When John Warmington first started diving the reefs outdoors his house in Vanuatu’s Havannah Harbour 10 years in the past, the coral rose like a sunken forest – tall stands of staghorns branched into yellow antlers, plate corals layered like canopies, and clouds of darting fish wove by means of the labyrinth.
“We used to know each inch of that reef,” he stated. “It was like a buddy.”
Now, it’s unrecognisable.
After Cyclone Pam battered the reef in 2015, sediment from inland rivers smothered the coral beds. Crown-of-thorns starfish swept in and devoured the recovering polyps.
Again-to-back cyclones in 2023 crushed what remained. Then, in December 2024, a magnitude 7.3 earthquake shook the seabed.
What stays is a coral graveyard – bleached rubble scattered throughout the seabed, habitats collapsed, and life vanished.
“We now have come out of the water in tears,” stated Warmington, who has logged hundreds of dives on this single reef. “We simply see heartbreak.”
That heartbreak is changing into extra frequent throughout this Pacific island nation, the place intensifying cyclones, rising seas, and saltwater intrusion are reshaping coastlines and threatening day by day life.
Since 1993, sea ranges round Vanuatu’s shores have risen by about 6mm (0.24in) per yr – considerably quicker than the worldwide common – and in some areas, tectonic exercise has doubled that charge.
On Wednesday, Vanuatu may have its day on the planet’s highest courtroom. The Worldwide Courtroom of Justice (ICJ) will subject an advisory opinion on what authorized obligations nations have to handle local weather change, and what penalties they could face if they don’t.
The case, led by Vanuatu and backed by greater than 130 international locations, is seen as a possible turning level in worldwide local weather regulation.
The opinion won’t be legally binding, however may assist form future efforts to carry main emitters accountable, and safe the funding and motion small island nations have to adapt or survive.
It comes after a long time of frustration for Pacific nations which have watched their homelands disappear.
In Tuvalu, the place the typical elevation is simply two metres (6.6ft), greater than a 3rd of the inhabitants has utilized for a local weather migration visa to Australia.
By 2100, a lot of the nation is projected to be beneath water at excessive tide.
In Nauru, the federal government has begun promoting passports to rich foreigners – providing visa-free entry to dozens of nations – in a bid to generate income for attainable relocation efforts.
Vanuatu has already sought opinions from different worldwide courts, and is pushing for the popularity of ecocide – the destruction of the atmosphere – as a criminal offense beneath the Worldwide Legal Courtroom.
Not all of those results may be attributed solely to local weather change, stated Christina Shaw, chief government of the Vanuatu Environmental Science Society.
Coastal growth, tectonic subsidence, volcanic eruptions, deforestation, and air pollution are additionally contributing to ecosystem decline.
“Vanuatu’s atmosphere is sort of fragile by its very nature in that it’s younger with slim reefs, has small quantities of topsoil, and is impacted often by pure disasters,” she stated. “However we do have to consider the opposite human impacts on our surroundings as properly.”
The harm isn’t restricted to properties, gardens, and reefs – it’s reaching into locations as soon as considered untouchable.
On the island of Pele, village chief Amos Kalsont sits at his brother’s grave as waves lap towards damaged headstones half-buried in sand.
At excessive tide, each his brother’s and father’s graves sit only a few arm’s lengths from the ocean. Some properties and gardens have already been moved inland, and saltwater intrusion has tainted the neighborhood’s major consuming water supply.
Now, the neighborhood is contemplating relocating the whole village – however that will imply leaving the land their grandparents cleared by hand.
Many in Vanuatu stay dedicated to constructing one thing stronger and hope the remainder of the world will assist them.
Again in Havannah Harbour, John Warmington nonetheless dives the reef he considers a part of his household. Whereas a lot of it has gone, he and his spouse Sandy have begun replanting coral fragments within the hope of restoring what stays.
