Storms, floods and wildfires led to more than 43 million displacements of children between 2016 and 2021, UNICEF has said.
The UN agency also warned that 100 million more children could be displaced by extreme weather over the next 30 years.
Weather-related disasters, which are becoming more violent and frequent as greenhouse gases cause the Earth’s atmosphere to heat up, uprooted up to 20,000 children a day in 44 countries over the six-year period, with 95% of those from floods, according to the research.
UNICEF said it had measured the number of child displacements rather than the number of children, as the same person could be displaced more than once.
The true number was also likely to be higher as many cases went undocumented.
China and the Philippines were among the countries most affected because of large child populations that were exposed to extreme weather and because early-warning and evacuation measures had improved recently, meaning better reporting.
Relative to the child population size, those on small island states such as Dominica in the Caribbean and Vanuatu in Oceania were the most affected by storms, while children in Somalia and South Sudan in Africa were most affected by floods.

Flooding accounted for 40.9 million (95%) of child displacements during the period analysed, in part because of effective reporting and evacuation, while droughts caused 1.3 million internal displacements and wildfires triggered 810,000, with more than a third of those in 2020 alone.
Canada, Israel and the US recorded the most wildfire displacements, while Somalia recorded the most from drought.

UNICEF’s executive director Catherine Russell said: “It is terrifying for any child when a ferocious wildfire, storm or flood barrels into their community.
“For those who are forced to flee, the fear and impact can be especially devastating, with worry of whether they will return home, resume school, or be forced to move again.”
In a report called Children Displaced In A Changing Climate, UNICEF said that decisions to move may be abrupt, in the face of immediate danger, or the result of an evacuation where lives are saved but at the cost of having to face other dangers.

Many children at risk of climate displacement were in countries that were already struggling with conflict and poverty and local authorities were often unable to offer enough resources in support.
Using a risk model developed by the Internal Displacement Monitoring Centre, UNICEF said that flooding from rivers had the potential to displace 96 million children over the next 30 years.
Based on other climate data, they said cyclones and storm surges could displace 10.3 million and 7.2 million children respectively over the same period, although the real number would be likely to be much higher as climate change brought more extreme weather more frequently.
“Moving may have saved their lives, but it’s also very disruptive. As the impacts of climate change escalate, so too will climate-driven movement,” Ms Russell said.

Katherine Nightingale, WaterAid’s global director of international affairs, said: “We have the tools and knowledge to respond to this escalating challenge for children, but we are acting far too slowly.
“We need to strengthen efforts to prepare communities, protect children at risk of displacement, and support those already uprooted.
“The climate crisis is a water crisis, with a staggering 90% of all natural disasters water-related and while all of us are feeling the effects, it’s the world’s most vulnerable who suffer the most.
“From flood defences to drought resistance, the solutions exist. But more investment is needed urgently to develop robust and reliable water, sanitation and hygiene systems which serve as a lifeline for communities who must defend themselves against climate uncertainty on a daily basis.”
Britain will be taking “a courageous step at a very difficult time” by officially recognising a Palestinian state, according to the authority’s foreign minister, who told Sky News she believes the announcement – expected in the coming days – will inspire more nations to follow suit.
The Palestinian Authority’s foreign minister, Varsen Aghabekian, told me Britain’s move was “better late than never”, and said “Britain, with its weight, can influence other countries to come forward and recognise, because that is the right thing to do”.
But she also said she is “very angry” with the White House over its “unwavering support” for Israel, and said that Israel’s refusal to pass on tax revenue was pushing Palestinian civil society to the brink of “collapse”.

Could recognition of Palestine change the West Bank?
She told me: “Britain has been supporting the existence and the flourishing of Israel for some time, but I think today Britain is looking at the matter objectively, in terms of the right of people, in terms of complying with international law, and in terms of the future of this area for both the Israelis and Palestinians.”

She rejected the idea that recognising Palestine was a reward for Hamas terrorism, saying that “non-recognition” would also be a “reward to the extremists” and said that “if we wait until Israel decides it wants to go into negotiations with the Palestinians, then it won’t happen”.
Aghabekian told me she expected Gaza to be returned to the Palestinians, but I put it to her that Israeli Prime Minister Benjamin Netanyahu was being empowered by the diplomatic support he receives from America, and in particular, US President Donald Trump.
So is she angry with the White House? “Very angry, because I expect the White House and the United States of America to align with international law, with human rights, with having no double standards.
“This unwavering support for Israel, this blind support, is not only harming the Palestinians but also Israeli society.”

