The world's oceans experienced their hottest June ever, with European Union monitors noting the first half of 2026 was marked by sustained and exceptional ocean warmth.

The world's oceans recorded their hottest June ever, according to European scientists. They warned that the emergence of an El Niño weather pattern combined with human-driven climate change could lead to new temperature records in the coming months.

Africa is hosting global ocean negotiations for the first time, addressing the urgent decline of oceans that absorb a third of the world's carbon and feed billions. The negotiations highlight the critical need for action as oceans are dying faster than governments can respond.

The UN warns of a 'deepening crisis' in the oceans, which cover 70% of the planet and are critical to the global ecosystem, urging urgent global action against threats like global warming, pollution, and loss of marine life. A five-year report by 600 international scientists highlights the risk of an ice-free Arctic as early as the 2030s.

Scientists developed a solar desalination system using laser-textured metal panels to convert seawater into drinking water without producing toxic brine. The system prevents clogging by moving salt deposits away, was tested in three oceans, and recovers nearly all salts as solids, including lithium for batteries.

BBC Inside Science is covering the Hay Festival 2026, focusing on a significant year for oceans. The article highlights a 'big year' for marine environments as part of the festival's theme.

Sea levels are rising at an accelerating rate due to warming seawater, melting glaciers, and polar ice sheets. Scientists have resolved a long-standing discrepancy in sea level measurements.

Fossil evidence suggests giant octopuses, up to 19 meters in size, may have dominated ancient oceans 100 million years ago. The discovery highlights the evolutionary history of cephalopods and their dominance in prehistoric marine ecosystems.

A study reveals that giant octopuses, comparable in size to sperm whales, existed in Earth's oceans 72 million years ago. This discovery sheds light on ancient marine ecosystems and the diversity of prehistoric cephalopods.

A study reveals that giant octopuses, comparable in size to sperm whales, existed 72 million years ago. These ancient cephalopods roamed the oceans during the late Cretaceous period.

A study reveals that warming ocean temperatures are causing great white sharks to overheat, threatening their survival. The research highlights the impact of climate change on marine species' physiology and behavior.
