This is the 33rd issuance of the annual assessment now known as State of the Climate, published in the Bulletin since 1996. As a supplement to the Bulletin, its foremost function is to document the status and trajectory of many components of the climate system. However, as a series, the …

When Ernest Shackleton and his men marched towards the South Pole in December 1908, they came across something entirely unexpected. After scaling the vast Beardmore glacier on the edge of the polar plateau, they found seams of coal amid the snow and ice. They also found impressions of leaves in …
Antarctic Ice Sheet elevation changes, which are used to estimate changes in the mass of the interior regions, are caused by variations in the depth of the firn layer. We quantified the effects of temperature and accumulation variability on firn layer thickness by simulating the 1980
The Wilkins Ice Shelf in Antarctica has broken up further, with an area of about 160 square kilometres breaking off from May 30 to May 31, 2008. The Wilkins Ice Shelf, a broad plate of floating ice on the Antarctic Peninsula, is connected to two islands, Charcot and Latady. A …
Long-period seismic sources associated with glacier motion have been recently discovered, and an increase in ice flow over the past decade has been suggested on the basis of secular changes in such measurements. Their significance, however, remains uncertain, as a relationship to ice flow has not been confirmed by direct …
A strong earthquake with a 6.4 magnitude struck southwest of Australia's Macquarie Island early today, the US Geological Survey said. The epicentre of the quake, which hit at 12:31am (AEDT), was 745 kilometres southwest of the remote Australian territory, which lies about 1,450 kilometres southeast of the island state of …
The recently published 800,000-year greenhouse-gas records from Dome C, Antarctica, show that old ice still bears surprises. As long as the records challenge our understanding, we should go back for more. (Editorial)
In the global rush for resources, a tiny pink crustacean living in the seas around Antarctica is testing man's ability to manage one of the world's last great fisheries without damaging the environment. Krill, which grow to about 6 cm (2 inches), occur in vast schools and is the major …
Data laboriously extracted from an Antarctic ice core provide an unprecedented view of temperature, and levels of atmospheric carbon dioxide and methane, over the past 800,000 years of Earth's history.
The pesticide DDT, banned decades ago in much of the world, still shows up in penguins in Antarctica, probably due to the chemical's accumulation in melting glaciers, a sea bird expert said on Friday. Adelie penguins, known for their waddling gait and a habit of nesting on stones, have long …
Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research …
The Arctic and Antarctica are poles apart when it comes to the effects of human-fuelled climate change, scientists said on Friday: in the north, it is melting sea ice, but in the south, it powers winds that chill things down. The North and South poles are both subject to solar …
A unique drilling project in the western Ross Sea has revealed that Antarctica had a much more eventful climate history than previously assumed. A new sediment core hints that the western part of the now-frozen continent went through prolonged ice-free phases
Subglacial water can significantly affect the velocity of ice streams and outlet glaciers of ice sheets. Depending on the geometry and capacity of the subglacial hydrologic system, increased surface melting in Greenland over the coming decades may influence the ice sheet's mass balance. Furthermore, subglacial lakes in Antarctica can modulate …
The generally warm and ice-free conditions of the Eocene epoch rapidly declined to the cold and glaciated state of the Oligocene epoch. Geochemical evidence from deep-sea sediments resolves in detail the climatic events surrounding this transition.
The British Antarctic Survey has released images showing a sizable part of the Wilkins ice shelf off the Antarctic peninsula "hanging by a thread'. It is holding on to a thin strip of ice attached to the main island and scientists worry it might collapse soon. Remote sensing experts noticed …
The sea-ice cover in the polar regions is one of the most expansive and seasonal geophysical parameters on the earth's surface. The presence or absence of sea-ice affects the atmosphere and the ocean, and therefore the climate in many ways. In this study we have used the Multi-frequency Scanning Microwave …
