As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the result of microbes waking up and digesting once-frozen organic materials. A new NASA-funded study focuses on a mechanism that could accelerate the release of this atmospheric carbon, the result of thermokarst lakes. These lakes form when thawing permafrost causes the ground to slump, creating a depression that collects rain and snowmelt and perpetuates a cycle of further permafrost thaw. || ", "release_date": "2018-08-17T11:00:00-04:00", "update_date": "2023-05-03T13:46:30.539381-04:00", "main_image": { "id": 400931, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a013000/a013047/Bubbles_Still.png", "filename": "Bubbles_Still.png", "media_type": "Image", "alt_text": "Music: Coveted Jewels by Reuben James Cornell [PRS]Complete transcript available.", "width": 1755, "height": 987, "pixels": 1732185 } } ], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
