Parts of China have been hit by “the heaviest rain in 1,000 years” – with footage showing underground train carriages filling with water.
More than 20cm of rain fell on the city of Zhengzhou, Henan province, in a single hour on Tuesday. In the recent European floods, the worst-hit areas of Germany saw 18.2cm over three days.
At least 12 people died in the floods and 100,000 were forced to flee their homes, according to China’s state news agency Xinhua.

“The water reached my chest.
“I was really scared, but the most terrifying thing was not the water, but the increasingly diminishing air supply in the cabin.”

Sky News Asia correspondent Tom Cheshire tweeted: “Very distressing scenes in Zhengzhou right now where there is severe flooding. People trapped in subway – some rescued but other videos appear to show dead bodies.”
Zhengzhou, the capital of Henan, has a population of more than 10 million and is located on the bank of the Yellow River – one of China‘s largest waterways.
Other cities in Henan – including Ruzhou – have also been ravaged by the waters.
The Shaolin Temple in Dengfeng had to close, and an aluminium plant in the city exploded, sending water surging into the facility.
The Longmen Grottoes – a UNESCO World Heritage site featuring buddhas etched into limestone dating back as far as 500 AD – are also threatened by the flooding.

More than 30 reservoirs in Henan have exceeded their warning levels and overnight the rainfall caused a 20-metre breach in the Yihetan dam in the city of Luoyang west of Zhengzhou.
In Zhengzhou, the flood control headquarters said the city’s Guojiazui reservoir had been breached.
From Saturday to Tuesday, 3,535 weather stations in Henan saw rainfall exceeding 5cm, of which 1,614 had levels above 10cm and 151 above 25cm.
Speaking on state television, Chinese President Xi Jinping said: “Flood prevention efforts have become very difficult.”
Flooding is not uncommon in China during the rainy season, but the expansion of cities and conversion of agricultural land into housing has put more people closer to danger.
Forecasters are predicting the downpours to end by Thursday.
In a stark and direct intervention, Martin Griffiths, the former UN humanitarian chief, has described the situation in Gaza as genocide.
The statement, made during an interview I conducted with Griffiths on The World, marks one of the most pointed accusations yet from a figure known to be deeply embedded in the world of international politics and diplomacy.
“I think now we’ve got to the point this is unequivocal. Of course it is genocide. Just as it is weaponising aid.
“We don’t need to look behind ourselves to see that’s the case. That should encourage us even more because we, of course, all doubted whether it would come to that level of definition.
“We all doubted whether famine is actually there. I think starvation is killing people. That’s bad enough. We don’t have to worry about famine, which is obviously there lurking in the shadows.
“Also, genocide… of course that’s what has happened. We only need to look at the statements made. Prime Minister Netanyahuhas the virtue of being very clear about his objectives.”

Ex-Israeli aide dismisses genocide claims
His choice of words is extraordinary – not just for its gravity, but because it’s Griffiths who is saying it.
A veteran diplomat with decades of experience navigating complex international crises, Griffiths is known for his calm and thoughtful demeanour – not for inflammatory language.
For him to use the term “genocide” in a television interview signals a significant shift in how some within the international system are now interpreting events on the ground in Gaza – 20 months since Israel launched its war.

Just weeks earlier, Tom Fletcher, another respected former British ambassador and current UN humanitarian chief, came close to using the phrase during a UN Security Council session.

He said: “What more evidence do you need now? Will you act decisively to prevent genocide and to ensure respect for international humanitarian law? Or will you say instead: ‘we did all we could?'”
Whilst he stopped short, his tone showed a clear change in how leading international figures now view the direction of Israeli military operations in Gaza; staggering civilian deaths, and the statements made by Israeli officials prosecuting this war.

Lawyers representing Israel against accusations brought by South Africa to the International Court of Justice last year – accusing its actions in Gaza of amounting to genocide – called the claims “unfounded”, “absurd” and amounting to “libel”.
They went on to say Israel respected international law and had a right to defend itself.
Now 41.2% of Europe finds itself in some form of drought, according to the latest update from the EU’s European Drought Observatory, which covers 11 to 20 May.
It is most acute in pockets of south-eastern Spain, Cyprus, Greece and Albania, where the strongest “alert” category has been issued, as well as parts of Poland and Ukraine.
But broad stretches of northern and eastern Europe through France, Germany, Poland and Ukraine also drying up, sowing concerns about crop yields.
On Thursday, the UK’s Environment Agency officially declared a drought in North West England after river and reservoir levels were licked away by a dry spring.

Greece tourism is ‘unsustainable’
In Greece, “overtourism” from millions flocking to its beaches adds further pressure to water supplies, said Nikitas Mylopoulos, professor of water resource management at Thessaly University.
“The tourist sector is unsustainable and there is no planning… leading to a tremendous rise in water demand in summer,” he told Sky News.
“The islands have an intense problem of drought and water scarcity.”
Islands like Santorini and Mykonos are now forced to ship in water from Athens or desalination plants to provide for showers and swimming pools. In the past, many residents could make do with local methods like rainwater harvesting.
But agriculture is a far bigger drain on the country’s water, with waste rife and policies lacking, said Prof Mylopoulos.

Wildfire season could be ‘particularly difficult’
This year’s hot and dry conditions are also fuelling the risk of yet another fierce wildfire season in Greece.
Last week civil protection minister Ioannis Kefalogiannis warned of a “particularly difficult” summer.
He said a record 18,000 firefighters have been deployed and the drone fleet almost doubled in a bid to combat fires being fuelled by a hotter climate.
Droughts and their causes are more complicated, but scientists at World Weather Attribution say global warming is exacerbating drought in some parts of the world, including around the Mediterranean.

The International Hydropower Association said drought and intense rain in Europe are pushing power plants to “operate at the limits of their existing equipment”.
Extreme weather costs the EU about €28.3bn (£23.8bn) in lost crops and livestock per year, according to insurance firm Howden.
Hayley Fowler, professor of climate change impacts at Newcastle University, said: “With global warming, we expect more prolonged and intense droughts and heatwaves punctuated by more intense rainfall, possibly causing flash floods.
“In recent years, we have experienced more of these atmospheric blocks, causing record heat and persistent drought, as well as severe flooding in other locations in Europe.
“Recent months have been no different, with prolonged dry conditions and heatwaves in northern Europe and floods in southern Europe.”
At least 117 people have died and others are still missing after heavy flooding in Nigeria, an emergency official said.
Authorities initially said 21 people had died but this figure has today risen significantly.
Media reports quoting local government officials said a dam collapse has worsened the situation.
Ibrahim Hussaini, head of Niger State Emergency Management Agency, said some 3,000 houses were underwater in two communities.
Videos posted on social media show floodwater sweeping through neighbourhoods, with rooftops barely visible above the brown currents. One clip shows a tanker floating through a town.

The chairman of the Mokwa local government area suggested poor infrastructure has worsened the impact of the flooding.
Jibril Muregi has appealed to the government to start “long overdue” construction of waterways in the area under a climate resilience project.

In a similar occurrence last September, torrential rains and a dam collapse in Nigeria’s northeastern Maiduguri caused severe flooding, leaving at least 30 people dead and displacing millions.
Nigeriais prone to flooding during the rainy season, which began in April – and flooding is becoming more common and extreme as the climate warms.
Hotter air is thirstier and can hold more moisture – about 7% more for every 1C warmer – meaning it unleashes heavier flooding when it rains.
Violent rain, which killed hundreds of people in Nigeria during 2022, was made at least 80 times more likely and 20% more intense by climate change, analysis by World Weather Attribution found.
