Russia: autocratic rule continues with the loss of Navalny

 

Alexei Navalny had a vision of a democratic Russia. That terrified Vladimir Putin to the core

Alexei Navalny was a giant figure in Russian politics. No other individual rivalled the threat he posed to the Putin regime. His death in an Arctic labour camp is a blow to all those who dreamed he might emerge as the leader of a future democratic Russia.

What made Navalny so important was his decision to become an anti-corruption crusader in 2008. Using shareholder activism and his popular blog, he shone a spotlight on the corruption schemes that enabled officials to steal billions from state-run corporations.

His breakthrough came in 2011, when he proposed the strategy of voting for any party but President Vladimir Putin’s “party of crooks and thieves” in the Duma (parliament) elections. Faced with a collapse of support, the regime resorted to widespread election fraud. The result was months of pro-democracy protests.

Putin regained control through a mix of concessions and repression, but the crisis signalled Navalny’s emergence as the dominant figure in Russia’s democratic movement.

Despite being convicted on trumped-up embezzlement charges, he was allowed to run in Moscow’s mayoral elections in 2013. In a clearly unfair contest, which included police harassment and hostile media coverage, he won 27% of the vote.

Perseverance in the face of worsening attacks

The authorities learned from this mistake. Never again would Navalny be allowed to compete in elections. What the Kremlin failed to stop was his creation of a national movement around the Foundation for the Struggle Against Corruption (FBK), which he had founded in 2011 with a team of brilliant young activists.

During the ensuing decade, FBK transformed our understanding of the nature of Putin’s kleptocracy. Its open-source investigations shattered the reputations of numerous regime officials, security functionaries and regime propagandists.

One of the most important was a 2017 exposé of the network of charities that funded the palaces and yachts of then-premier Dmitry Medvedev. Viewed 46 million times on YouTube, it triggered protests across Russia.

No less significant was Navalny’s contribution to the methods of pro-democracy activism. To exploit the regime’s dependence on heavily manipulated elections, he developed a strategy called “intelligent voting”. The basic idea was to encourage people to vote for the candidates who had the best chance of defeating Putin’s United Russia party. The result was a series of setbacks for United Russia in 2019 regional elections.

One measure of Navalny’s impact was the intensifying repression directed against him. As prosecutors tried to paralyse him with a series of implausible criminal cases, they also pursued his family. His younger brother Oleg served three and a half years in a labour camp on bogus charges.

This judicial persecution was compounded by the violence of the regime’s proxies. Two months after exposing Medvedev’s corruption, Navalny was nearly blinded by a Kremlin-backed gang of vigilantes, who sprayed his face with a noxious blend of chemicals.

More serious was the deployment of a death squad from Russia’s Federal Security Service (FSB), which had kept Navalny under surveillance since 2017. The use of the nerve agent Novichok to poison Navalny during a trip to the Siberian city of Tomsk in August 2020 was clearly intended to end his challenge to Putin’s rule.

Instead it precipitated the “Navalny crisis”, a succession of events that shook the regime’s foundations. The story of Navalny’s survival – and confirmation that he had been poisoned with Novichok – focused international attention on the Putin regime’s criminality.

Any lingering doubts about state involvement in his poisoning were dispelled by Navalny’s collaboration with Bellingcat, an investigative journalism organisation, to identify the suspects and deceive one of them into revealing how they poisoned him.

The damage was magnified by Navalny’s decision to confront Putin’s personal corruption. In a powerful two-hour documentary film, A Palace for Putin, Navalny chronicled the obsessive greed that had transformed an obscure KGB officer into one of the world’s most notorious kleptocrats.

With over 129 million views on YouTube alone, the film shattered the dictator’s carefully constructed image as the incarnation of traditional virtues.

‘We will fill up the jails and police vans’

It is difficult to exaggerate the impact of the “Navalny crisis” on Putin, a dictator terrified of the prospect of popular revolution. No longer was he courted by Western leaders. US President Joe Biden began his term in office in 2021 by endorsing an interviewer’s description of Putin as a “killer”.

