Future changes in the boreal polar vortex under a climate change scenario are still a matter of debate in the scientific community. For example, there is a lack of consensus among models about possible future changes in the frequency of major stratospheric warmings.
The decrease of atmospheric CO2 concentration recorded in Antarctic ice around 1600 AD is one of the mostsignificant atmospheric changes to have occurred during the last millennia, before the onset of the industrial period.Together with the temperature decrease…
During the last deglaciation (21,000 to 7,000 years ago) global sea level rise was punctuated by several abruptmeltwater spikes triggered by the retreat of ice sheets and glaciers world-wide. However, questions regarding therelative timing…
Southern Hemisphere climate reconstructions are limited by quantity and spatial coverage of well resolved paleoclimaterecords from the last 2000 years. This was the motivation to drill an ice core at a new site in East Antarctica…
The 2015 ozone hole only started developing during the third week of August, which is the latest onset of the ozone hole that has been seen since the mid-to-late 1980s. However…
Aerosol observations above the Southern Ocean and Antarctic sea ice are scarce. Measurements of aerosols and atmospheric composition were made in East Antarctic pack ice on-board the Australian icebreaker Aurora Australis during the spring of 2012.
