TL;DR: In this article, key observational indicators of climate change in the Arctic, most spanning a 47-year period (1971-2017) demonstrate fundamental changes among nine key elements of the Arctic system.

TL;DR: It is found that plant phenological and physiological properties can be integrated in a robust index—the product of the length of CO2 uptake period and the seasonal maximal photosynthesis—to explain the GPP variability over space and time in response to climate extremes and during recovery after disturbance.

TL;DR: In this article, the average summertime net ecosystem exchange of CO2 (NEE) was highly variable between sites, and all sites with complete annual datasets, seven in total, acted as annual net sinks for atmospheric CO2.

TL;DR: In this paper, the authors synthesize regional in situ observations of CO2 flux from Arctic and boreal soils to assess current and future winter carbon losses from the northern permafrost domain.

TL;DR: The results quantify the role of human activities on the climate footprint of northern wetlands and call for development of active mitigation strategies for managed wetlands and new guidelines of the Intergovernmental Panel on Climate Change accounting for both sustained CH4 emissions and cumulative CO2 exchange.
