Understanding the causes of recent climatic trends and variability in the high-latitude
Southern Hemisphere is hampered by a short instrumental record. Here, we analyse recent …

Over the past 37 years, satellite records show an increase in Antarctic sea ice cover that is
most pronounced in the period of sea ice growth. This trend is dominated by increased sea …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

Abstract On 25 February 2022 Antarctic sea ice extent dropped to a satellite‐era record low
level of 1.92× 106 km2, 0.92× 106 km2 below the long‐term mean. The area of sea ice was …

In stark contrast to the Arctic, there have been statistically significant positive trends in total
Antarctic sea ice extent since 1979. However, the short and highly variable nature of …

Abstract The Antarctic Peninsula (AP) is often described as a region with one of the largest
warming trends on Earth since the 1950s, based on the temperature trend of 0.54° C/decade …

We present an update of the 'key points' from the Antarctic Climate Change and the
Environment (ACCE) report that was published by the Scientific Committee on Antarctic …

To understand how planet Earth works we study it increasingly as a system–a collection of
interdependent parts or spheres–the lithosphere, the hydrosphere, the cryosphere, the …

Here we present Antarctic snow accumulation variability at the regional scale over the past
1000 years. A total of 79 ice core snow accumulation records were gathered and assigned …

The oxidation of dimethyl sulfide (DMS) in the troposphere and subsequent chemical
conversion into sulfur dioxide (SO 2) and methane sulfonic acid (MSA) are key processes for …