To contain the domestic fallout, Putin unleashed a crackdown that began with Navalny’s 2021 arrest on his return to Moscow from Germany, where had been recovering from the Novichok poisoning. On the international stage, Putin secured a summit with Biden by staging a massive deployment of military force on the Ukrainian border, a rehearsal for the following year’s invasion.

The Kremlin’s trolling factories also tried to destroy Navalny’s reputation with a smear campaign. Within weeks of Navalny’s imprisonment, Amnesty International rescinded his status as a “prisoner of conscience” on the basis of allegations about hate speech. The evidence was some ugly statements made by Navalny as an inexperienced politician in the mid-2000s, when he was trying to build an anti-Putin alliance of democrats and nationalists.

What his detractors ignored was Navalny’s own evolution into a critic of ethnonationalist prejudices. In a speech to a nationalist rally in 2011, he had challenged his listeners to empathise with people in the Muslim-majority republics of Russia’s northern Caucasus region.

This divergence from the nationalist mainstream was accentuated by Putin’s conflict with Ukraine. After the invasion of Crimea in March 2014, Navalny denounced the “imperialist annexation” as a cynical effort to distract the masses from corruption.

Eight years later, while languishing in prison, he condemned Putin’s full-scale invasion of Ukraine, exhorting his compatriots to take to the streets, saying:

If, to prevent war, we need to fill up the jails and police vans, we will fill up the jails and police vans.

Later that year, he argued a post-Putin Russia needed an end to the concentration of power in the Kremlin and the creation of a parliamentary republic as “the only way to stop the endless cycle of imperial authoritarianism”.

Navalny’s tragedy is that he never had a chance to convert the moral authority he amassed during years as a dissident into political power. Like Charles de Gaulle in France and Nelson Mandela in South Africa, he might have become a redemptive leader, leading his people from war and tyranny to the promised land of a freer society.

Instead, he has left his compatriots the example of a brave, principled and thoughtful man, who sacrificed his life for the cause of democracy and peace. That is his enduring legacy. The Conversation

The risk of ocean change and climate impact

Atlantic Ocean is headed for a tipping point − once melting glaciers shut down the Gulf Stream, we would see extreme climate change within decades, study shows

Superstorms, abrupt climate shifts and New York City frozen in ice. That’s how the blockbuster Hollywood movie “The Day After Tomorrow” depicted an abrupt shutdown of the Atlantic Ocean’s circulation and the catastrophic consequences.

While Hollywood’s vision was over the top, the 2004 movie raised a serious question: If global warming shuts down the Atlantic Meridional Overturning Circulation, which is crucial for carrying heat from the tropics to the northern latitudes, how abrupt and severe would the climate changes be?

Twenty years after the movie’s release, we know a lot more about the Atlantic Ocean’s circulation. Instruments deployed in the ocean starting in 2004 show that the Atlantic Ocean circulation has observably slowed over the past two decades, possibly to its weakest state in almost a millennium. Studies also suggest that the circulation has reached a dangerous tipping point in the past that sent it into a precipitous, unstoppable decline, and that it could hit that tipping point again as the planet warms and glaciers and ice sheets melt.

In a new study using the latest generation of Earth’s climate models, we simulated the flow of fresh water until the ocean circulation reached that tipping point.

The results showed that the circulation could fully shut down within a century of hitting the tipping point, and that it’s headed in that direction. If that happened, average temperatures would drop by several degrees in North America, parts of Asia and Europe, and people would see severe and cascading consequences around the world.

We also discovered a physics-based early warning signal that can alert the world when the Atlantic Ocean circulation is nearing its tipping point.

The ocean’s conveyor belt

Ocean currents are driven by winds, tides and water density differences.

In the Atlantic Ocean circulation, the relatively warm and salty surface water near the equator flows toward Greenland. During its journey it crosses the Caribbean Sea, loops up into the Gulf of Mexico, and then flows along the U.S. East Coast before crossing the Atlantic.

This current, also known as the Gulf Stream, brings heat to Europe. As it flows northward and cools, the water mass becomes heavier. By the time it reaches Greenland, it starts to sink and flow southward. The sinking of water near Greenland pulls water from elsewhere in the Atlantic Ocean and the cycle repeats, like a conveyor belt.

