Ocean acidification, driven by the uptake of anthropogenic carbon dioxide, is reshaping marine ecosystems by altering seawater chemistry in ways that affect organismal physiology, community structure ...

An international research team develops a rubric for governments and policymaking bodies to evaluate preparedness for ocean acidification. In a paper published today in the journal Environmental ...

New research has shown that by injecting an alkalinizing agent into the ocean along the length of the Great Barrier Reef, it would be possible, at the present rate of anthropogenic carbon emissions, ...

The oceans have absorbed a significant portion of all anthropogenic (CO 2) emissions (approximately a third of the CO 2 emitted from fossil fuel emissions, cement production and deforestation; Sabine ...

Scientists at the Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) have for the first time shown that increased acidification of ...

While the livelihoods of more than three billion people depend on oceanic resources, the ocean also provides a large fraction of the oxygen we breathe and absorbs greenhouse gases, mitigating their ...

Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems. In June 2025, a study found that ...

The world’s oceans absorb about a quarter of humanity’s carbon dioxide emissions, buffering us against higher atmospheric CO2 levels and greater climate change. But that absorption has led to a ...

Wei-Jun Cai, an expert in marine chemistry at the University of Delaware, is sounding new alarm bells about the changing chemistry of the western region of the Arctic Ocean, where he and an ...

A critical measure of the ocean’s health suggests that the world’s marine systems are in greater peril than scientists had previously realized and that parts of the ocean have already reached ...
