The Environment In 2050: Flooded Cities, Forced Migration – And The Amazon Turning To Savannah

The Guardian

Unless we focus on shared solutions, violent storms and devastating blazes could be the least of the world’s troubles. Civilisation itself will be at risk

"Good morning. Here is the shipping forecast for midday, 21 June, 2050. Seas will be rough, with violent storms and visibility ranging from poor to very poor for the next 24 hours. The outlook for tomorrow is less fair."
All being well, this could be a weather bulletin released by the Met Office and broadcast by the BBC in the middle of this century. Destructive gales may not sound like good news, but they will be among the least of the world’s problems in the coming era of peak climate turbulence. With social collapse a very real threat in the next 30 years, it will be an achievement in 2050 if there are still institutions to make weather predictions, radio transmitters to share them and seafarers willing to listen to the archaic content.
I write this imaginary forecast with an apology to Tim Radford, the former Guardian science editor, who used the same device in 2004 to open a remarkably prescient prediction on the likely impacts of global warming on the world in 2020.
Journalists generally hate to go on record about the future. We are trained to report on the very recent past, not gaze into crystal balls. On those occasions when we have to venture ahead of the present, most of us play it safe by avoiding dates that could prove us wrong, or quoting others.
Radford allowed himself no such safe distance or equivocation in 2004, which we should remember as a horribly happy year for climate deniers. George W Bush was in the White House, the Kyoto protocol had been recently zombified by the US Congress, the world was distracted by the Iraq war and fossil fuel companies and oil tycoons were pumping millions of dollars into misleading ads and dubious research that aimed to sow doubt about science.
Radford looked forward to a point when global warming was no longer so easy to ignore. Applying his expert knowledge of the best science available at the time, he predicted 2020 would be the year when the planet started to feel the heat as something real and urgent.
“We’re still waiting for the Earth to start simmering,” he wrote back in that climate-comfortable summer of 2004. “But by 2020 the bubbles will be appearing.”
The heat of the climate movement is certainly less latent. In the past year, the world has seen Greta Thunberg’s solo school strikes morph into a global movement of more than six million demonstrators; Extinction Rebellion activists have seized bridges and blocked roads in capital cities; the world has heard ever more alarming warnings from UN scientists, David Attenborough and the UN envoy for climate action, Mark Carney; dozens of national parliaments and city councils have declared climate emergencies; and the issue has risen further to the fore in the current UK general election than any before it. With only weeks to go until 2020, the bubbles of climate anxiety are massing near the surface.
Radford’s most precise predictions relate to the science. Writing after the record-breaking UK heat of 2003, he warned such scorching temperatures would become the norm. “Expect summer 2020 to be every bit as oppressive.” How right he was. Since then, the world has sweltered through the 10 hottest years in history. The UK registered a new high of 38.7C this July, which was the planet’s warmest month since measurements began.

He also correctly anticipated how much more hostile this would make the climate – with increasingly ferocious storms (for the first time on record, there have been category 5 hurricanes, such as Dorian and Harvey, for four years in a row), intensifying forest fires (consider the devastating blazes in Siberia and the Amazon this year, or California and Lapland in 2018) and massive bleaching of coral reefs (which is happening with growing frequency across most of the world). All of this has come to pass, as have Radford’s specific predictions of worsening floods in Bangladesh, desperate droughts in southern Africa, food shortages in the Sahel and the opening up of the northwest passage due to shrinking sea ice (the huge cruise liner, Crystal Serenity, is among the many ships that have sailed through the Bering Strait in recent years – a route that was once deemed impossible by even the most intrepid explorers).
A couple of his predictions were slightly premature (the snows on Kilimanjaro and Mt Kenya have not yet disappeared, though a recent study said they will be gone before future generations get a chance to see them), but overall, Radford’s vision of the world in 2020 was remarkably accurate, which is important because it confirms climate science was reliable even in 2004. It is even more precise today, which is good news in terms of anticipating the risks, but deeply alarming when we consider just how nasty scientists expect the climate to become in our lifetime. Unless emissions are slashed over the next decade, a swarm of wicked problems are heading our way.
How wicked? Well, following Radford’s example, let us consider what the world will look like in 2050 if humanity continues to burn oil, gas, coal and forests at the current rate.
The difference will be visible from space. By the middle of the 21st century, the globe has changed markedly from the blue marble that humanity first saw in wondrous colour in 1972. The white northern ice-cap vanishes completely each summer, while the southern pole will shrink beyond recognition. The lush green rainforests of the Amazon, Congo and Papua New Guinea are smaller and quite possibly enveloped in smoke. From the subtropics to the mid-latitudes, a grimy-white band of deserts has formed a thickening ring around the northern hemisphere.
Coastlines are being reshaped by rising sea levels. Just over 30cm at this stage – well short of the 2 metres that could hit in 2100 – but still enough to swamp unprotected stretches of land from Miami and Guangdong to Lincolnshire and Alexandria. High tides and storm surges periodically blur the boundaries between land and sea, making the roads of megacities resemble the canals of Venice with increasing frequency.
On the ground, rising temperatures are changing the world in ways that can no longer be explained only by physics and chemistry. The increasingly hostile weather is straining social relations and disrupting economics, politics and mental health.
Generation Greta is middle aged. Their teenage fears of the complete extinction of the human race have not yet come to pass, but the risk of a breakdown of civilisation is higher than at any previous time in history – and rising steadily. They live with a level of anxiety their grandparents could have barely imagined.

