Antarctica has experienced major changes in temperature, wind speed and stratospheric ozone levels over the last 50 years. Whilst West Antarctica and the peninsula have shown rapid warming and consequent ecosystem change, East Antarctica appeared to be little impacted by climate warming…
Missing gravity wave drag near 60 degrees south has been proposed as the cause of the common cold bias in modelled southern polar stratospheric temperatures [McLandress et al. 2012]. Potential gravity wave momentum sources around those latitudes, such as jets…
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.
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…

Polar communities are expected to experience the impacts of ocean acidification sooner and more heavily than other regions, and serve as indicators of the consequences we can expect from increasing ocean CO2 concentrations.
