New NASA-funded research has discovered that Arctic permafrost’s expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing. Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms […]
Dear Editor, In response to the recently published article entitled “Thawing Permafrost Microbiomes Fuel Climate Change,” it is increasingly evident that a bold and swift transition to renewable energy, and away from fossil fuels, is essential for maintaining a livable planet. Unforeseen variables, such as thawing permafrost carbon sinks, are only accelerating the rate of […]
A new study shows that as those fires scorched a region of boreal forest the size of Maryland, they released half as much carbon back into the atmosphere as all the plants, shrubs and trees in Canada typically store in an entire year. The Arctic is warming faster than any other region on Earth, and […]
Just outside my window here at the University of Alaska Fairbanks, workers are drilling into the asphalt of a parking lot using a truck-mounted rig. They twist a hollow bit 25 feet into the ground and pull up hard, clear evidence of why the blacktop is sinking. A few days ago, John Walsh gave a […]
