Emissions have plunged 75% since communist times in the birthplace of big oil – but for some the transition has been brutal

Once the frozen fields outside Bucharest have thawed, workers will assemble the largest solar farm in Europe: one million photovoltaic panels backed by batteries to power homes after sunset. But the 760MW project in southern Romania will not hold the title for long. In the north-west, authorities have approved a bigger plant that will boast a capacity of 1GW.

The sun-lit plots of silicon and glass will join a slew of projects that have rendered the Romanian economy unrecognisable from its polluted state when communism ended. They include an onshore windfarm near the Black Sea that for several years was Europe’s biggest, a nuclear power plant by the Danube whose lifetime is being extended by 30 years, and a fast-spreading patchwork of solar panels topping homes and shops across the country.

The groundbreaking singer, actor and athlete became a victim of McCarthyism and saw his shining career destroyed and his legacy tarnished

In August 1972, the front page of the New York Times arts section published a story titled, Time to Break the Silence on Paul Robeson? The legendary bass-baritone spent the first half of the 20th century as one of the greatest talents the US had ever produced, and its second, both in life and in death as an outcast, the greatest casualty of the second Red Scare period to which today’s current attacks on liberal and progressive politics draw comparison.

This week marks 50 years since Robeson’s death and the silence remains. His erasure from the lineage over the decades shows that what Robeson’s political opponents did not take from him, the years have most certainly. Robeson’s decoupling from the story of African American culture has been so complete that in the half-century since his death, even generations of Black Americans have never heard of him.

Soviet invasions of allies helped destroy the Warsaw Pact – Trump’s dangerous rhetoric risks repeating the mistake inside Nato

Donald Trump’s echoing of Russia’s talking points in its war against Ukraine has long been a cause for alarm and dismay in the west.

Now an even more disturbing Kremlin precedent dating from the cold war is being evoked by the US president’s fixation on taking over Greenland – that of carrying out attacks on military allies.

Video shows Gen Xu Qinxian explaining why he refused to deploy troops to crush 1989 student-led demonstrations

Rare footage of a People’s Liberation Army (PLA) general who defied orders to lead his troops into Tiananmen Square and crush the 1989 student protesters has been leaked online, offering a highly unusual glimpse into the upper echelons of the military at one of the most fraught moments in modern Chinese history.

General Xu Qinxian’s refusal to take his troops from the PLA’s prestigious 38th Group Army, a unit based on the outskirts of Beijing, into the capital has been the stuff of Tiananmen lore for decades.

As the first part of his acclaimed Blinding trilogy is released in the UK, the novelist talks about communism, Vladimir Nabokov – and those Nobel rumours

In 2014, when he was travelling around the US on a book tour, Mircea Cărtărescu was able to fulfil the dream of a lifetime: a tour of Vladimir Nabokov’s butterfly collection. Cărtărescu is a great admirer of the Russian-American author, and shares with him a literary career that bridges the western and eastern cultural spheres – as well as a history of being mooted as the next Nobel literature laureate but never having won it.

Above all, the Romanian poet and novelist shares Nabokov’s fascination with butterflies. As a child, he harboured dreams of becoming a lepidopterist. On a visit to Harvard, Cărtărescu was allowed access to Nabokov’s former office and marvelled at specimens the St Petersburg-born author had collected. “His most important scientific work was about butterflies’ sexual organs, and I saw these very tiny vials with them in,” he whispers in awe. “It’s like an image from a poem or a story. It was absolutely fantastic.”
