Abstract Changes in vegetation productivity based on normalized difference vegetation
index (NDVI) have been reported from Arctic regions. Most studies use very coarse spatial …

Herbivores can exert a controlling effect on the reproduction and growth of shrubs, thereby
counter‐acting the climate‐driven encroachment of shrubs in the Arctic and the potential …

As an important component of the climate system, permafrost responds significantly to
climate change, and its impact on the ecosystem cannot be ignored. In this study, we …

Ongoing Arctic greening can increase productivity and reindeer pasture quality in the tundra.
However, greening may also entail proliferation of unpalatable species, with consequences …

The Arctic is one chapter from the State of the Climate in 2020 annual report and is available
from https://doi. org/10.1175/BAMS-D-21-0086.1. Compiled by NOAA's National Centers for …

The risk of carbon emissions from permafrost is linked to an increase in ground temperature
and thus in particular to thermal insulation by vegetation, soil layers and snow cover. Ground …

Some of the climate-sensitive infections (CSIs) affecting humans are zoonotic vector-borne
diseases, such as Lyme borreliosis (BOR) and tick-borne encephalitis (TBE), mostly linked …

Warming‐driven growth of tall woody vegetation in the Arctic has the potential to accelerate
climate change through multiple positive feedbacks. Local‐scale evidence suggests that …

Animal behavioural responses to the environment ultimately affect their survival. Monitoring
animal fine-scale behaviour may improve understanding of animal functional response to …

Rapid climate change has been driving changes in Arctic vegetation in recent decades, with
increased shrub dominance in many tundra ecosystems. Dendroecological observations of …
