Azores create largest marine protected area in North Atlantic

The regional assembly of Portugal's Azores Islands approved the creation of the largest protected marine area in the North Atlantic to reach international conservation goals well ahead of time. The approval late on Thursday places the archipelago at the forefront of global ocean conservation that aims to achieve the goals set by the United Nations of protecting 30% of the Earth's land and sea by 2030 under a global pact adopted last year.

Sea life bounced back fast after the ‘mother of mass extinctions’

A treasure trove of fossils uncovered in China challenges the idea that marine animals took millions of years to recover from the world’s worst die-off An exceptionally well-preserved trove of fossils uncovered in southern China represents a complex marine ecosystem from the dawn of modern life, according to a study published in Science today. The organisms of the Guiyang biota lived around 251 million years ago, just one million years after the world’s worst known mass-extinction event, at the end of the Permian period. This suggests that ecosystems recovered much more rapidly than previously thought. Palaeontologist Xu Dai discovered the fossils in 2015, when he was at the China University of Geosciences in Wuhan. Between 2015 and 2019 — before the COVID-19 pandemic interrupted ...

New research from Queen’s University Belfast has led to 184 deep-sea species being added to the global Red List of Threatened Species. With almost two-thirds of the species assessed listed as threatened, it highlights the urgent need to protect them from extinction. The International Union for Conservation of Nature (IUCN)’s Red List of Threatened Species is the world’s foremost conservation authority, with universally recognised extinction risk categories (e.g. Endangered, Critically Endangered, etc.) used to raise awareness of species’ conservation needs to industry, policy makers, and the general public. More than 140,000 species have been Red Listed but less than 15% are from marine environments and barely any are from the deep sea. The deep sea is the largest en...

Coral reefs off east Africa could die out in 50 years

A new study found warming temperatures to be the main driver Coral reefs in the western Indian Ocean are at risk of extinction by 2070 due to warming temperatures and overfishing, according to a new study. A roughly 12,000 sq km expanse of coral reefs stretching down the eastern coastline of Africa and around Madagascar is facing ecosystem collapse, threatening a range of species and the livelihoods of over a million people who work in the fishing and tourism industries. These reefs make up around 5% of the planet's total coral reef area. "When an ecosystem collapses, we might still see individual fish or corals but the whole system is no longer effective in supporting either marine biodiversity or communities who are dependent on it," said David Obura, a Kenyan marine ecolog...

Blue Print: Belize offers to protect reef in exchange for debt relief

Belize provided a likely 'blue' model for conserving some of the world's most vulnerable marine ecosystems on Friday, swapping a promise to protect the northern Hemisphere's biggest barrier reef for much-needed debt relief. While urgent efforts to limit global warming are expected to see at least half a trillion dollars of 'green' bonds this year, 'blue' bonds are still in their infancy, despite estimates that oceans contribute around $3 trillion per year to global GDP. Financial incentives have been one of the main pillars of efforts at the United Nations COP26 climate change summit to tackle rising temperatures, with demands from poorer countries for increased help from richer states.
