Ten years ago, the Japanese nuclear power station at Fukushima was devastated by a tsunami. Its baleful ruins remain today.
Almost a decade ago, on 11 March 2011, a massive earthquake created a 14 metre-high tsunami wave which destroyed the reactors of a Japanese nuclear power station at the town of Fukushima. Ten years on, the clean-up has barely begun.
Large areas of farmland and towns near the plant are still highly contaminated, too dangerous to inhabit. Constant vigilance is needed to prevent the stricken reactors causing further danger. It will be at least another 20 years before they can be made safe.
At first the gravity of the accident was overshadowed by the other damage the tsunami had caused, particularly the loss of nearly 20,000 people from communities along the coast who were swept to their deaths as their towns and villages were ruined.
Heart-rending scenes filled television screens across the world for days as rescue teams hunted for survivors and parents separated from their children searched evacuation centres.
As with the Chernobyl accident in 1986, the world’s worst nuclear disaster, the true extent of the damage to Fukushima’s six reactors was not fully grasped. When it was, the authorities tried to play it down.
Because the wave had overwhelmed the cooling system three reactors had suffered a meltdown, but for some this was not public knowledge. The damage had meant that overheated uranium fuel had melted, turning to liquid and dissolving its cladding. The cladding contained zirconium, which reacted with the cooling water to make hydrogen; by 14 March this had caused three explosions at the plant.
Downwind the danger from the radiation spewing from the plant was so great that 164,000 people were evacuated from their homes. Many will never return, because the houses are too contaminated.
In an attempt to get people to return to the villages and towns in the less affected areas the government spent US$28 billion (£20bn) and created 17 million tonnes of nuclear waste. This has proved only partially successful because of widespread mistrust of the government, and measurements by independent groups, including Greenpeace − which show that levels of radiation are well above internationally agreed safe limits for members of the public.
“The government of Japan is on a mission to erase from public memory the triple reactor meltdown and radioactive contamination … they have failed to impose their atomic amnesia on the people of Japan”
But the knock-on effects of the disaster, both in Japan and in the rest of the world, are still being felt. Japan’s nuclear industry shut down its 54 operational reactors, and both the nuclear companies and the government are still trying to persuade local people to allow most of them to reopen.
This year there are 33 reactors that could still be restored to use, but only nine (in five power plants) that are actually operating.
Across the world some countries decided to close down their reactors as soon as possible, and not to build any more. Among them was Germany.
Even in countries like France, where nuclear power dominates the electricity system, there were demands for the country’s reactors to fit far tighter safety measures.
The net effect of the accident has been to turn public opinion against nuclear power in many countries. Even in those still interested in building new stations, the higher safety standards now demanded have made nuclear power more expensive.
Opting for close-down
In Japan itself the Fukushima crisis is far from over. The government is still facing compensation claims from citizens, and the bill for the clean-up keeps mounting.
One of the most critical current problems is the 1.25 million tonnes of cooling water used to prevent the stricken reactors from further meltdown. It is now stored in tanks on site.
In October 2020 the government announced plans to release it into the Pacific Ocean, because it could think of no other way of getting rid of it. This idea has caused outrage among fishermen along the coast, who fear that no one will buy their catch for fear of the radiation.
Longer-term technical problems also remain unresolved. With the reactor cores too dangerous to approach, special robots have been developed to dismantle them. This is perhaps one of the most difficult engineering tasks it is possible to envisage, because intense radioactivity attacks electrical equipment and can destroy the expensive robots.
Forced to return
The government continues to reassure citizens that it has the situation under control, although it expects it will take decades to make the area completely safe.
But there continues to be criticism among environmental groups about the government’s handling of the situation, both at the plant and in the surrounding countryside.
The Greenpeace report details moves to coerce local people into returning to their homes, even though they remain well above international safety levels.
The report said the result of a November 2020 survey showed that in some areas which the government had designated as safe, Greenpeace’s measurements found radiation remains too high for normal life to be considered possible without increased health risks to returning citizens, particularly children and women of child-bearing age.
It says: “One decade after March 2011, we are in the early stages of the impact of this disaster. This is not the official narrative. For the government of Shinzo Abe, in power for most of the last 10 years, and his successor Yoshihide Suga, the communication to the people of Japan and the wider world is that decontamination has been effective, completed and that radiation levels are safe. This is clearly false.
“The government of Japan is on a mission to erase from public memory the triple reactor meltdown and radioactive contamination of a large part of Japan. However, they have failed to impose their atomic amnesia on the people of Japan.”
Greenpeace says this failure is largely due to active citizens and their lawyers holding the Tokyo Electric Power Company to account for the accident and asking for compensation.
It pledges that, together with scientists and various United Nations agencies that monitor the plant, it will ensure that the “ongoing nuclear disaster, its effects and consequences will continue to be better understood and explained in the years and decades ahead.” − Climate News Network

Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming
by Paul Hawken and Tom Steyer
In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. Available On Amazon
Designing Climate Solutions: A Policy Guide for Low-Carbon Energy
by Hal Harvey, Robbie Orvis, Jeffrey Rissman
With the effects of climate change already upon us, the need to cut global greenhouse gas emissions is nothing less than urgent. It’s a daunting challenge, but the technologies and strategies to meet it exist today. A small set of energy policies, designed and implemented well, can put us on the path to a low carbon future. Energy systems are large and complex, so energy policy must be focused and cost-effective. One-size-fits-all approaches simply won’t get the job done. Policymakers need a clear, comprehensive resource that outlines the energy policies that will have the biggest impact on our climate future, and describes how to design these policies well.

This Changes Everything: Capitalism vs. The Climate
by Naomi Klein
In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance to simultaneously reduce gaping inequalities, re-imagine our broken democracies, and rebuild our gutted local economies. She exposes the ideological desperation of the climate-change deniers, the messianic delusions of the would-be geoengineers, and the tragic defeatism of too many mainstream green initiatives. And she demonstrates precisely why the market has not—and cannot—fix the climate crisis but will instead make things worse, with ever more extreme and ecologically damaging extraction methods, accompanied by rampant disaster capitalism.
