Massachusetts town grapples with sea rise after sand barrier fails

A $500,000 sand dune collapsed in days after being erected, and residents are looking for help to protect their homes

On the border with New Hampshire and Massachusetts – about 35 miles north of Boston – is Salisbury, a coastal town and popular summer destination for tourists. But for those who live in the town year round, especially those who live on the coastline, life’s not a beach.

Last month, after a series of storms battered the area, local citizens came together to take the necessary steps to protect their homes. Volunteer organization Salisbury Beach Citizens for Change raised more than $500,000 to erect a 15,000-ton sand dune – a formidable barrier that would hopefully protect at least 15 beach houses from destruction.

Australia not prepared for how Antarctic ice changes will hit economy, scientist warns

Exclusive: Prof Matt King says accelerated melting could transform country and affect viability of some agricultural industries

A leading Antarctic scientist has urged the Albanese government to pay closer attention to abrupt changes under way in the southern continent, warning they will affect Australians in ways that are little understood and research into them is drastically underfunded.

The head of the Australian Centre for Excellence in Antarctic Science, Prof Matt King, said he found it embarrassing how little was known about the local and global ramifications of changes including a historic drop in floating sea ice cover, the accelerating melting of giant ice sheets and the slowing of a deep ocean current known as the Southern Ocean overturning circulation.

Half of glaciers will be gone by 2100 even under Paris 1.5C accord, study finds

If global heating continues at current rate of 2.7C, losses will be greater with 68% of glaciers disappearing

Half the planet’s glaciers will have melted by 2100 even if humanity sticks to goals set out in the Paris climate agreement, according to research that finds the scale and impacts of glacial loss are greater than previously thought. At least half of that loss will happen in the next 30 years.

Researchers found 49% of glaciers would disappear under the most optimistic scenario of 1.5C of warming. However, if global heating continued under the current scenario of 2.7C of warming, losses would be more significant, with 68% of glaciers disappearing, according to the paper, published in Science. There would be almost no glaciers left in central Europe, western Canada and the US by the end of the next century if this happened.

Could a digital twin of Tuvalu preserve the island nation before it’s lost to the collapsing climate?

With rising seas expected to submerge the nation by 2100, official says ‘we should always be able to remember Tuvalu as it is, before it disappears’

When Tuvalu vanishes beneath rising seas, its diaspora still want somewhere to call home – and that could be a virtual version of the tiny Pacific nation.

Global heating is threatening to submerge Tuvalu by the end of the century, and its 12,000 inhabitants are considering the future.

Tintagel among castles at risk unless England can hold back the tide

English Heritage identifies six most vulnerable sites as climate change intensifies coastal erosion

The wonderful wildness of the spot, a rocky Cornish headland pounded relentlessly by Atlantic breakers, has inspired poets, artists and dreamers for many a century.

But Tintagel, immortalised in British mythology as the place of King Arthur’s conception, is one of a string of castles at risk of tumbling into the sea as climate change increases the pace of coastal erosion.

The big idea: how can we adapt to life with rising seas?

Traditional defences may fail, and migration won’t be possible for everyone. But we may yet find more creative ways to live


We have passed the point of no return: rising seas will soon directly affect hundreds of millions of people around the planet. They will indirectly affect many millions more as transport connections, water supplies and factories in low-lying areas are lost or have to be relocated. What exactly are we facing? The latest research suggests we are likely to see a rise of a metre by the year 2100. Given how much carbon dioxide is already in the air and oceans, as much as three metres may be baked in over the 200 years or so that follow. And while that might seem like a long way off, coastal groundwater levels will rise much sooner, wrecking infrastructure and causing toxic pollution well before cities such as Miami, New York and San Francisco are permanently inundated.

Where will all those people, warehouses, water treatment plants and rail lines move to, given that the interior of large land masses will have become drier? The forced migration of hundreds of millions of people will undoubtedly lead to serious international conflict over space and basic resources like fresh water. Conflict is another word for war.

