A moon “wobble” will contribute to an increase in severe flooding in the mid-2030s, NASA has warned.
The moon’s orbit, which affects the Earth’s tides, has a natural “wobble” every 18.6 years that causes extremely high and low tides.
In a new study, published by Nature Climate Change, NASA’s Sea Level Change Science Team calculated that the next wobble in the mid-2030s will amplify rising sea levels caused by climate change.

Almost all of US mainland coastlines, as well as Hawaii and Guam, are likely to see high-tide flood numbers surge as they come under pressure from the higher seas.
But northern coastlines, including Alaska’s, will be spared for another decade or longer because these land areas are rising due to long-term geological processes, researchers found.

The study is the first to take into account all known oceanic and astronomical causes for floods, NASA said.
High-tide floods, also known as nuisance floods or sunny day floods, occur not because of storm surges from extreme weather or excessive precipitation, but instead when the tide rises into populated areas.

The floods can overwhelm storm drains, close roads and compromise infrastructure over time, according to the National Oceanic and Atmospheric Administration (NOAA).
NASA administrator Bill Nelson said: “Low-lying areas near sea level are increasingly at risk and suffering due to the increased flooding, and it will only get worse.
“The combination of the moon’s gravitational pull, rising sea levels, andclimate change will continue to exacerbate coastal flooding on our coastlines and across the world.”
“It’s the accumulated effect over time that will have an impact,” added Phil Thompson, an assistant professor at the University of Hawaii and the lead author of the new study.

High tide floods are less dramatic and involve less water than hurricane storm surges, so they are often seen as a less pressing problem.
“But if it floods 10 or 15 times a month, a business can’t keep operating with its parking lot underwater,” Mr Thompson said.
“People lose their jobs because they can’t get to work. Seeping cesspools become a public health issue.”
The floods will also occur in clusters, which could last a month or longer at a time depending on the position of the moon, sun, and Earth, NASA said.
As the moon and Earth line up with each other and the sun in specific ways, some city dwellers could see flooding every day or two.
Ben Hamlington, who leads NASA’s Sea Level Change Team, said the study is vital for coastal urban planners, who may tend to focus on preparing for extreme weather events over chronic flooding.
“From a planning perspective, it’s important to know when we’ll see an increase,” Mr Hamlington said.

“Understanding that all your events are clustered in a particular month, or you might have more severe flooding in the second half of a year than the first – that’s useful information.”
The moon is currently in the tide-amplifying part of its 18.6-year wobble, but most US coastlines are yet to see enough sea-level rise to notice the flooding effects.
By the mid-2030s, the next time the wobble enters its tide-amplifying phase, global sea levels will have had another decade to rise due to climate change.
The study projected results out to 2080 by mapping “NOAA’s widely used sea level rise scenarios and flooding thresholds, the number of times those thresholds have been exceeded annually, astronomical cycles, and statistical representations of other processes, such as El Niño events, that are known to affect tides.”
Derek Chauvin – the ex-police officer jailed over the murder of George Floyd – was stabbed 22 times with an “improvised knife” in prison, it has emerged.
The 52-year-old, a former member of the Mexican Mafia, told FBI agents he attacked Chauvin on that date as a symbolic connection to the Black Lives Matter movement.
He also revealed he had been thinking about targeting Chauvin for over a month – and said he would have killed the high-profile inmate had officers not intervened so quickly.

“Life-saving measures” were performed after the stabbing in the prison library, and Chauvin is “expected to survive”.
Turscak has also been charged with three counts of assault and could face an additional 60 years behind bars if convicted. He had been due to complete his current sentence by 2026.
He had led a faction of the Mexican Mafia in Los Angeles during the late 1990s, and went by the nickname “Stranger”.

The former gang member later became an FBI informant and recorded conversations with his associates in the hope of receiving a lighter sentence.
Chauvin had been moved to the jail in Tucson, Arizona last August – and at the time, his lawyer had called for him to be kept away from other inmates for his own protection.

