Melting Arctic ice could open up new eco-friendly international shipping routes that BYPASS the Russian-controlled Northern Sea Route, study finds
- Parts of the Arctic that were covered in ice year-round will be ice-free for months
- This could mean more eco-friendly trade routes that bypass Northern Sea Route
- Russia contends that the Northern Sea Route falls primarily within its own waters
From starting wildfires to melting glaciers, the negative effects of climate change are well documented, but a new study suggests there could be at least one positive.
Researchers say that, in as few as two decades, parts of the Arctic that were once covered in ice year-round will be reliably ice-free for months on end due to global warming.
A result of this could be shorter, more eco-friendly maritime trade routes that bypass the Russian-controlled Northern Sea Route.
This would reduce the shipping industry’s carbon footprint and weaken Russia’s control over trade routes through the Arctic, they say.
Examples of routes through the Arctic that will be made more navigable by melting ice include Transpolar Sea Route and Northwest Passage.

Because of heavy regulations along the Northern Sea Route from the Russians, shipping companies often instead use the longer Suez and Panama canal routes
The study was conducted by climate scientists at Brown University in Providence, Rhode Island, who worked with a legal scholar at the University of Maine School of Law.
THE NORTHERN SEA ROUTE
The Northern Sea Route is a shipping lane officially defined by Russian legislation between the Atlantic Ocean and the Pacific Ocean.
It runs along the Russian Arctic coast from Murmansk on the Barents Sea, along Siberia, to the Bering Strait and Far East.
The route lies in Arctic waters and parts are free of ice for only two months per year.
Along with the warming in the Arctic, the passage can be used more and more for shipping.
Energy and time savings compared to the normally used route vie Suez Canal are about 30-40 per cent.
The experts stress that the Arctic’s changing climate will endanger countless species that thrive in sub-zero temperatures, so it’s not entirely ‘good news’.
‘There’s no scenario in which melting ice in the Arctic is good news,’ said study author Professor Amanda Lynch at Brown University.
‘But the unfortunate reality is that the ice is already retreating, these routes are opening up, and we need to start thinking critically about the legal, environmental and geopolitical implications.’
Lynch and colleagues used computer modelling to determine likely outcomes of global actions to halt climate change in the coming years.
The authors based their projections on four emissions scenarios, ranging from high emissions to the more constrained 2.7°F (1.5°C) of warming.
Projections showed that unless global leaders successfully constrain warming to 2.7°F over the next 43 years, climate change will likely open up several new routes through international waters by 2065.
The likelihood of a navigable season outside Russian waters increased by almost 30 per cent, with 99 per cent confidence by 2065 in the highest emissions scenario.
But parts of the Arctic are warming so quickly that they will be reliably ice-free for months on end in as few as two decades, which would be enough time to understake shipping journeys.
According to legal scholar Charles Norchi, changes brought on by global warming could have major implications for world trade and global politics, especially in light of Russia’s war on Ukraine.
Since 1982, the United Nations Convention on the Law of the Sea has given Arctic coastal states – including Canada and Russia – enhanced authority over primary shipping routes.
Article 234 of the convention states that in the name of ‘the prevention, reduction and control of marine pollution from vessels’, countries whose coastlines are near Arctic shipping routes have the ability to regulate the route’s maritime traffic, so long as the area remains ice-covered for the majority of the year.
Norchi said that for decades, Russia has used Article 234 for its own economic and geopolitical interests; for example one Russian law requires all vessels passing through the Northern Sea Route to be piloted by Russians.

The country also requires that passing vessels pay tolls and provide advance notice of their plans to use the route.
The heavy regulation is one among many reasons why major shipping companies often bypass the route’s heavy regulations and high costs and instead use the Suez and Panama canals – longer, but cheaper and easier, trade routes.
But as the ice near Russia’s northern coast begins to melt, Norchi said, so will the country’s grip on shipping through the Arctic Ocean.
‘The Russians will, I’m sure, continue to invoke Article 234, which they will attempt to back up with their might,’ Norchi said.
‘But they will be challenged by the international community, because Article 234 will cease to be applicable if there’s no ice covered-area for most of the year.’

Also, shipping will move out of Russian territorial waters and into international waters, which Russia ‘can’t do much’ about.
According to Lynch, previous studies have shown that Arctic routes are 30 per cent to 50 per cent shorter than the Suez Canal and Panama Canal routes, with transit time reduced by an estimated 14 to 20 days.
That means that if international Arctic waters warm enough to open up new pathways, shipping companies could reduce their greenhouse gas emissions by about 24 per cent while also saving money and time.
According to the team, it’s better to ask questions about the future of shipping now, rather than later, given how long it can take to establish international laws.
For context, it took 10 years for world governments to negotiate the Convention on the Law of the Sea.
‘Flagging these coming changes now could help prevent them from emerging as a crisis that has to be resolved rapidly, which almost never turns out well,’ Lynch said.
‘To actually craft international agreements with some forethought and deliberation is certainly a better way to go.
The new study has been published today in the Proceedings of the National Academy of Sciences.
WHY IS SHIPPING PREDICTED TO INCREASE IN THE ARCTIC?
In August 2016, the first large cruise ship travelled through the Northwest Passage, the northern waterway linking the Atlantic and Pacific oceans.
The following year, the first ship without an icebreaker plied the Northern Sea Route, a path along Russia’s Arctic coast that was, until recently, impassable by unescorted commercial vessels.
In recent decades parts of the Arctic seas have become increasingly ice-free in late summer and early fall.
As sea ice is expected to continue to recede due to climate change, seasonal ship traffic from tourism and freight is projected to rise.
Travel through the Arctic Ocean is already beginning, with the Russian route having the most potential for commercial ships.
The Northern Sea Route had more than 200 ships from 2011 to 2016, all of which were large vessels.
More than 100 vessels passed through the Northwest Passage during that time, with more than half being small, private vessels like personal yachts.
Experts say even the North Pole could be passable in a matter of decades.
