The Arctic-boreal zone covers ~ 20% of Earth's land surface and is characterized by cold temperatures, long winters, and permafrost. This region is extremely important because it holds over 50% of the global soil organic carbon pool, and is now warming four times faster than elsewhere on the planet. Historically cold protected soil carbon is becoming more vulnerable to loss as CO2 and CH4, threatening to shift the northern carbon budget into a net source if these emissions begin to outpace annual carbon uptake by plants, especially forests. Here I present recent insights gained from satellite-informed models, and field research, which provide new understandings of regional vulnerability (and perhaps resilience), and ecosystem-climate feedbacks.
