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 buried in the seafloor, while only about 10 percent is converted into gases.
Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.
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.
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 global coastal average. Groundwater pumping, oil and gas extraction, heavy urban development, sediment compaction, and natural geological processes are all contributing to the problem.
Scientists have figured out how two famously poisonous plants create chemicals with surprising medical potential. After tracking thousands of genes in wolfsbane and larkspur, they identified six enzymes needed to build a complex compound called atisinium. The team recreated the process inside tobacco plants, offering a sustainable way to produce and test these rare molecules in larger amounts.
