Abstract Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental dri

In the Arctic waterbodies are abundant and rapid thaw of permafrost is destabilizing the carbon cycle and changing hydrology. It is particularly important to quantify and accurately scale aquatic carbon emissions in arctic ecosystems. Recently availa

Landfills are a source of malodors, greenhouse gases, harmful pollutants, pests, noise, and litter. To reduce their impact on neighboring communities, landfill facilities and the policies they follow must reduce emissions of trace gases such as hydro

Cities are beginning to monitor atmospheric carbon dioxide (CO _2 ) to assess the efficacy of their climate policies. However, changes in anthropogenic CO _2 emissions must be separated from biospheric CO _2 fluxes which have a large seasonal cycle.

Soil respiration (i.e. from soils and roots) provides one of the largest global fluxes of carbon dioxide (CO _2 ) to the atmosphere and is likely to increase with warming, yet the magnitude of soil respiration from rapidly thawing Arctic-boreal regio

Methane (CH4) is a strong greenhouse gas that has become the focus of climate mitigation policies in recent years. Ethane / methane ratios can be used to identify and partition the difference sources of methane, especially in areas with natural gas m

Long-term atmospheric CO2 concentration records have suggested a reduction in the positive effect of warming on high-latitude carbon uptake since the 1990s. A variety of mechanisms have been proposed to explain the reduced net carbon sink of northern

Approximately half of the carbon dioxide (CO 2) released annually by the combustion of fossil fuels stays in the atmosphere (Friedlingstein et al., 2022; Keeling et al., 1976; Schimel et al., 2001). The remaining CO 2 is taken up by the terrestrial b
