Although there are many different causes of browning events, there are also a number of commonalities among the impacts that they have.

Browning events are extreme climatic, biotic and physical disturbance events that can cause substantial loss of plant biomass and productivity, sometimes at scales of > 1000 km2, They are therefore key contributors to the spatial and temporal complexity of Arctic greening and vegetation dynamics.

Increasing certainty in projected local extreme precipitation change.
Some regions are going to have big increases in annual maximum daily precipitation, and this is now known with greater certainty.

Substantial and overlooked greenhouse gas emissions from deep Arctic lake sediment - Nature Geoscience
Deep permafrost soils produce comparable amounts of greenhouse gases as shallow soils in response to warming, according to incubation experiments of deep Arctic lake sediments.

Interesting paper: Substantial and overlooked greenhouse gas emissions from deep Arctic lake sediment.
Carbon release from deep sediment permafrost thaw (20m in this study) may be much more important for changing climate than thought.

Fire promotes arctic greening by facilitating establishment and growth of larger stature deciduous shrubs and other species. And the more severe fires do this more.