Too much fresh water from melting glaciers and the Greenland ice sheet can dilute the saltiness of the water, preventing it from sinking, and weaken this ocean conveyor belt. A weaker conveyor belt transports less heat northward and also enables less heavy water to reach Greenland, which further weakens the conveyor belt’s strength. Once it reaches the tipping point, it shuts down quickly.

What happens to the climate at the tipping point?

The existence of a tipping point was first noticed in an overly simplified model of the Atlantic Ocean circulation in the early 1960s. Today’s more detailed climate models indicate a continued slowing of the conveyor belt’s strength under climate change. However, an abrupt shutdown of the Atlantic Ocean circulation appeared to be absent in these climate models.

How the ocean conveyor belt works.

This is where our study comes in. We performed an experiment with a detailed climate model to find the tipping point for an abrupt shutdown by slowly increasing the input of fresh water.

We found that once it reaches the tipping point, the conveyor belt shuts down within 100 years. The heat transport toward the north is strongly reduced, leading to abrupt climate shifts.

The result: Dangerous cold in the North

Regions that are influenced by the Gulf Stream receive substantially less heat when the circulation stops. This cools the North American and European continents by a few degrees.

The European climate is much more influenced by the Gulf Stream than other regions. In our experiment, that meant parts of the continent changed at more than 5 degrees Fahrenheit (3 degrees Celsius) per decade – far faster than today’s global warming of about 0.36 F (0.2 C) per decade. We found that parts of Norway would experience temperature drops of more than 36 F (20 C). On the other hand, regions in the Southern Hemisphere would warm by a few degrees.

These temperature changes develop over about 100 years. That might seem like a long time, but on typical climate time scales, it is abrupt.

The conveyor belt shutting down would also affect sea level and precipitation patterns, which can push other ecosystems closer to their tipping points. For example, the Amazon rainforest is vulnerable to declining precipitation. If its forest ecosystem turned to grassland, the transition would release carbon to the atmosphere and result in the loss of a valuable carbon sink, further accelerating climate change.

The Atlantic circulation has slowed significantly in the distant past. During glacial periods when ice sheets that covered large parts of the planet were melting, the influx of fresh water slowed the Atlantic circulation, triggering huge climate fluctuations.

So, when will we see this tipping point?

The big question – when will the Atlantic circulation reach a tipping point – remains unanswered. Observations don’t go back far enough to provide a clear result. While a recent study suggested that the conveyor belt is rapidly approaching its tipping point, possibly within a few years, these statistical analyses made several assumptions that give rise to uncertainty.

Instead, we were able to develop a physics-based and observable early warning signal involving the salinity transport at the southern boundary of the Atlantic Ocean. Once a threshold is reached, the tipping point is likely to follow in one to four decades.

The climate impacts from our study underline the severity of such an abrupt conveyor belt collapse. The temperature, sea level and precipitation changes will severely affect society, and the climate shifts are unstoppable on human time scales.

It might seem counterintuitive to worry about extreme cold as the planet warms, but if the main Atlantic Ocean circulation shuts down from too much meltwater pouring in, that’s the risk ahead.

Has the world crossed the 1.5C warming threshold already ?

                                                                                                      Shutterstock
Earlier this week, the media carried a series of articles suggesting that the threshold of limiting increased global temperature to 1.5C had already been crossed. The articles are based on new research on ocean temperatures that surmised that "hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 +/- 0.1C above pre-industrial levels by 2020".  In short, this research and possible discovery means that the temperature is 0.5C higher than IPCC estimates with 20  C projected by the late 2020s, nearly two decades earlier than expected.

A team led by Professor Malcolm McCulloch from the University of Western Australia studied 300 years of records preserved in the skeletons of long-lived sea sponges from the Eastern Carribean. Of particular importance the sclerosponge thermometry shows that global warming has already exceeded 1.5C. The focus of the research was changes in the amount of a chemical known as 'strontium' in the sponges skeletons. The changes in the amount of strontium reflects variations in seawater temperatures over the sponges' life.

The conclusion reached is that the Earth may already have reached at least 1.7C warming since pre-industrial times, well above the Paris Climate target of 1.5C. The opportunity for controlling climate change at the first milestone has already been lost.
