ore from Kirkenes, Norway to China without making a stopover at a Russian port.

The scientists underline that predicted duration of ice-free periods in the Arctic Ocean is generally underestimated.

Shipping from major European ports to Shanghai is some 40 percent shorter via the Northern Sea Route compared with the Suez Canal. Shorter shipping distance cuts emissions, but increases the probability of shipping accidents with severe consequences for the fragile Arctic environment.

The ice-free period for shipping coincides with the breeding season of sea mammals and sea birds. Accidents with oil spill could therefore be disastrous.

Record low sea-ice was seen during summer in both 2007 and 2012.
