Global climate is changing faster than humankind has ever experienced. Model-based
predictions of future climate are becoming more complex and precise, but they still lack …

The aim of this work is (i) to review the recent studies on weather and climate change in
Finnish Sápmi and to present the literature review findings alongside our survey on the …

Human-induced climate warming by 2100 is expected to thaw large expanses of northern
permafrost peatlands. However, the spatio-temporal dynamics of permafrost peatland thaw …

High-latitude peatlands are changing rapidly in response to climate change, including
permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century …

It has been shown that reactive soil minerals, specifically iron (III)(oxyhydr) oxides, can trap
organic carbon in soils overlying intact permafrost, and may limit carbon mobilization and …

Climate warming and human impacts are thought to be causing peatlands to dry, potentially
converting them from sinks to sources of carbon. However, it is unclear whether the …

Aim Persistent sinks of atmospheric CO2 in undisturbed peatlands are not included in future
projections of the global carbon budget. We aimed to explore possible responses of …

Reductive dissolution during permafrost thaw releases iron-bound organic carbon to
porewaters, rendering previously stable carbon vulnerable to microbial decomposition and …

Peatlands are globally important stores of carbon (C) that contain a record of how their rates
of C accumulation have changed over time. Recently, near-surface peat has been used to …

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 …
