What problems will we face in 2050?

The economic impact to regions will be profound, and climate refugees could become the norm. Pressure is already growing on cities, as urban populations grow. If climate change forces mass migration, then existing infrastructure, services and economies may be stretched to breaking point.

LOST CITIES

You don’t need to look very hard in a place like Miami to see how cities are changing in the 21st Century – rising sea levels are gradually making some of them disappear. Fuelled by climate change, not only are floods becoming more common in the streets, but the changing weather patterns have also influenced building design. Aside from more seawalls, the city is requiring all new buildings be built with their first floor built higher. But that’s all a sticking plaster – if current trends continue, we may have to come to terms with losing whole swathes of cities, islands and low-lying regions such as Bangladesh. The economic impact to regions will be profound, and climate refugees could become the norm. Pressure is already growing on cities, as urban populations grow. If climate change forces mass migration, then existing infrastructure, services and economies may be stretched to breaking point.

THE EVOLUTION OF SOCIAL MEDIA

Social media has complicated the way we communicate for the better part of a decade. And it’s not going anywhere anytime soon, given that most people get their news from it now. That’s before we even get into the mess of online harassment, as well. What might social media look like in 30 years, and by that time, what are some threats it might pose?

A world with no privacy, for one. That’s one problem we’re already seeing. And besides weathering away our sense of and desire for anonymity and privacy, social media brings with it the many problems of cyberbullying too. Many charities and non-profit organisations across the world have mobilised in the fight against internet trolls, but it’s an open question about whether law enforcement agencies and the social media companies can fix it or whether it will get worse. Then there’s also the problem of our information diet to consider: if the status quo of ubiquitous fake news remains, how will that shape how people see the world? If individuals spend months, years, even decades of their life exposed only to unreliable news sources, it does not augur well for civilised society and debate. That said, given how fast social media has arrived in the world, an optimist may suggest that those problems could soon be resolved. In 30 years’ time we may be dealing with social media issues that we’ve not even considered yet. After all, Facebook is only 13 years old.

NEW GEOPOLITICAL TENSIONS

The past year has seen a complete upset of our geopolitics’ fragile balance. That could make the global stability of the next couple of decades a complete question mark. North Korean missile launches. Thousands of refugees crossing borders to flee turmoil. Hackers meddling in other nations’ elections. Rising nationalist sentiment worldwide. Headlines in 2016 (and so far, 2017) have been dominated by never-ending political drama that’s been fuelling a ‘geopolitical minefield’ and an ‘unprecedented geopolitical shift’ – whether it’s managing unpredictable North Korea, the plight of Syrian refugees, or Britain’s transition from the European Union. Throw in widespread hacking, nuclear missiles and other dangerous technology, and it’s easy to see why maintaining basic diplomacy becomes vital.

SAFE CAR TRAVEL

Despite all the rapid urbanisation and talk of bullet trains and fantastical technology like the Hyperloop coming to the fore, the car isn’t going anywhere – and in fact, in the next couple decades, there will be even more of them on the road.

Driverless car technology is swiftly rolling out, with major tech companies and automakers aggressively seeking to debut human-free vehicles in coming years. But in addition, the sheer number of cars – self-driving or not – is going to skyrocket, studies show. In countries like China that are seeing a growing middle class, the environmental and infrastructural needs that an increasingly road-faring population demands is going to be a grand challenge. How do we ensure safety, fight pollution, and make sure driverless cars aren’t a menace on the road?