The world in 2050 is more hostile and less fertile, more crowded and less diverse. Compared with 2019, there are more trees, but fewer forests, more concrete, but less stability. The rich have retreated into air-conditioned sanctums behind ever higher walls. The poor – and what is left of other species – is left exposed to the ever harsher elements. Everyone is affected by rising prices, conflict, stress and depression.
This is a doorway into peak climate turbulence. Global heating passed the 1.5C mark a couple of years earlier and is now accelerating towards 3C, or possibly even 4C, by the end of the century. It feels as if the dial on a cooker has been turned from nine o’clock to midnight. Los Angeles, Sydney, Madrid, Lisbon and possibly even Paris endure new highs in excess of 50C. London’s climate resembles Barcelona’s 30 years earlier. Across the world, droughts intensify and extreme heat becomes a fact of life for 1.6bn city dwellers, eight times more than in 2019. For a while, marathons, World Cups and Olympics were moved to the winter to avoid the furnace-like heat in many cities. Now they are not held at all. It is impossible to justify the emissions and the world is no longer in the mood for games.
Extreme weather is the overriding concern of all but a tiny elite. It wreaks havoc everywhere, but the greatest misery is felt in poorer countries. Dhaka, Dar es Salaam and other coastal cities are hit almost every year by storm surges and other extreme sea-level incidents that used to occur only once a century. Following the lead set by Jakarta, several capitals have relocated to less-exposed regions. But floods, heatwaves, droughts and fires are increasingly catastrophic. Healthcare systems are struggling to cope. The economic costs cripple poorly prepared financial institutions. Insurance companies refuse to provide cover for natural disasters. Insecurity and desperation sweep through populations. Governments struggle to cope.
“By 2050, if we fail to act, many of the most damaging, extreme weather events we have seen in recent years will become commonplace,” warns Michael Mann, the director of the Earth System Science Center at Pennsylvania State University. “In a world where we see continual weather disasters day after day (which is what we’ll have in the absence of concerted action), our societal infrastructure may well fail … We won’t see the extinction of our species, but we could well see societal collapse.”

