A tipping point for permafrost melting
Scientists had warned that a global average temperature rise of 2°C – occurring in the early 2040s* – was the maximum safe limit, beyond which climate change would race out of control. In earlier decades, tipping points were already being reached, such as the Arctic becoming ice-free during summer.* By 2044, an even greater and more serious threat is emerging in the form of greenhouse gases from melting permafrost.*
The quantity and extent of permafrost – defined as soil at or below the freezing point of water 0°C (32°F) for two or more years – had been well-documented. It was known that enough carbon lay trapped in Arctic ice to effectively double the level already in the atmosphere.* Vast stores of methane, a greenhouse gas over 25 times more potent than CO2 and 72 times more potent during the first 20 years,* were also present, with potential to drastically alter the climate.
Studies found that in many places, long-frozen soils were collapsing as they melted, forming erosional holes and landslides that revealed larger areas of permafrost beneath. This was accelerating the process of melting and greenhouse gas release, since these larger areas were then exposed to direct sunlight (pictured below).* Alongside this finding, evidence from Siberian caves suggested that a global temperature rise just 1.5°C (2.7°F) above current levels would see permanently frozen ground beginning to thaw over a vast area, representing a major tipping point.*
In addition to climate destabilisation, disastrous impacts on infrastructure are now being felt in the region with natural gas facilities, roads, railways and buildings in general all built upon permafrost vulnerable to thawing. Adjoining regions are witnessing significant changes, with Mongolia’s Gobi Desert becoming far wetter. In the decades ahead, this extremely arid area will come to resemble the present-day Asian steppes.
With large-scale permafrost melting underway, global temperatures are now on track to reach 3°C (5.4°F) above the 20th century average by the mid-2050s.* A genuine catastrophe is looming, threatening billions of lives.**

A transglobal highway and rail network has emerged
Midway through the 2040s, practically all major continents are connected to each other by road, rail and tunnel. This transglobal highway, as it comes to be known, was never a definite goal nor an individual project. It was instead formed by long-term, incremental steps, as countries around the world reached across their borders and waterways to formerly distant neighbours. Over the years, from the mess of highways and railways criss-crossing the globe, a specific route began to emerge, uniting every populated continent with the exception of Australia.*
Arguably one of the first steps in this process was the Trans-Siberian Railway, which began construction in 1890. This was a network of railways connecting Moscow with the Russian Far East and Sea of Japan. It became the world's longest railway, stretching 9,300 km (5,800 mi), with expansion continuing more than a century later.*
Another major transport network to emerge during the 20th century was the Pan-American Highway. This linked the mainland nations of the Americas – extending from Prudhoe Bay in Alaska to the lower reaches of South America.* With a total length of 48,000 km (30,000 mi), it became the world's longest "motorable road". However, because of the Darién Gap, it was not possible to cross from Central America to South America by traditional motor vehicle.
The Channel Tunnel (an idea first proposed in 1802), was officially opened in 1994. This provided the first direct physical link between Britain and mainland Europe since the Ice Age. This megaproject included the longest undersea portion of any tunnel in the world, at 37.9km (23.5 mi) in length.*
In 2000, the Øresund Bridge was completed.* This became the longest combined road and rail bridge in Europe and connected the major road networks of Scandinavia to those of Central and Western Europe. It was followed by the Fehmarn Belt Fixed Link, providing a more direct route from Germany to Sweden and Norway.*
By the 2020s, several major new connections were being completed around the world. One notable project was the Sunda Strait Bridge, linking the Indonesian islands of Sumatra and Java.* This crossing utilised islands in the strait as stepping stones. It carried a six lane highway and a double-track railway and cost upwards of $12bn. The most extensive portion – a suspension bridge – had a central span of 3,000 m (9,800 ft), making it the second longest suspension bridge in the world at the time.
