The cause of the variability in atmospheric CO2 over glacial-interglacial timescales has been a puzzle since its discovery in the early 1980s. It is widely believed to be related to …
During the Last Interglacial (129-116 thousand years ago, ka) CO2 and global temperature were both higher than they were before human industrialisation. By examining Last Interglacial climate, we thus gain …
The Antarctic Peninsula and West Antarctica have warmed dramatically in recent decades, with some climate records indicating that these are among the most rapidly warming regions on Earth. The Antarctic …
Changes in wind strength and circulation patterns above the Antarctic Peninsula are linked to its warming and increased upwelling of warm circumpolar deep water, resulting in accelerated melting and thinning …
In order to assess the impact of anthropogenic carbon dioxide (CO2) on the oceans today we are investigating the effect of decreasing upper ocean pH on calcifying zooplankton. Pteropods, …
In this NERC-funded project, we are generating Southern Hemisphere Westerlies (SHW) proxy records from each of the three major sectors of the Southern Ocean, focusing on subantarctic islands situated in …
This research focuses on investigating the glacial histories of Arctic ice sheets and ice caps using the marine geological record preserved on continental margins. By reconstructing past ice sheets, their …
This project will reconstruct millennial-scale ice sheet change in the western Amundsen Sea Embayment, Antarctica, using high-precision exposure dating.
iStar-D will identify the potential contribution to sea-level rise, from ice locked in the Amundsen Sea sector of Antarctica
Understanding the contribution that polar ice sheets make to global sea-level rise is recognised internationally as urgent. The mission of this five-year project is to capture new observations and data …

The rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. Stabilisation of the ozone hole along with natural climate variability were significant in bringing about the change. Together these influences have now caused the northern part of the peninsula to enter a temporary cooling phase. Temperatures remain higher than measured during the middle of the 20th Century and glacial retreat is still taking place. However, scientists predict that if greenhouse gas concentrations continue to rise at the current rate, temperatures will increase across the Antarctic Peninsula by several degrees Centigrade by the end of this century.
