Climatic interpretation of high-resolution chemistry and dust data from East Antarctica
Climate change has become real. Extreme weather events like floods, draughts and hurricanes have gripped peoples and the media’s attention and have been put in relation with rising greenhouse gas concentrations and deforestation. Desertification and extinction of species are now monitored and altern...

Climate change has become real. Extreme weather events like floods, draughts and hurricanes have gripped peoples and the media’s attention and have been put in relation with rising greenhouse gas concentrations and deforestation. Desertification and extinction of species are now monitored and alternative energy production has become a profitablemarket. These signs show that people all over the world have accepted climate changeas a reality and are prepared to adapt. The question of how to adapt and what to do hasnaturally arisen. This year’s Intergovernmental Panel on Climate Change (IPCC) report predicts a global mean temperature rise of up to 4◦C until the end of the century [IPCC, 2007b] and describes the possible effects on human population, industry and geosphere [IPCC, 2007a].
