Warming amplification over the Arctic Pole (AP hereafter) and Third Pole (Tibetan Plateau,
TP hereafter) can trigger a series of climate responses and have global consequences …

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 …

Observations show that reduced regional sea-ice cover is coincident with cold mid-latitude
winters on interannual timescales. However, it remains unclear whether these observed …

Climate models predict a weak poleward shift of the jets in response to continuing climate
change. Here we revisit observed jet trends using 40 years of satellite-era reanalysis …

The surface temperature response to greenhouse gas forcing displays a characteristic
pattern of polar-amplified warming,,,–, particularly in the Northern Hemisphere. However, the …

We analyze the polar sea ice distribution and the global sea level pressure (SLP) and
baroclinicity distributions over the “satellite” period of 1979–2020. In the Arctic, there are …

The anthropogenically forced decline of Arctic sea ice is superimposed on strong internal
variability. Possible drivers for this variability include fluctuations in surface albedo, clouds …

Abrupt climate change is a striking feature of many climate records, particularly the warming
events in Greenland ice cores. These abrupt and high-amplitude events were tightly coupled …

During recent decades Arctic sea ice variability and retreat during winter have largely been
a result of variable ocean heat transport (OHT). Here we use the Community Earth System …

Pronounced changes in the Arctic environment add a new potential driver of anomalous
weather patterns in midlatitudes that affect billions of people. Recent studies of these …