By 2025, another major link was completed - this time in the Mediterranean. The Strait of Gibraltar Tunnel had been in the planning stages for decades, but in the mid-2010s it finally got off the ground. Negotiations between Spain and Morocco were drawn out, but an agreement over costs and economics was finally reached. Building the tunnel posed serious engineering challenges, mainly because of the deep seabed found in the strait: around 300 metres in the shallowest areas. A car tunnel was ruled out, since removing exhaust fumes from that depth proved infeasible. The engineers behind the project also determined that, in order to graduate the slope, the entrances on either side would need to be almost 3km away from the coast. Despite rising costs, the project continued to move forward, construction technology overcame the structural challenges, and, midway through the 2020s, the first trains made the journey from one continent to another.*
Meanwhile, road and rail projects were growing outwards on both sides, with new routes expanding through Africa and existing routes being strengthened in Western Europe.* The 2020s also saw completion of a major bridge linking Africa with the Middle East, known as the Bridge of the Horns.*
As it became more developed, China greatly expanded its infrastructure, with hundreds of miles of railtrack being added each year.* Major new transport links began to unify Southeast Asia as a whole. In the 2030s, Japan was connected to the mainland by rail for the first time. This was achieved via the new Sakhalin–Hokkaidō Tunnel, running between the Japanese island of Hokkaidō and the Russian island of Sakhalin. A shorter tunnel connecting Sakhalin to mainland Russia had been completed years before which, coupled with the new 42 km long rail tunnel, opened new trade routes between Japan and continental Asia. Like Gibraltar, many issues had to be overcome, primarily political ones. For years, there was debate as to the economic usefulness of the tunnel, until the demand for such a crossing manifested itself, at which point it was finally agreed that construction would be productive.* Thanks to the long-existing Seikan Tunnel, all four of the main Japanese islands were then connected to Russia.
Another huge project of this period was the Malacca Strait Bridge. This connected Sumatra (the largest island entirely within Indonesia) to western Malaysia and mainland Asia. Spanning nearly 128km (80 mi), it became the longest sea-crossing bridge in the world. Combined with the Sunda Strait Bridge (see above), this greatly expanded the Indonesian economy - providing new markets and access to China.*
By the 2040s, Japan saw completion of its second mainland connection, this time between it and South Korea. This project had by far the most problems of any major link, due to the differing political and cultural climates of the two countries. Trade and travel necessity ultimately pushed the project along, after considerable delays.*
One of the most ambitious of all the transglobal highway projects – the Bering Strait Crossing – was also completed early in this decade. A joint venture between Russia and the United States, it was the first direct infrastructure link between the two countries. It would consist of three tunnels, connecting the continents via the Diomede Islands.* During its development, rising global temperatures actually benefited the project, having made construction easier in the warming Siberian landscape. Coupled with the crossing was a series of road and rail projects branching out through Eastern Russia – eventually joining up with China, Japan and all the way through to Europe. In other words, it was now possible to board a train in London and travel directly to New York City, via Moscow and Yakutsk.*
Ironically, the last connection of the transglobal highway to be completed was actually the shortest. For decades, the Darién Gap in Panama, a near-impenetrable wall of jungle and brush, had blocked road connections between North and South America. Demand was slow to materialise for the connection, and environmental protection prohibited a land crossing. In the early 2040s, a compromise was reached, as the influx of climate change refugees from drought-stricken South American countries demanded an easy path northwards. A bridge was constructed across the Gulf of Urabá between Panama and Columbia, bypassing the Darien Gap.*
By 2044, people can travel to all corners of the globe using direct road or rail links. However, geopolitical stresses are beginning to slow the expansion of new connections. Resource wars have made the opening and closing of national borders increasingly frequent and unpredictable, at times cutting off sections of the network. Despite this, it continues to be largely operational as a whole, due to its sheer size and extent. In a world wracked by environmental catastrophe, it serves as a lifeline for many countries - since food, water, metals, minerals and other natural resources can be easily and quickly moved from more prosperous regions. Although the transglobal highway is stagnating in growth, it remains a vital piece of infrastructure for decades to come.
Five-year survival rates for bowel cancer are approaching 100%
In the early 21st century, bowel cancer was the third most common cancer in the world. As of 2008, there were over 1.2 million new cases and 608,000 deaths globally each year. It was more common in developed countries, where around 60% of cases were diagnosed. The highest rates were found in Australia, New Zealand, Europe and the US and lowest rates in Africa and South-Central Asia.
Risk factors for bowel cancer were known to include older age (50+), male gender, high intake of fat, alcohol or red meat, obesity, smoking and a lack of physical exercise. Approximately 10% of cases were linked to insufficient activity. The risk for alcohol appeared to increase at greater than one drink per day.
Treatment for bowel cancer would depend on how advanced a particular case was – but generally included surgery, chemotherapy and radiation. For those with incurable cases, a range of palliative care treatments were available for reducing pain and improving quality of life.
Research into bowel cancer led to a marked improvement in survival rates during the late 20th century, a trend which continued into the 21st. Rapid falls in genome sequencing costs,* together with increasingly sophisticated mouse models,* provided ever more valuable insights into the nature and mechanisms of the illness.
New treatments and earlier diagnoses were made possible using targeted nano-particles** and eventually nanorobotics for delivering medicines with greater precision and fewer side effects. Five-year survival rates are now approaching 100% in the US,* with many other countries not far behind.*
