PARIS, France (AFP) – World leaders, scientists and major companies gather in France this week to boost efforts to protect the oceans, which cover 70 percent of the planet but receive far less attention than land ecosystems. The One Ocean Summit in the northwestern port city of Brest on February 9-11 seeks to raise the international community’s ambitions to protect sealife, cut plastic pollution and tackle the impact of climate change. The world’s five connected […]

World must work together to tackle plastic ocean threat: WWF
by Stéphane ORJOLLET Agence France-Presse PARIS, France (AFP) – Plastic has infiltrated all parts of the ocean and is now found “in the smallest plankton up to the largest whale” wildlife group WWF said on Tuesday, calling for urgent efforts to create an international treaty on plastics. Tiny fragments of plastic have reached even the most remote and seemingly-pristine regions of the planet: it peppers Arctic sea ice and has been found inside fish in […]
Mountain glaciers hold less ice than thought, and that’s bad news
by Marlowe HOOD Agence France-Presse PARIS, France (AFP) – Mountain glaciers shrinking due to climate change are less voluminous than previously understood, putting millions who depend on them for water supply at risk, researchers reported Monday. Glaciers in the Andes Mountains of South America, for example, were found to store 23 percent less fresh water compared to earlier estimates, they wrote in the journal Nature Geoscience. Bolivia’s largest city La Paz, with more than two […]
Corals doomed even if global climate goals met: study
by Marlowe HOOD Agence France-Presse PARIS, France (AFP) – Coral reefs that anchor a quarter of marine wildlife and the livelihoods of more than half-a-billion people will most likely be wiped out even if global warming is capped within Paris climate goals, researchers said Tuesday. An average increase of 1.5 degrees Celsius above pre-industrial levels would see more than 99 percent of the world’s coral reefs unable to recover from ever more frequent marine heat […]
Greenland ice cap loses enough water in 20 years to cover US: study
COPENHAGEN, Denmark (AFP) – Greenland’s immense ice sheet has lost enough ice in the past 20 years to submerge the entire United States in half a metre of water, according to data released this week by Danish researchers. The climate is warming faster in the Arctic than anywhere else on the planet and melting ice from Greenland is now the main factor in the rise in the Earth’s oceans, according to NASA. Since measurements began […]
Monster iceberg released ‘billions of tonnes’ of fresh water into ocean
by Amélie BOTTOLLIER-DEPOIS Agence France-Presse PARIS, France (AFP) – A giant iceberg that detached from Antarctica in 2017 released the equivalent of 61 million Olympic-sized swimming pools of fresh water as it melted, according to research published Thursday, raising questions over the impact on the marine ecosystem. The monstrous iceberg was twice the size of Luxembourg when it separated from the Larsen ice shelf, which has warmed faster than any other part of Earth’s southernmost […]
‘Remarkable’ giant coral reef found off Tahiti
by Kelly MACNAMARA Agence France-Presse PARIS, France (AFP) – Scientists have discovered a vast reef of “pristine” rose-shaped corals apparently unharmed by climate change in deep water off the coast of Tahiti, UNESCO announced Thursday. Mapping approximately three kilometres (two miles) long and up to 65 metres (213 feet) wide, UNESCO said it was “one of the most extensive healthy coral reefs on record”. The UN heritage agency said it was “highly unusual” to find […]
Coral reefs of western Indian Ocean at risk of collapse: study
by Nick Perry Agence France-Presse NAIROBI, Kenya (AFP) – Rising sea temperatures and overfishing threaten coral reefs in the western Indian Ocean with complete collapse in the next 50 years, according to a groundbreaking study of these marine ecosystems. The findings, published in the journal Nature Sustainability on Monday, warned that reefs along the eastern coast of Africa and island nations like Mauritius and Seychelles faced a high risk of extinction unless urgent action was […]
Into the ‘plastisphere’: Scientists comb Japan waters to study new eco threat
by Etienne BALMER and Hiroshi HIYAMA Agence France-Presse SHIMODA, Japa (AFP) – A boat’s crew casts a net into the seemingly clean waters off Japan’s Izu peninsula, but not to catch fish — they are scooping up microplastics to learn more about the pollution’s impact on marine life. Tiny floating fragments from plastic packaging, synthetic clothing and fishing nets have proliferated over the past four decades, and are now found in every part of the […]
Global warming kills 14 percent of world’s corals in a decade
by Marlowe HOOD Agence France-Presse PARIS, France (AFP) – Dynamite fishing and pollution — but mostly global warming — wiped out 14 percent of the world’s coral reefs from 2009 to 2018, leaving graveyards of bleached skeletons where vibrant ecosystems once thrived, according to the largest ever survey of coral health. Hardest hit were corals in South Asia and the Pacific, around the Arabian Peninsula, and off the coast of Australia, more than 300 scientists […]
Senegal’s old capital on the frontline against rising sea
by Laurent Lozano Agence France-Presse SAINT-LOUIS, Senegal (AFP) – In the northern Senegalese city of Saint-Louis, excavators are ripping up the beach to lay giant blocks of basalt, in an eleventh-hour effort to keep the sea at bay. When work is finished, a black sea wall will stretch for kilometres along the coastline of the West African country’s former capital, famed for its colonial-era architecture. Dire warnings about the risk of rising sea levels due […]
Dramatic shark decline leaves ‘gaping hole’ in ocean: study
by Sara HUSSEIN Agence France Presse Overfishing has wiped out over 70 percent of some shark and ray populations in the last half-century, leaving a “gaping, growing hole” in ocean life, according to a new study. Researchers found alarming declines in species ranging from hammerhead sharks to manta rays. Among the worst affected is the oceanic whitetip, a powerful shark often described as particularly dangerous to man, which now hovers on the edge of […]