2021: Moment Chauvin was jailed
The disgraced cop was convicted of second-degree murder and violating George Floyd’s civil rights after pressing a knee on his neck for nine-and-a-half minutes outside a store in Minnesota in 2020.
Mr Floyd had been suspected of using a counterfeit $20 (£16) bill, and footage from bystanders captured him telling officers “I can’t breathe”.
His death sparked protests worldwide and a national reckoning with police brutality and racism.
Los Angeles police are hunting a potential serial killer after three homeless people were shot dead in separate incidents.
The murders took place over a few days – between 26 and 29 November – and the city’s mayor warned rough sleepers on Friday: “Try not to be alone tonight.”
CCTV has been released of the suspect, who’s described as male and probably wearing a hoodie; as well as a dark-coloured vehicle he might be using.

LA police chief Michel Moore said a special task force had been set up “to uncover the identity of a potential serial killer preying on the most vulnerable in our community”.
The murders share similarities: all three happened in the early hours and all suspects were homeless and alone.
Mr Moore said all were shot as they were sleeping or preparing to bed down for the night.
The Los Angeles Times named them as Jose Bolanos, 37, Mark Diggs, 62, and a 52-year-old man who’s yet to be named.
Mayor Karen Bass said she had met with the housing department and homeless service and that they are doing “all we can to make shelter and services available”.

“Our message to our unhoused community is clear – try not to be alone tonight,” she said.
The mayor added: “To the many Angelenos who have friends or family who are unhoused, please let them know the danger that exists.”
Republican congressman George Santos has been expelled from the House of Representatives after a report found “overwhelming evidence” he misused campaign donations.
Mr Santos was ousted 311-114 in a bipartisan vote – only the sixth time a member has been kicked out of the House since it was founded in 1789.
Two-thirds of members must support the move – but an excoriating report by the House ethics committee that accused him of breaking federal law appeared to seal his fate.
The 35-year-old led his own defence on the floor of the House and said he would “not stand by quietly”.
Speaking the evening before the vote, he said: “The people of the Third District of New York sent me here. If they want me out, you’re going to have to go silence those people and go take the hard vote.”
Mr Santos argued it would set a precedent that would make expulsions more common.
Three previous cases involved disloyalty to the Union during the American Civil War, the remaining two were after politicians were convicted of federal crimes.
A congressional investigation found he charged his campaign account nearly $4,000 (£3,151) for spa treatments, including Botox.
He also spent more than $4,000 at designer store Hermes and made “smaller purchases” from the OnlyFans site – best known for sexual content.

As the outcome of Friday’s vote became clear, Mr Santos put his coat over his shoulders, shook hands with some members who voted against his expulsion and exited the chamber.
The House Speaker solemnly instructed a clerk to inform New York’s governor that his seat was now vacant.
Mr Santos was in his first term and had been previously feted as an exciting prospect after he flipped a district from the Democrats in November 2022.
But the committee launched a probe in March after reports he lied about having Jewish ancestry and his grandparents fleeing the Nazis, working at elite investment bank Goldman Sachs, and his college degree.
It lasted eight months and found “overwhelming evidence” of law-breaking – and Mr Santos has now admitted making up much of his biography.

The US attorney’s office indicted him in May, accusing him of cheating donors, laundering campaign funds for his own personal use, and lying to Congress.
It alleged he stole donors’ identities and used their credit cards to make tens of thousands in authorised charges.
Mr Santos has pleaded not guilty to the charges and his trial is scheduled for September 2024.
“Mr Santos is not a victim. He is a perpetrator of a massive fraud on his constituents and the American people,” said Susan Wild, the top Democrat on the ethics committee.
The last person to be kicked out of the House was Democrat James Traficant over a criminal corruption conviction in 2002.
New York state governor Kathy Hochul now has 10 days to call a special election for Mr Santos’s seat.
