Researchers and volunteers worldwide are expanding projects to restore kelp forests hit hard by rising ocean temperatures. Efforts focus on removing sea urchins and developing heat-tolerant kelp strains. These initiatives aim to reverse losses that have reached 40 to 60 percent in recent decades.

Kenya itakuwa taifa la kwanza barani Afrika kuandaa Our Ocean Conference kati ya Juni 16 na 18 katika kaunti za Mombasa na Kilifi.
A study reveals that the Arabian Sea had more dissolved oxygen 16 million years ago than today, despite global temperatures being warmer during the Miocene Climatic Optimum. This challenges simple assumptions about warming leading to immediate ocean deoxygenation. Regional factors like monsoons and currents delayed severe oxygen loss in the area.

Researchers are returning to the Clarion-Clipperton Zone in the Pacific Ocean to investigate how metallic nodules produce oxygen without sunlight, a phenomenon dubbed 'dark oxygen' that could sustain deep-sea life. This discovery has sparked debate over the environmental risks of deep-sea mining for critical metals. The team aims to confirm the process and address criticisms from mining interests.
New research warns that even if humanity achieves net-negative emissions and cools the planet, the Southern Ocean might suddenly release its accumulated heat, restarting warming. This 'burp' could persist for at least a century. Scientists emphasize the need for rapid emission cuts to minimize such risks.

A group of 160 scientists from 23 countries has declared that the widespread death of warm-water coral reefs marks Earth's first major tipping point due to climate change. This irreversible shift is driven by rising marine temperatures and ocean acidification, with half of the world's live coral cover lost in the past half century. While recovery is possible with urgent action, the report warns of escalating global risks if emissions continue unchecked.
