Have we passed peak London?

London has grown steadily for the past 30 years, in people, jobs and self confidence. Population growth has been driven both by in-migration (more people moving to London than moving away) and by natural change (more births than deaths). International migration – both EU and non-EU – has been a major factor in the city’s growth, outweighing domestic migration, where London has been a net exporter of people.

For some, London’s growth should be celebrated as evidence of its success as a global city: it’s a jobs machine; an economic powerhouse; a gateway to the UK; a generator of fiscal surpluses for the whole nation. For others, London is a “dark star”, draining the rest of the UK of people, talent, public spending and media attention. Its growth is seen as unnatural and unbalanced, leading to a large and increasing gap in opportunities, wealth and income between London and the rest of the UK.

These debates are familiar and entrenched – but perhaps they are becoming out of date. There are already some indications that London is at the edge of a major inflection point: could it be that, rather than continuing to grow, London is about to stall, or even go into decline?

Prime and decline

For much of the 20th century, London was in decline. After World War II, the city’s manufacturing and goods-handling economy faltered. Between 1966 and 1974, London’s manufacturing employment fell by 27 per cent - a loss of 390,000 jobs. Planning and economic policy favoured dispersal, more balanced regional growth and the creation of New Towns and Garden Cities outside of London. The capital’s population declined most rapidly in the 1970s: over the decade, the capital experienced a net loss of 740,000 people – that’s 10 per cent of the city’s population.

Few, if any, commentators foresaw the change that came in the mid-1980s, as the long decline in both population and jobs slowed and then reversed. Sentiment began to shift; London began to look like a place to be, rather than a city to flee. The completion of the single market, freedom of movement and EU expansion helped London to develop a specifically European economic and cultural role, alongside its status as a global city.

Globalisation – the easier movement of people, goods, services, money and ideas across borders – boosted London’s role as a centre for communication and control, and as a meeting place within the world economy. Language, time zone and cultural assets all helped. English became the global business language. London’s working day helpfully overlaps with Asia in the morning and with North America in the afternoon. And the city’s liveability, cosmopolitanism and cultural offer all made it attractive as a location for decision-makers, skilled workers and students. Complementing this economic growth, by the turn of the 21st century policy shifted to favour cities.

Without the benefit of hindsight, it is much harder to decide if we are now approaching a move in the opposite direction. There is some evidence of this: in the year to mid-2017, London’s population experienced the slowest rate of growth in over a decade, at only 0.6 per cent. International migration to London has declined to a net gain of only 83,000 individuals in 2016-17, though it remains the largest contributor to growth in the capital.

National Insurance Number registrations by people coming from overseas to work are dropping, with EU registrations falling 25 per cent year-on-year to the first quarter of 2018. Net internal migration saw a balance of 107,000 people leave London for the rest of the UK, more than 14 per cent higher than the previous year. Over 4.7m international visitors came to the capital in the final three months of 2017 - a noticeable 5.7 per cent fall compared with 2016.

Passenger journeys on public transport are also decreasing slightly. Falls in ridership may be an early sign that London is at or close to reaching peak growth. Or they may be driven by other factors – for example by changing work or commuting patterns, generational differences in housing choice and lifestyle or the rapid rise of ride-hailing apps.

Still the main attraction

Yet despite concerns over the impacts of Brexit, London’s economy has proved resilient, with unemployment continuing to fall and job numbers increasing. The number of jobs increased to 5.863m in the final quarter of 2017, a 98,000 (1.7 per cent) increase from a year earlier and a new record-high. The employment rate in London stood at 75.2 per cent in the three months to March 2018, also a record high. Job growth is predicted to continue, as job vacancies in the capital have reportedly increased by over 14 per cent in the year to the second quarter of 2017.


London continues to be the most productive region in the UK, although many new jobs have been created in low-pay and low-productivity sectors. And it’s still a very competitive destination for investment. In the EY 2016 European Attractiveness Survey, 57 per cent of almost 1,500 business leaders sampled put London among the top three cities for foreign direct investment in Europe.

So is London’s long boom finally coming to an end? Like any demographic or economic turning point, this one will be easier to spot in hindsight. If current trends continue, then London’s growth may slow considerably - or even perhaps reverse - over the next 30 years. Brexit could affect this in unforeseen ways - although the economic impacts of Brexit are likely to be worse outside London than within. And for the time being, London is still growing in terms of people, jobs and economic activity.

The IPPC report on the melting ice caps makes for terrifying reading

Earlier this year, the Intergovernmental Panel on Climate Change (IPCC) – the UN body responsible for communicating the science of climate breakdown – released its long-awaited Special Report on the Ocean and Cryosphere in a Changing Climate.

