Surface Water - clean water for all

<r>Scientists have found that the AMOC may be far more vulnerable to rapid warming than to temperature alone. When warming happens slowly, the ocean can adapt, but at faster rates similar to today’s, the massive Atlantic circulation could reach a tipping point at much lower temperatures.<br/>

<r>Marine heatwaves are emerging as a threat not just to coral reefs and fisheries, but to human health and well-being. Researchers warn that unusually hot oceans can fuel stronger storms, trigger harmful algal blooms, reduce seafood supplies, disrupt livelihoods, and contribute to anxiety, grief ...

<r>Ancient seafloor sediments have revealed a surprising twist in how the Atlantic’s massive circulation system works. During a cold period about 3.4 million years ago, the flow of warm, salty water from the Indian Ocean into the Atlantic nearly shut down—but the AMOC did not weaken as expected ...

<r>Thawing Arctic permafrost is releasing ancient carbon into the ocean, raising fears that microbes could turn it into greenhouse gases and accelerate climate change. But sediment cores collected near Canada’s Herschel Island reveal a more reassuring twist: most of this land-based carbon becomes ...

<r>An AI analysis of 1.2 million satellite images shows that floating algae blooms are spreading across the global ocean. The rapid growth of massive seaweed mats could reshape marine habitats while bringing foul-smelling decay, ecological damage, and economic losses to coastlines.<br/>

<r>Coastal communities are facing a hidden threat that is making rising seas far more dangerous: the land beneath them is sinking. New research shows that people in densely populated coastal regions experience an average relative sea-level rise of about 6 millimeters per year, nearly three times the ...

<r>Deep beneath submarine volcanoes, Earth may be running a natural “gold kitchen.” By analyzing volcanic glass from the Kermadec island arc north of New Zealand, researchers found that water-rich mantle repeatedly melts beneath subduction zones, gradually concentrating gold in rising magma. The ...

<r>A weakening Atlantic current could supercharge California’s atmospheric rivers while leaving Greenland with fewer snow-producing storms. The changes could raise flood risks, strain infrastructure, and reshape water supplies far beyond the Atlantic.<br/>

<r>Ancient sediment reveals that some of K’gari’s deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the sacred lakes known as the Eyes of K’gari.<br/>
