The Arctic has warmed more than twice as fast as the global average since the late twentieth
century, a phenomenon known as Arctic amplification (AA). Recently, there have been …

Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

With the Arctic rapidly changing, the needs to observe, understand, and model the changes
are essential. To support these needs, an annual cycle of observations of atmospheric …

Mechanisms of Arctic amplification and Arctic climate change are difficult to pinpoint, and
current climate models do not represent the complex local processes and feedbacks at play …

Mechanisms behind the phenomenon of Arctic amplification are widely discussed. To
contribute to this debate, the (AC) 3 project was established in 2016 (www. ac3-tr. de/). It …

Abstract In the central Arctic Ocean the formation of clouds and their properties are sensitive
to the availability of cloud condensation nuclei (CCN). The vapors responsible for new …

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 …

Shallow clouds covering vast areas of the world's middle-and high-latitude oceans play a
key role in dampening the global temperature rise associated with CO 2. These clouds …

Global anthropogenic and legacy mercury (Hg) emissions are the main sources of Arctic Hg
contamination, primarily transported there via the atmosphere. This review summarizes the …

Clouds play an important role in Arctic amplification. This term represents the recently
observed enhanced warming of the Arctic relative to the global increase of near-surface air …
