Since the 1950s, research stations on the Antarctic Peninsula have recorded some of the largest increases in near-surface air temperature in the Southern Hemisphere. This warming has contributed to the regional retreat of glaciers, disintegration of floating ice shelves and a ‘greening’ through the expansion in range of various flora. Several interlinked processes have been suggested as contributing to the warming, including stratospheric ozone depletion, local sea-ice loss, an increase in… 
Dominant role of vertical air flows in the unprecedented warming on the Antarctic Peninsula in February 2020
Near-surface air temperature at the Argentinian research base Esperanza on the northern tip of the Antarctic Peninsula reached 18.3 °C on 6 February 2020, which is the highest temperature ever
Climate warming amplified the 2020 record-breaking heatwave in the Antarctic Peninsula
February 2020 was anomalously warm in the Antarctic Peninsula region and registered one of the most intense heatwaves ever recorded in Western Antarctica. The event featured unprecedented regional
Tropical teleconnection impacts on Antarctic climate changes
Over the modern satellite era, substantial climatic changes have been observed in the Antarctic, including atmospheric and oceanic warming, ice sheet thinning and a general Antarctic-wide expansion
Record warming at the South Pole during the past three decades
Over the last three decades, the South Pole has experienced a record-high statistically significant warming of 0.61 ± 0.34 °C per decade, more than three times the global average. Here, we use an
Role of the South Pacific Convergence Zone in West Antarctic Decadal Climate Variability
Regional atmospheric circulation along coastal West Antarctica associated with the Amundsen Sea Low (ASL) mediates ice shelf melt that governs Antarctica's contribution to global sea level rise. In
Ocean temperature impact on ice shelf extent in the eastern Antarctic Peninsula
Ocean warming contributes to the thinning of the Antarctic ice shelves, however, lack of observations has prevented a quantification of this contribution, and geological records are used to show that 0.3–1.5 °C ocean warming has played a central role on regional ice shelf instability over the last 9000 years.
Tropical forcing of increased Southern Ocean climate variability revealed by a 140-year subantarctic temperature reconstruction
Abstract. Occupying about 14 % of the world's surface, the Southern Ocean plays a fundamental role in ocean and atmosphere circulation, carbon cycling and Antarctic ice-sheet dynamics. Unfortunately,
Antarctic Peninsula warm winters influenced by Tasman Sea temperatures
It is shown that atmospheric response to SST warming over the Tasman Sea, even in the absence of anomalous tropical SST forcing, deepens the Amundsen Sea Low, leading to warm advection over the Antarctic Peninsula.
The Medieval Climate Anomaly in Antarctica
New regional insights into the stable water isotope signal at the northern Antarctic Peninsula as tools for climate studies
The Antarctic Peninsula is one of the most challenging regions of Antarctica from a climatological perspective, owing to the recent atmospheric and oceanic warming. The steep topography and a lack of


The Impact of a Changing Southern Hemisphere Annular Mode on Antarctic Peninsula Summer Temperatures
Since the mid-1960s, rapid regional summer warming has occurred on the east coast of the northern Antarctic Peninsula, with near-surface temperatures increasing by more than 2 degrees C. This warming
Temperature Change on the Antarctic Peninsula Linked to the Tropical Pacific
AbstractSignificant summer warming over the eastern Antarctic Peninsula in the last 50 years has been attributed to a strengthening of the circumpolar westerlies, widely believed to be anthropogenic
Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history
Warming for several centuries rendered ice shelves on the northeastern Antarctic Peninsula vulnerable to collapse, and continued warming to temperatures that now exceed the stable conditions of most of the Holocene epoch is likely to cause ice-shelf instability to encroach farther southward along the Antarctic Peninsula.
Recent Rapid Regional Climate Warming on the Antarctic Peninsula
The Intergovernmental Panel on Climate Change (IPCC) confirmed that mean global warming was 0.6 ± 0.2 °C during the 20th century and cited anthropogenic increases in greenhouse gases as the likely
Impacts of the north and tropical Atlantic Ocean on the Antarctic Peninsula and sea ice
It is suggested that the north and tropical Atlantic is important for projections of future climate change in Antarctica, and has the potential to affect the global thermohaline circulation and sea-level change.
Antarctic climate change over the twenty first century
[1] Here we present a new assessment of Antarctic climate change over the 21st century based on data from the models that were developed as part of the Intergovernmental Panel on Climate Change
Attribution of polar warming to human influence
Polar temperatures have been warming significantly over the past few decades. A comparison between observational temperature records and model simulations shows that temperature changes in both the
The central role of diminishing sea ice in recent Arctic temperature amplification
It is shown that the Arctic warming is strongest at the surface during most of the year and is primarily consistent with reductions in sea ice cover, and suggests that strong positive ice–temperature feedbacks have emerged in the Arctic, increasing the chances of further rapid warming and sea ice loss.
Interpretation of Recent Southern Hemisphere Climate Change
Evidence is presented that recent trends in the SH tropospheric circulation can be interpreted as a bias toward the high-index polarity of this pattern, with stronger westerly flow encircling the polar cap.
Decadal Changes in the Near-Surface Air Temperature in the Western Side of the Antarctic Peninsula
An analysis of the minimum air temperature behavior was carried out for the southern tip of South America and the western side of the Antarctica Peninsula. Punta Arenas shows an overall annual
