Climate science: Tree rings and storm tracks
TLDR
In this paper, an analysis of tree-ring records suggests that recent changes in the southern storm track in summer are unprecedented in the past 600 years, and that the Southern Hemisphere is a challenging region to reconstructing past climate.Abstract:
Reconstructing past climate in the Southern Hemisphere is a challenge. An analysis of tree-ring records suggests that recent changes in the southern storm track in summer are unprecedented in the past 600 years.read more

Not just about sunburn – the ozone hole's profound effect on climate has significant implications for Southern Hemisphere ecosystems
TL;DR: The objective of this synthesis was to stimulate the ecological community to look beyond ultraviolet-B radiation when considering the impacts of ozone depletion, as widespread changes in Southern Hemisphere climate are likely to have had as much or more impact on natural ecosystems and food production over the past few decades.

Assessing the dendroclimatic potential of Nothofagus betuloides (Magellan’s beech) forests in the southernmost Chilean Patagonia
TL;DR: In this article, the authors presented six new Magellan's beech tree-ring width (TRW) chronologies, spanning between 202 and 500 years, developed from southernmost Patagonia (>50°S), Chile.

Evaluation of tree-ring archive as paleoclimatic tracer in northern Patagonia
TL;DR: In this paper, the authors analyzed the temporal variations of the width and of the oxygen and carbon isotopic compositions of the cellulose of two native species (Fitzroya cupressoides and Nothofagus pumilio) in northern Patagonia (41°S, Argentina) by analyzing their different physical tree-ring parameters.

The Antarctic Centennial Oscillation: A Natural Paleoclimate Cycle in the Southern Hemisphere That Influences Global Temperature
TL;DR: A previously-unexplored natural temperature cycle recorded in ice cores from Antarctica, the Antarctic Centennial Oscillation (ACO), has oscillated for at least the last 226 millennia as mentioned in this paper.

Climate change-induced water shortages: improving decision-making in an uncertain future
TL;DR: In this article, an approach to translating probabilistic UKCP09 weather generator information into a usable and replicable risk-based climate change impacts assessment and a basis for robust adaptation planning in the England and Wales water sector is described.

Simulation of recent southern hemisphere climate change.
TL;DR: The results provide evidence that anthropogenic emissions of ozonedepleting gases have had a distinct impact on climate not only at stratospheric levels but at Earth's surface as well.

Stratospheric Ozone Depletion: The Main Driver of Twentieth-Century Atmospheric Circulation Changes in the Southern Hemisphere
TL;DR: In this article, the importance of stratospheric ozone depletion on the atmospheric circulation of the troposphere is studied with an atmospheric general circulation model, the Community Atmospheric Model, version 3 (CAM3), for the second half of the twentieth century.

The Impact of a Changing Southern Hemisphere Annular Mode on Antarctic Peninsula Summer Temperatures
TL;DR: In this paper, the Southern Hemisphere Annular Mode (SAM) has exhibited a marked trend, suggested by modeling studies to be predominantly a response to anthropogenic forcing, resulting in increased westerlies across the northern peninsula.

TL;DR: In this article, the authors used tree-ring records from over 3,000 trees in South America, Tasmania and New Zealand to identify dominant patterns of tree growth in recent centuries and showed that the foremost patterns of growth between 1950 and 2000 differed significantly from those in the previous 250 years.
