Antarctic Peninsula (69°30′ S 065°00′ W) is the northernmost part of the mainland of Antarctica, and the only part of that continent that extends outside the Antarctic Circle.
The first sighting of Antarctic Peninsula is contested but it apparently occurred in the 1820s.

The peninsula is surrounded by numerous islands, including the South Shetlands and the Palmer Archipelago.
The northwest coast of the peninsula is believed to have been mapped by the British navigator James Bransfield in Jan., 1820, and was explored by sealers in 1820–21.
First considered to be part of the continent, the peninsula was later (1928) thought to be a group of islands; the John Rymill expedition (1934–37) proved its peninsularity.

The Antarctic polar climate boundary -- the 50° F (10°C) isotherm for the warmest month -- encompasses about 12 percent of the surface of the globe, an area twice as large as that of the Arctic.
The coastal areas of the Antarctic continent are characterized by somewhat milder temperatures and much higher precipitation rates, mainly occurring as snow.
Peninsula extends much further north than the rest of the continent and is characterized by a warmer and wetter climate than the coastal areas, with above-freezing temperatures common.

 Antarctic Peninsula Climate Variability Workshop - Simmonds Abstract
The region centered on the Antarctic Peninsula is increasingly being seen as a 'hot spot' in Southern Hemisphere (SH) climate.
In the past the poor observational record of this region of the Antarctic, and of the SH as a whole, has militated against being able to see these changes in a broader perspective, and has meant that analyses of climate variability and change have had to be undertaken with caution.
In more recent times the acquisition of data from a wide variety of platforms (e.g., satellites, AWSs) and the application of sophisticated integrating techniques have meant that we now have at our disposal representations of the SH weather and climate over the last 4 or 5 decades which are far superior to those used heretofore.

 EO News: Glaciers from Antarctic Peninsula in Widespread Retreat, Science Study Says - April 21, 2005
The first comprehensive study of glaciers on Antarctic Peninsula has uncovered widespread glacier retreat and suggests that recent climate change on the peninsula is responsible.
With these photos and satellite images, Alison Cook from the British Antarctic Survey in Cambridge, U.K. and her team compiled a record of the behavior of glacier-ice shelves and tidewater glaciers along the coasts of the Antarctic Peninsula over the last half-century.
The Antarctic Peninsula glaciers have a complex response to climate change that may also involve variables such as ocean temperature, for which researchers have little data at present.

 USGS Fact Sheet 017-02: Coastal-Change and Glaciological Maps of the Antarctic Peninsula
Locations and names of three Antarctic Peninsula areas for which the U.S. Geological Survey and the British Antarctic Survey are preparing coastal-change and glaciological maps (I-2600-A, B, and C, scale 1:1,000,000).
For much of the Antarctic Peninsula, the BAS has used a georeferenced digital image mosaic from Landsat Thematic Mapper images prepared by the Institut für Angewandt Geodäsie (now the Bundesamt für Kartographie und Geodäsie) in Germany as an image-map base (backdrop).
The pronounced glaciological changes occurring in the Antarctic Peninsula region are the probable result of regional climate warming (+2.5°C since meteorological observations were initiated in the 1940s) and may even have global-climate-change implications.

From 1964 the northern area was universally known as Graham Land, the southern area as Palmer Land, and the peninsula as a whole as the Antarctic Peninsula.

 naturalSCIENCE, Volume 1, Article 6, 1997
Recent changes to ice shelves around the northern Antarctic Peninsula have inspired various environmentally-minded groups to warn that Antarctic ice is about to become a victim of "global climate warming." There is clearly a connection between warming around the Antarctic Peninsula and the collapse of peninsular ice shelves.
However, temperatures in the interior of the continent have remained fairly constant (Mosely-Thompson 1992) and it is not yet known whether the observed warming is part of a global trend or is simply a normal fluctuation in local climate.
Melted, Antarctic ice would contribute 66 meters to global sea level (that figure accounts for changes in salinity and for back-filling of the Antarctic continent with water once the ice is removed).

 Antarctic Peninsula Climate Variability Workshop - King Abstract
It is fortunate that the Antarctic Peninsula, which is arguably the most climatologically interesting part of Antarctica, possesses some of the longest and most complete climate records from the continent.
Interannual temperature variations on the Peninsula have been shown to be associated with changing atmospheric circulation patterns and with sea ice extent to the west of the Peninsula.
The observed pattern of Peninsula warming is not inconsistent with a regional enhancement of anthropogenic "greenhouse" warming as a result of local air-sea-ice interaction processes.