‘Blue diplomacy’: France summit puts world’s spotlight on oceans

As One Ocean event in Brest aims to deliver action in areas from pollution to overfishing, activists warn against ‘bluewashing’

Up to 40 world leaders are due to make “ambitious and concrete commitments” towards combating illegal fishing, decarbonising shipping and reducing plastic pollution at what is billed as the first high-level summit dedicated to the ocean.

One Ocean summit, which opens on Wednesday in the French port of Brest, aims to mobilise “unprecedented international political engagement” for a wide range of pressing maritime issues, said its chief organiser, Olivier Poivre d’Arvor.

Scientists watch giant ‘doomsday’ glacier in Antarctica with concern

Cracks and fissures stoke fears of breakup that could lead to half-metre rise in global sea levels – or more

Twenty years ago, an area of ice thought to weigh almost 500bn tonnes dramatically broke off the Antarctic continent and shattered into thousands of icebergs into the Weddell Sea.

The 1,255-sq-mile (3,250-sq-km) Larsen B ice shelf was known to be melting fast but no one had predicted that it would take just one month for the 200-metre-thick behemoth to completely disintegrate.

‘We have to use a boat to commute’: coastal Ghana hit by climate crisis

As the sea claims more of the west African shoreline, those left homeless by floods are losing hope that the government will act

Waves have taken the landscape John Afedzie knew so well. “The waters came closer in the last few months, but now they have destroyed parts of schools and homes. The waves have taken the whole of the village. One needs to use a boat to commute now because of the rising sea levels,” he says.

Afedzie lives in Keta, one of Ghana’s coastal towns, where a month ago high tide brought seawater flooding into 1,027 houses, according to the government, leaving him among about 3,000 people made homeless overnight.

‘Taste this, it’s salty’: how rising seas are ruining the Gambia’s rice farmers

The farmers, mostly women, once grew enough but must now buy imported rice as the climate crisis edges them into poverty

In the sweltering heat of the late-morning west African sun, Aminata Jamba slashes at golden rice stalks with a sickle. “The rice is lovely,” she says, music playing in the background as her son, Sampa, silently harvests the grain. But even if the quality is high, the quantity is not.

While once Jamba could have expected to harvest enough rice to last the whole year, this year she reckons it will last three to four months. After that, she will have to look elsewhere for a way to feed her family and make enough money to live.

Blowing the house down: life on the frontline of extreme weather in the Gambia

A storm took the roof off Binta Bah’s house before torrential rain destroyed her family’s belongings, as poverty combines with the climate crisis to wreak havoc on Africa’s smallest mainland country

The windstorm arrived in Jalambang late in the evening, when Binta Bah and her family were enjoying the evening cool outside. “But when we first heard the wind, the kids started to run and go in the house,” she says.

First they went in one room but the roof – a sheet of corrugated iron fixed only by a timbere pole – flew off. They ran into another but the roof soon went there too.

‘Living from flood to flood’: the crisis of Gambia’s sinking city

As well as floods, sewage and crocodiles, those living in Banjul’s slums face the effects of a climate crisis they did little to cause

Yedel Bah would move home if she could, but she can’t. With no income of her own, four children to feed and a husband who just about manages, her family lives from day to day, and from flood to flood, on the banks of a litter-strewn, stagnant canal.

Every rainy season, the neighbourhood of Tobacco Road in the Gambian capital, Banjul, braces for downpours of such intensity that the canal overflows, spilling its murky, pungent depths into the slum-like homes that run alongside it.

The Guardian view on a Dutch solution: make land out of the sea | Editorial

Faced with extreme weather, voters in the 1970s responded to a government call to move to drier land. The same spirit of innovation is needed today

What should governments – and people – do, confronted by the terrifying force of nature? It is the question of our age. But one answer, found on mainland Europe, serves as a reminder of human ingenuity in the face of adversity. The Netherlands offers perhaps the most astonishing example of government intervention in the 20th century: acting to deal with North Sea surges, which not only cost lives but threatened food production. The project involved the damming of the Zuiderzee – a large, shallow North Sea inlet – and the reclamation of land in the newly enclosed water. What has been created since 1972 is a new region to the east of Amsterdam, called Flevoland, out of the sea in the form of two great polders – essentially flat fields of reclaimed marshland which together are about the size of the English county of Dorset.

