The microscopic parasite, named Algophthora mediterranea, attacks algae such as Ostreopsis cf. ovata, which produces toxins that can irritate the lungs, skin, and eyes of people exposed during coastal blooms. Remarkably, the fungus can infect several different algae species and even survive on pollen, suggesting it is far more adaptable than most known marine parasites.

A temporary slowdown in the atmosphere’s ability to break down methane allowed the gas to linger, while unusually wet conditions boosted emissions from wetlands, rivers, lakes, and rice fields around the world. Pandemic-related changes in air pollution played a key role, indirectly weakening the atmosphere’s natural “clean-up” process.

A massive global analysis of more than 31,000 tree species reveals that forests are becoming more uniform, increasingly dominated by fast-growing “sprinter” trees, while slow-growing, long-lived species are disappearing. These slower species act as the backbone of forest ecosystems, storing carbon, stabilizing environments, and supporting rich webs of life—especially in tropical regions where biodiversity is highest. Mon, 09 Feb 2026 02:17:56 EST https://www.sciencedaily.com/releases/2026/02/260208233836.htm https://www.sciencedaily.com/releases/2026/02/260208011024.htm Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling carbon from the atmosphere and helping lock it away in the deep ocean. New research shows these microscopic engineers are largely missing from the climate models used to forecast our planet’s future, meaning scientists may be underestimating how the ocean responds to climate change. Sun, 08 Feb 2026 01:36:40 EST https://www.sciencedaily.com/releases/2026/02/260208011024.htm https://www.sciencedaily.com/releases/2026/02/260204042457.htm Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice does not automatically boost carbon absorption. In the future, Antarctic ice loss could actually reduce the ocean’s ability to slow climate change. Wed, 04 Feb 2026 04:32:51 EST https://www.sciencedaily.com/releases/2026/02/260204042457.htm https://www.sciencedaily.com/releases/2026/02/260201231205.htm SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change. Under stress, many cells keep copying their DNA without dividing, creating abnormal cells that grow large and die. This vulnerability may explain why SAR11 populations drop during phytoplankton blooms and could become more important as oceans grow less stable. Mon, 02 Feb 2026 09:21:36 EST https://www.sciencedaily.com/releases/2026/02/260201231205.htm https://www.sciencedaily.com/releases/2026/01/260129080422.htm Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying expectations. Powerful monsoons and ocean circulation appear to have delayed oxygen loss in this region compared to the Pacific. The discovery suggests future ocean oxygen levels may not follow a simple warming-equals-deoxygenation rule. Thu, 29 Jan 2026 09:12:18 EST https://www.sciencedaily.com/releases/2026/01/260129080422.htm https://www.sciencedaily.com/releases/2026/01/260116035322.htm Tiny plastic particles drifting through the oceans may be quietly weakening one of Earth’s most powerful climate defenses. New research suggests microplastics are disrupting marine life that helps oceans absorb carbon dioxide, while also releasing greenhouse gases as they break down. By interfering with plankton, microbes, and natural carbon cycles, these pollutants reduce the ocean’s ability to regulate global temperatures. Sat, 17 Jan 2026 21:58:02 EST https://www.sciencedaily.com/releases/2026/01/260116035322.htm https://www.sciencedaily.com/releases/2026/01/260114084115.htm Scientists have identified a newly recognized threat lurking beneath the ocean’s surface: sudden episodes of underwater darkness that can last days or even months. Caused by storms, sediment runoff, algae blooms, and murky water, these “marine darkwaves” dramatically reduce light reaching the seafloor, putting kelp forests, seagrass, and other light-dependent life at risk. Wed, 14 Jan 2026 09:45:06 EST https://www.sciencedaily.com/releases/2026/01/260114084115.htm https://www.sciencedaily.com/releases/2026/01/260114080328.htm Earth’s oceans reached their highest heat levels on record in 2025, absorbing vast amounts of excess energy from the atmosphere. This steady buildup has accelerated since the 1990s and is now driving stronger storms, heavier rainfall, and rising sea levels. While surface temperatures fluctuate year to year, the ocean’s long-term warming trend shows no sign of slowing. Wed, 14 Jan 2026 08:36:08 EST https://www.sciencedaily.com/releases/2026/01/260114080328.htm https://www.sciencedaily.com/releases/2026/01/260112001034.htm Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters. Climate-driven changes may reduce iron delivery to the oceans, weakening the base of marine food chains. Over time, this could mean fewer krill and fewer whales, seals, and penguins. Mon, 12 Jan 2026 09:01:37 EST https://www.sciencedaily.com/releases/2026/01/260112001034.htm https://www.sciencedaily.com/releases/2026/01/260103155030.htm Overfished coral reefs are producing far less food than they could. Researchers found that letting reef fish populations recover could boost sustainable fish yields by nearly 50%, creating millions of extra meals each year. Countries with high hunger and nutrient deficiencies would benefit the most. Rebuilding reefs could turn ocean conservation into a powerful tool against global hunger. Sun, 04 Jan 2026 02:09:19 EST https://www.sciencedaily.com/releases/2026/01/260103155030.htm https://www.sciencedaily.com/releases/2025/12/251221043231.htm Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff fuels plankton blooms that bury huge amounts of carbon in the ocean. In low-oxygen conditions, this process can spiral out of control, cooling Earth far beyond its original state. While this won’t save us from modern climate change, it may explain Earth’s most extreme ancient ice ages.

Coral cores reveal that this nutrient engine has intensified over the past decade, perfectly matching surges in Sargassum growth since 2011. By ruling out older theories involving Saharan dust and river runoff, researchers uncovered a climate-driven process that shapes when and where these colossal seaweed mats form.

Despite models predicting a decline, researchers found that freshening surface waters are currently keeping deep CO2 trapped below. This stratification effect may be only temporary, as intensifying winds bring deep, carbon-rich water closer to the surface. If mixing increases, the Southern Ocean could begin releasing more CO2 than it absorbs.
