Arctic amplification (AA)—referring to the enhancement of near-surface air temperature
change over the Arctic relative to lower latitudes—is a prominent feature of climate change …

The concept of feedback is key in assessing whether a perturbation to a system is amplified
or damped by mechanisms internal to the system. In polar regions, climate dynamics are …

As a step towards understanding the fundamental drivers of polar climate change, we
evaluate contributions to polar warming and its seasonal and hemispheric asymmetries in …

Arctic amplification (AA) is a coupled atmosphere-sea ice-ocean process. This
understanding has evolved from the early concept of AA, as a consequence of snow-ice line …

Water vapor is a greenhouse gas that dominates Earth's terrestrial radiation absorption. As
the planetary temperature warms, forced by increasing CO 2 and other greenhouse gases …

Abstract Greenland Ice Sheet (GrIS) mass loss has accelerated since the turn of the twenty‐
first century. Several recent episodes of rapid GrIS ablation coincided with intense moisture …

Arctic amplification of anthropogenic climate change is widely attributed to the sea-ice
albedo feedback, with its attendant increase in absorbed solar radiation, and to the effect of …

The Arctic warming response to greenhouse gas forcing is substantially greater than the rest
of the globe. It has been suggested that this phenomenon, commonly referred to as Arctic …

In this review, we highlight the complementary relationship between simple and
comprehensive models in addressing key scientific questions to describe Earth's …

Meridional atmospheric heat transport (AHT) has been investigated through three broad
perspectives: a dynamic perspective, linking AHT to the poleward flux of moist static energy …
