Climate variability and human impact in South America during the last 2000 years: synthesis and perspectives from pollen records

An improved understanding of present-day climate variability and change relies on high-quality data sets from the past 2 millennia. Global efforts to model regional climate modes are in the process of being validated against, and integrated with, records of past vegetation change. For South America, however, the full potential of vegetation records for evaluating and improving climate models ha...

Introduction: Integrating high-resolution past climate records for future prediction in the Australasian region

Recognising the challenge of human-induced climate change, the World Meteorological Organization and the United Nations Environment Program established the Intergovernmental Panel on Climate Change (IPCC) in 1988 to assess our understanding of the scientific basis of risk of anthropogenic climate change and opportunities for adaptation and mitigation. Unfortunately, relatively widespread instru...

EOF analysis of three records of sea-ice concentration spanning the last 30 years

[1] Several continuous observational datasets of Artic seaice concentration are currently available that cover the period since the advent of routine satellite observations. We report on a comparison of three sea-ice concentration datasets. These are the National Ice Center charts, and two passive microwave radiometer datasets derived using different approaches: the NASA team and Bootstrap algo...