Based on almost 7,000 peer-reviewed research articles, the report is a cutting-edge crash course in how human-caused climate breakdown is changing our ice and oceans and what it means for humanity and the living planet. In a nutshell, the news isn’t good.

Cryosphere in decline

Most of us rarely come into contact with the cryosphere, but it is a critical part of our climate system. The term refers to the frozen parts of our planet – the great ice sheets of Greenland and Antarctica, the icebergs that break off and drift in the oceans, the glaciers on our high mountain ranges, our winter snow, the ice on lakes and the polar oceans, and the frozen ground in much of the Arctic landscape called permafrost.

The cryosphere is shrinking. Snow cover is reducing, glaciers and ice sheets are melting and permafrost is thawing. We’ve known this for most of my 25-year career, but the report highlights that melting is accelerating, with potentially disastrous consequences for humanity and marine and high mountain ecosystems.

At the moment, we’re on track to lose more than half of all the permafrost by the end of the century. Thousands of roads and buildings sit on this frozen soil – and their foundations are slowly transitioning to mud. Permafrost also stores almost twice the amount of carbon as is present in the atmosphere. While increased plant growth may be able to offset some of the release of carbon from newly thawed soils, much will be released to the atmosphere, significantly accelerating the pace of global heating.

Sea ice is declining rapidly, and an ice-free Arctic ocean will become a regular summer occurrence as things stand. Indigenous peoples who live in the Arctic are already having to change how they hunt and travel, and some coastal communities are already planning for relocation. Populations of seals, walruses, polar bears, whales and other mammals and sea birds who depend on the ice may crash if sea ice is regularly absent. And as water in its bright-white solid form is much more effective at reflecting heat from the sun, its rapid loss is also accelerating global heating.

Glaciers are also melting. If emissions continue on their current trajectory, smaller glaciers will shrink by more than 80 per cent by the end of the century. This retreat will place increasing strain on the hundreds of millions of people globally who rely on glaciers for water, agriculture, and power. Dangerous landslides, avalanches, rockfalls and floods will become increasingly normal in mountain areas.


Rising oceans, rising problems

All this melting ice means that sea levels are rising. While seas rose globally by around 15cm during the 20th century, they’re now rising more than twice as fast –- and this rate is accelerating.

Thanks to research from myself and others, we now better understand how Antarctica and Greenland’s ice sheets interact with the oceans. As a result, the latest report has upgraded its long-term estimates for how much sea level is expected to rise. Uncertainties still remain, but we’re headed for a rise of between 60 and 110cm by 2100.

Of course, sea level isn’t static. Intense rainfall and cyclones – themselves exacerbated by climate breakdown – can cause water to surge metres above the normal level. The IPCC’s report is very clear: these extreme storm surges we used to expect once per century will now be expected every year by mid-century. In addition to rapidly curbing emissions, we must invest millions to protect at-risk coastal and low-lying areas from flooding and loss of life.

Ocean ecosystems

Up to now, the ocean has taken up more than 90 per cent of the excess heat in the global climate system. Warming to date has already reduced the mixing between water layers and, as a consequence, has reduced the supply of oxygen and nutrients for marine life. By 2100 the ocean will take up five to seven times more heat than it has done in the past 50 years if we don’t change our emissions trajectory. Marine heatwaves are also projected to be more intense, last longer and occur 50 times more often. To top it off, the ocean is becoming more acidic as it continues to absorb a proportion of the carbon dioxide we emit.

Collectively, these pressures place marine life across the globe under unprecedented threat. Some species may move to new waters, but others less able to adapt will decline or even die out. This could cause major problems for communities that depend on local seafood. As it stands, coral reefs – beautiful ecosystems that support thousands of species – will be nearly totally wiped out by the end of the century.

Between the lines

While the document makes some striking statements, it is actually relatively conservative with its conclusions – perhaps because it had to be approved by the 195 nations that ratify the IPCC’s reports. Right now, I would expect that sea level rise and ice melt will occur faster than the report predicts. Ten years ago, I might have said the opposite. But the latest science is painting an increasingly grave picture for the future of our oceans and cryosphere – particularly if we carry on with “business as usual”.

The difference between 1.5°C and 2°C of heating is especially important for the icy poles, which warm much faster than the global average. At 1.5°C of warming, the probability of an ice-free September in the Arctic ocean is one in 100. But at 2°C, we’d expect to see this happening about one-third of the time. Rising sea levels, ocean warming and acidification, melting glaciers, and permafrost also will also happen faster – and with it, the risks to humanity and the living planet increase. It’s up to us and the leaders we choose to stem the rising tide of climate and ecological breakdown.
