The Arctic is a region in transformation. Warming in the region has been amplified, as
expected from ice‐albedo feedback effects, with the rate of warming observed to be∼ …

The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and
human/cultural systems that may be irreversible on century time scales and have the …

Disturbance regimes are changing rapidly, and the consequences of such changes for
ecosystems and linked social‐ecological systems will be profound. This paper synthesizes …

The carbon (C) cycle in boreal regions is strongly influenced by fire, which converts biomass
and detrital C mainly to gaseous forms (CO 2 and smaller proportions of CO and CH 4), and …

The Lagrangian particle dispersion model FLEXPART was used to construct a global data
set of 1.4 million continuous trajectories. At the model start, particles were distributed …

The Arctic region is a harbinger of global change and is warming at a rate higher than the
global average. While Arctic warming is driven by increases in anthropogenic greenhouse …

Summertime wildfire activity is increasing in boreal forest and tundra ecosystems in the
Northern Hemisphere. However, the impact of long range transport and deposition of wildfire …

During the ARCPAC (Aerosol, Radiation, and Cloud Processes affecting Arctic Climate)
airborne field experiment in April 2008 in northern Alaska, about 50 plumes were …

During summer of 2004, about 2.7 million hectare of boreal forest burned in Alaska, the
largest annual area burned on record, and another 3.1 million hectare burned in Canada …

The global cryosphere, Earth's frozen water, is in precipitous decline. The ongoing and
predicted impacts of cryosphere loss are diverse, ranging from disappearance of entire …
