DOI: 10.1007/s11356-022-18545-z
Abstract: Climate warming has intensified changes of permafrost freeze–thaw process and postponed the starting period of soil freezing, which significantly affected the processes of N2O production and emission from the soils. However, responses of soil N2O… read more here.

DOI: 10.1021/acs.est.1c06937
Abstract: In permafrost peatlands, up to 20% of total organic carbon (OC) is bound to reactive iron (Fe) minerals in the active layer overlying intact permafrost, potentially protecting OC from microbial degradation and transformation into greenhouse… read more here.

DOI: 10.3390/app13084856
Abstract: Climate change is likely to modify the freezing–thawing cycles in soils and surface waters of permafrost-affected and subarctic regions. However, the change of solution chemical composition during ice formation and the evolution of the remaining… read more here.
