Rapid Arctic environmental change affects the entire Earth system as thawing permafrost
ecosystems release greenhouse gases to the atmosphere. Understanding how much …

This article provides a synthesis of the latest observational trends and projections for the
future of the Arctic. First, the Arctic is already changing rapidly as a result of climate change …

The permafrost zone is expected to be a substantial carbon source to the atmosphere, yet
large-scale models currently only simulate gradual changes in seasonally thawed soil …

The carbon balance of peatlands is predicted to shift from a sink to a source this century.
However, peatland ecosystems are still omitted from the main Earth system models that are …

Many feedback loops significantly increase warming due to greenhouse gas emissions.
However, not all of these feedbacks are fully accounted for in climate models. Thus …

The purpose of this conceptual paper is to provide readers with an opportunity to reassess
their work and life in the face of an inevitable near term social collapse due to climate …

Soil is a key component of Earth's critical zone. It provides essential services for agricultural
production, plant growth, animal habitation, biodiversity, carbon sequestration and …

Dissolved organic matter (DOM) is recognized for its importance in freshwater ecosystems,
but historical reliance on DOM quantity rather than indicators of DOM composition has led to …

Large quantities of organic carbon are stored in frozen soils (permafrost) within Arctic and
sub-Arctic regions. A warming climate can induce environmental changes that accelerate …

Exploring the source, transformation pathways, and the fate of natural organic matter (NOM)
is critical to understanding the regional/global carbon cycle and carbon budget. The …