Adding to the anxiety is the erratic temperature of the planet. Instead of rising smoothly it jolts upwards, because tipping points – once the stuff of scientific nightmares – are reached one after another: methane release from permafrost; a die-off of the tiny marine organisms that sequestered billions of tonnes of carbon; the dessication of tropical forests. People have come to realise how interconnected the world’s natural life-support systems are. As one falls, another is triggered – like dominos or the old board game, Mouse Trap. In some cases, they amplify one another. More heat means more forest fires, which dries out more trees, which burn more easily, which releases more carbon, which pushes global temperatures higher, which melts more ice, which exposes more of the Earth to sunlight, which warms the poles, which lowers the temperature gradient with the equator, which slows ocean currents and weather systems, which results in more extreme storms and longer droughts. It is also now clear that positive climate feedbacks are not limited to physics, but stretch to economics, politics and psychology. The Amazon is turning into a savannah because the loss of forest is weakening rainfall, which makes harvests lower, which gives farmers an economic motivation to clear more land to make up for lost production, which means more fires and less rain.
On our current course, carbon concentrations in the atmosphere will pass 550 parts per million by midcentury, up from around 400ppm today. Katharine Hayhoe, an atmospheric scientist and director of the Climate Science Center at Texas Tech University, explains how this stacks the odds in favour of disaster.
“By 2050, we’d be seeing events that are far more frequent and/or far stronger than we humans have ever experienced before, are occurring both simultaneously and in sequence.”
Her greatest concern is that food production and water supply systems could buckle under the strain, with dire humanitarian consequences in areas that are already vulnerable.
Generation Greta live with a level of anxiety their grandparents could barely have imagined
Hunger will rise, perhaps calamitously. The United Nations’ International Panel on Climate Change expects food production to decline by 2% to 6% in each of the coming decades because of land-degradation, droughts, floods and sea-level rise. The timing could not be worse. By 2050, the global population is projected to rise to 9.7 billion, which is more than two billion more people to feed than today.
When crops fail and starvation threatens, people are forced to fight or flee. Between 50 and 700 million people will be driven from their homes by midcentury as a result of soil degradation alone, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) estimated last year. Fires, floods and droughts will prompt many others to migrate within and across borders. So will the decline of mountain ice, which is a source of meltwater for a quarter of the world’s population. The poorest will be worst affected, though they have the least responsibility for the climate crisis. For the US author and environmentalist, Bill McKibben, this injustice will make the greatest impact in 2050.
“Forcing people to move from their homes by the hundreds of millions may do the most to disrupt the world. And, of course, it’s a deep tragedy, because these are precisely the people who have done the least to cause the problem,” he says.
In 2050, climate apartheid goes hand-in-hand with increasingly authoritarian politics. Three decades earlier, worried electorates voted in a generation of populist “strongmen” in the hope they could turn back the clock to a more stable world. Instead, their nationalism made a global solution even harder to achieve. They preferred to focus on the immigration consequences of global heating rather than the carbon-capital causes. When voters realised their mistake, it was too late. The thugocracy refused to give up power. They no longer deny the climate crisis; they use it to justify ever-more repressive measures and ever-wilder efforts to find a technological fix. In the past 20 years, nations have tried volcano mimicking, cloud brightening, albedo modification and carbon dioxide removal. Most were expensive and ineffective. Some made weather circulation even less reliable. Powerful countries now threaten rivals not just with nuclear weapons, but with geo-engineering threats to block sunlight or disrupt rainfall patterns.
This is not an inevitable future. Unlike Radford’s prediction for 2020, this vision of 2050 factors in human behaviour, which is more volatile and less predictable than the laws of thermodynamics. Many of the horrors above are already baked into the climate, but our response to them – and each other – is not predetermined. When it comes to the science, the dangers can be substantially reduced if humanity shifts decisively away from business-as-usual behaviour over the next decade. When it comes to the psychology and politics, we can make our situation better immediately if we focus on hope in shared solutions, rather than fears of what we will lose as individuals.
That means putting faith in institutions, warning one another about risks, and treasuring shared eccentricities and traditions – a bit like the shipping forecast.
A storm is certainly brewing. The science is clear on that. The question now is how we face it.

(AU) Dirty Power: An Australian Political Investigation

Greenpeace

The coal industry has infiltrated Australia's federal government through a secretive network of ties, working to influence Australia’s political decisions at the highest level: right up to the office of the Prime Minister, Scott Morrison


 Dirty Power: Big Coal's network of influence over the coalition government

We’ve uncovered the web of connections between the world’s biggest coal giants, industry groups, lobbyists and powerful media organisations that serves to halt action on climate change and stall the transition to clean energy.

Why is this so horrifying?
Coal is the number one cause of climate damage. It causes more frequent and intense natural disasters like bushfires while also polluting our water and air.
By pandering to the interests of the coal industry, the Coalition Government is putting dirty profits ahead of the health and wellbeing of Australians who want our nation to run on clean energy.
From furthering the fossil-fuelled agenda of current Prime Minister Scott Morrison, to helping to bring about the swift downfall of former Prime Minister Malcolm Turnbull: the coal industry has infiltrated the Australian Government at the highest level.
This report is based on interviews with dozens of political operatives, current and former staffers, executives of external lobby firms, and resources sector analysts; previously hidden details about the identity and background of federal ministers’ parliamentary staff; and publicly available information about listed companies and their operatives.
We worked with experienced investigative journalist, Michael West, to expose the web of ties between the coal industry and federal government via industry groups, lobbyists and media.
