Until recently, the thick ice of the Arctic Ocean still blocked the shortest shipping route between Asia and North America and Europe.
A direct route through the Arctic would allow icebreakers to connect the world’s two largest oceans with a 20% shorter distance than the existing Northern Sea Route.
According to foreign media reports, experts recently said that by the middle of this century, the Arctic Ocean’s sea ice will become so thin that it will be possible for ships to sail directly through the Arctic for the first time. Scientists from the University of California said that around 2050, the Arctic Ocean’s sea ice will become fragile enough to allow icebreakers to carve out a direct route connecting the Atlantic and Pacific Oceans. In fact, cargo fleets could completely bypass the Arctic without needing icebreakers, as the sea ice will have largely retreated by then.
The research findings were recently published in the Proceedings of the National Academy of Sciences. Shipping companies have welcomed the news, as navigating through the Arctic could save them significant time and costs. However, environmentalists are concerned, fearing that local wildlife could face catastrophic impacts, and that numerous oil companies may flock to the region. The gradual thawing of the Arctic will also heighten tensions among Europe, Canada, and Russia over Arctic shipping routes and resource issues, which are already strained.
Last summer, Arctic sea ice reached a historic low, and calculations show that even if global agreements to gradually reduce carbon dioxide emissions are reached now, this melting trend will continue. The lead researcher of this study, Professor Laurence Smith, said that by 2050, ships will be able to freely traverse the northernmost parts of the world map. He believes that only light icebreaking ships will be needed to navigate the Arctic. He said, “No one has ever considered sailing through the Arctic. This is a completely unexpected possibility.”
Scientists used seven well-established climate models to calculate changes in Arctic sea ice thickness between 2040 and 2059. Their research even involved computer simulations to determine optimal shipping routes in September, when Arctic sea ice is at its thinnest.
The calculations showed that by the middle of this century, most ocean-going vessels will be able to navigate near the North Pole without the help of icebreakers and dock along Russia’s Arctic coast. This route will be about 40% shorter than the existing Suez Canal route. Even the famously treacherous Canadian Northwest Passage is expected to open by then, allowing ice-strengthened ships to pass through smoothly, and even some non-reinforced vessels may be able to navigate the area.
Another expert involved in the study, Scott Stephenson, said that currently, icebreakers only sail through the Arctic during specific times of the year. He said, “We’re talking about future scenarios where regular ships can navigate, at least in certain years, without the accompaniment of icebreakers. That’s currently unimaginable.”
Until recently, the thick ice of the Arctic Ocean still blocked the shortest shipping route between Asia and North America and Europe. However, over the past two years, Arctic sea ice has significantly thinned, allowing ordinary ships to enter the peripheral areas of the region under the escort of icebreakers during certain summer periods. Last summer, a total of 46 cargo ships successfully completed the Northern Sea Route. If this new trans-Arctic route becomes operational in the future, it will make shipping significantly faster.
A direct route through the Arctic will allow icebreakers to connect the world’s two largest oceans with a 20% shorter distance than the existing Northern Sea Route. Professor Smith said that even if greenhouse gas emissions are reduced immediately, the opening of the Arctic shipping route is inevitable. He said, “No matter which greenhouse gas emission model you look at, by the middle of this century we will cross a critical threshold where Arctic sea ice will significantly thin, allowing lightweight icebreakers to navigate freely in the region.”
Previously, the international environmental organization Greenpeace had been working to oppose and prevent oil and gas development in the Arctic. In a petition campaign launched by the environmental group, 2.8 million people have signed so far, calling for “the creation of a protected area around the Arctic Ocean and a ban on drilling and environmentally destructive industrial activities in the Arctic seas.”
For the past 800,000 years, the Arctic Ocean has been covered by thick ice. Due to human reliance on fossil fuels leading to gradual climate change, the ice in the Arctic region has begun to melt. In the near future, the Arctic Ocean will experience ice-free conditions for the first time since the emergence of humans. This change will not only impact the people, polar bears, and other life forms living in the Arctic, but will also have significant effects on people across the entire planet.
The vast sea ice of the Arctic Ocean reflects a large amount of sunlight, helping to cool the Earth and stabilize the climate system, which is the foundation of our food supply. Therefore, protecting the Arctic’s ice is protecting our own future.
The melting of Arctic sea ice itself does not cause global sea levels to rise, but the Earth will lose a vast expanse of reflective white ice, losing an important cooling mechanism. Worse still, because seawater absorbs heat, the ice-free Arctic Ocean will help heat the Earth rather than cool it.
