Measuring how the Arctic responds to climate change

The Arctic has been warming more than twice as fast as the rest of the planet. Meanwhile CO2 measurements show substantial increases in the amount of carbon absorbed into and emitted by Arctic plants and soil. Scientists assumed this was playing a large role in changes to the Arctic carbon cycle. But they were not able to measure carbon uptake and release independently. This study provides insights into this important process based on the modelling of atmospheric measurements of carbonyl sulfide.
