BELHAVEN, N.C. (AP) \u2014 Investors and scientists are restoring a 23-square-mile (60-square-kilometer) tract of peatland in North Carolina\u2019s Inner Banks to curb emissions of climate-warming carbon dioxide and regenerate native habitat.<\/a><\/span><\/p>\n Fifty miles (80 kilometers) of ditches dug decades ago for an abandoned farming venture drained much of the water from thousands of years of accumulated peat \u2014 partially decayed organic matter up to 15 feet (4.6 meters) deep \u2014 leaving the site vulnerable to drought<\/a><\/span> and wildfires<\/a><\/span>, altering native habitats and allowing it to emit 130,000 tons of carbon dioxide every year.<\/p>\n Here are key takeaways from The Associated Press\u2019 reporting:<\/p>\n Though they account for just 3% of the global land surface, peatlands store about one-third of the Earth\u2019s carbon dioxide, more than all forests combined. But when degraded, destroyed or burned they become part of the problem, releasing huge volumes of greenhouse gases<\/a><\/span>, now about 6% of the annual global total from all sources.<\/p>\n When peatlands are intact, gases generated by decomposing plants are trapped in a waterlogged, oxygen-deprived environment, while surface vegetation absorbs carbon dioxide from the atmosphere, scientists say.<\/p>\n They also store about 10% of global fresh water, help control flooding and can help stem wildfires, as well as provide important habitat for many species.<\/p>\n Two-thirds of temperate peatlands \u2014 mostly in Europe and the U.S. \u2014 have been dewatered for farming, mining and other uses, while about 45% of tropical peatlands have been similarly disturbed, according to a 2025 study<\/a><\/span> published by The Society for Conservation Biology.<\/p>\n Boreal peatlands, in colder climates in places like Canada and Russia, are about 90% intact, but face growing pressure from thawing permafrost and intense fires, both linked to climate change, as well as mining and critical minerals exploration.<\/p>\nWhy are peatlands important?<\/h2>\n
