Enterrer les arbres tués par les incendies pour séquestrer le carbone

Un projet dans le Montana a permis d'enterrer des milliers d'arbres morts à la suite d'un incendie en 2021, dans le but de stocker leur carbone sous terre pour des siècles. Cette méthode, adoptée par l'entreprise Mast Reforestation, remplace la pratique habituelle qui consiste à brûler les arbres en tas. Elle permet également à la société de vendre des crédits carbone tout en replantant de nouveaux arbres sur le site.

En 2021, un incendie de forêt à Poverty Flats a ravagé 267 kilomètres carrés et tué 50 000 pins ponderosa sur le ranch Gentry. Au lieu d'empiler et de brûler les arbres morts, ce qui aurait libéré près de 7 000 tonnes de dioxyde de carbone, les équipes ont placé les troncs dans une fosse de 5 000 mètres carrés et les ont recouverts de six mètres de terre, de gravier et d'une membrane géotextile.

Arctic wildfires release carbon stored for thousands of years

Wildfires raging across Arctic and boreal regions are igniting ancient carbon in soils, releasing far more carbon dioxide than climate models have assumed. A new study of soil cores shows that some fires are burning organic matter up to 5,000 years old.

Study reveals underestimated carbon emissions from boreal wildfires

A new study from UC Berkeley indicates that climate models may significantly underestimate carbon emissions from wildfires in boreal forests due to overlooked peat soil burning. Researchers analyzed 2018 wildfires in Sweden and found that smoldering underground fires release ancient carbon stored for centuries. This discrepancy highlights potential gaps in global emission estimates, especially in vast regions like Siberia and Canada.

Arctic peatlands expand as warming creates feedback risks

A new study reveals that peatlands in the Arctic are growing due to rapid regional warming and increased precipitation, potentially storing more carbon but also heightening the risk of releases through fires. Researchers warn of a dangerous feedback loop as these carbon-rich ecosystems respond to climate changes. The findings highlight the dual role of these landscapes in global warming mitigation.

Raising water levels cuts emissions in Arctic peatlands

A two-year study in northern Norway shows that elevating groundwater in drained Arctic peatlands significantly reduces carbon dioxide emissions and can even turn the land into a net carbon sink. Researchers at NIBIO's Svanhovd station found that higher water levels limit microbial activity while maintaining low methane and nitrous oxide emissions. The findings highlight potential climate benefits for cold northern farmlands.