The state of Palestine is already recognised by three-quarters of the United Nations’ members. It comprises two separate territories – the West Bank, including East Jerusalem, and the Gaza Strip. Together, they are officially known as the Occupied Palestinian Territories.
The West Bank has been subject to Israeli military occupation since 1967, while Gaza has been attacked by Israel since the Hamas attacks of 7 October 2023, when nearly 1,200 Israelis were killed and around 250 people were taken hostage.
Since then, more than 65,000 people have been killed in Gaza as Israel has sought to destroy Hamas and recover its hostages. There are 48 hostages still in Gaza, with 20 believed to be alive.
She confirmed to me that Mahmoud Abbas, leader of the Palestinian Authority, which governs the West Bank, “has given guarantees in letters to various leaders around the globe that said Hamas will not be part of the governance of the Gaza Strip” and insisted there was “probably a worldwide consensus” on the topic.

How has UK responded to Israel-Gaza conflict?
But she also insisted it was “not reasonable” to talk of completely erasing Hamas: “Hamas is an ideology, not a building that you bring down. Hamas is in people’s minds; in their heads.
“Those who support Hamas need to see a future, need to see something that is moving on the political level, need to see that there might be a state in which their children and their grandchildren might prosper.
“What people see today, whether they are Hamas supporters or not, they see darkness and they see destruction all over. They see violation of rights. They are helpless and hopeless. People need to see things are moving forward, and once that happens, there will be a shift in the mood, and they will look for a better future.”
But just as the Palestinians prepare to welcome recognition, Aghabekian said the West Bank was facing financial collapse as Israel continues to withhold hundreds of millions of dollars of tax revenue that, under a 30-year-old agreement, it collects on the Palestinian Authority’s behalf.
Israel has retained a proportion of the money since the start of the war in Gaza, but, encouraged by finance minister Bezalel Smotrich, it has recently withheld a much higher amount.
“People have not been paid, civil servants are only receiving small parts of their salaries. We can’t buy medical supplies, equipment, you name it,” said Aghabekian.
“How can a government run a country under such conditions? So yes, we are very worried.”
Passengers have been evacuated from Dublin Airport’s Terminal 2 as a “precautionary measure”.
Flights could be “temporarily impacted”, the airport said in a statement.
It did not give any details about the reason for the evacuation but said “the safety and security of our passengers and staff is our absolute priority”.
“We advise passengers to check with their airline for the latest updates,” the airport added, saying further information would be provided as soon as it is available.
This breaking news story is being updated and more details will be published shortly.
At least 70 people have been killed after a paramilitary drone attack on a mosque in Sudan.
The Sudanese army and aid workers said the paramilitary group Rapid Support Forces (RSF) carried out the attack during Friday prayers in the North Darfur region.
The attack took place in the besieged city of Al Fasher and was said to have completely destroyed the mosque.
With bodies still buried under the rubble, the number of deaths is likely to rise, a worker with the local aid group Emergency Response Rooms said.
The worker spoke anonymously, fearing retaliation from the RSF.
Further details of the attack were difficult to ascertain because it took place in an area where many international and charitable organisations have already pulled out because of the violence.
In a statement, Sudan’s army said it was mourning the victims of the attack.
It said: “Targeting civilians unjustly is the motto of this rebel militia, and it continues to do so in full view of the entire world.”

The Sudan war started in April 2023, when long-simmering tensions between the Sudanese army and the RSF broke out in Khartoum.
The US special envoy to Sudan estimates that 150,000 people have been killed, but the exact figure is unknown. Close to 12 million people have been displaced.
Several mediation attempts have failed to secure a humanitarian access mechanism or any lulls in fighting.
The Resistance Committees in El Fasher, a group of local activists who track abuses, posted a video on Friday claiming to show parts of the mosque reduced to rubble with several scattered bodies.
The Darfur Victims Support Organisation, which monitors abuses against civilians, said the attack happened at a mosque on the Daraga al Oula street at around 5am local time, citing witnesses.
The attack is the latest in a series of heavy clashes in the past week of between the two sides in Al Fasher.