These days Flevoland is a busy place: containing the country’s fastest growing city of Almere, the regional capital of Lelystad, and a vast nature reserve, Oostvaardersplassen. Half a century ago, all were submerged metres below sea level. The country’s youngest province is living proof of how humankind can live with the ever-changing elements. Michel van Hulten, one of Flevoland’s architects and a former Dutch minister, says some of the success of the area is down to the collectivist spirit of the early 1970s when voters instinctively trusted government. He points out that there were no tax incentives or state subsidies for people to move to what were then empty new towns. The public simply answered the government’s call as part of a national mission. The Low Countries remain ideologically and historically close to the UK. The problem is that today’s politics is marked by polarisation rather than solidarity.

Philippines’ youth call for systemic change at climate protest

Protesters parading an effigy of Rodrigo Duterte in Manila call for policies that prioritise people and planet

A monstrous effigy of Philippine president Rodrigo Duterte was paraded through the country’s capital Manila on Friday as protesters joined a worldwide youth climate action.

About a hundred young people wearing masks gathered in one of several socially distanced demonstrations around the country in support of the global climate strike by the international Fridays for Future movement.

Rain falls on peak of Greenland ice cap for first time on record

Precipitation was so unexpected, scientists had no gauges to measure it, and is stark sign of climate crisis

Rain has fallen on the summit of Greenland’s huge ice cap for the first time on record. Temperatures are normally well below freezing on the 3,216-metre (10,551ft) peak, and the precipitation is a stark sign of the climate crisis.

Scientists at the US National Science Foundation’s summit station saw rain falling throughout 14 August but had no gauges to measure the fall because the precipitation was so unexpected. Across Greenland, an estimated 7bn tonnes of water was released from the clouds.

Greenland ice sheet on brink of major tipping point, says study

Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt

A significant part of the Greenland ice sheet is on the brink of a tipping point, after which accelerated melting would become inevitable even if global heating was halted, according to new research.

Rising temperatures caused by the climate crisis have already seen trillions of tonnes of Greenland’s ice pour into the ocean. Melting its ice sheet completely would eventually raise global sea level by 7 metres.

Greenland’s ice melting faster than at any time in past 12,000 years

Increased loss of ice could trigger sea level rise of up to 10cm by end of century

Greenland’s ice is starting to melt faster than at any time in the past 12,000 years, research has shown, which will raise sea levels and could have a marked impact on ocean currents.

New measurements show the rate of melting matches any in the geological record for the Holocene period – defined as the period since the last ice age – and is likely to accelerate, according to a paper published in the journal Nature.

Greenland ice sheet lost a record 1m tonnes of ice per minute in 2019

Climate-driven loss is likely to be the worst for centuries, and is pushing up sea levels

The Greenland ice sheet lost a record amount of ice in 2019, equivalent to a million tonnes per minute across the year, satellite data shows.

The climate crisis is heating the Arctic at double the rate in lower latitudes, and the ice cap is the biggest single contributor to sea level rise, which already imperils coasts around the world. The ice sheet shrank by 532bn tonnes last year as its surface melted and glaciers fell into the ocean and would have filled seven Olympic-sized swimming pools per second.

Sea levels could rise more than a metre by 2100, experts say

Oceans rising faster than previously thought, according to survey of 100 specialists

Sea-level rise is faster than previously believed and could exceed 1 metre by the end of the century unless global emissions are reduced, according to a survey of more than 100 specialists.

Based on new knowledge of climate sensitivity and polar ice melt, the experts say coastal cities should prepare for an impact that will hit sooner than predicted by the United Nations and could reach as high as 5 metres by 2300.
