Page 2 of 2 The NASA-led researchers concluded, “Given the conclusions from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report that most of the observed increase in global average temperatures since the mid-twentieth century is very likely to be due to the observed increase in anthropogenic greenhouse gas concentrations, and furthermore that it is likely that there has been significant anthropogenic [caused by humans] warming over the past 50 years averaged over each continent except Antarctica, we conclude that anthropogenic climate change is having a significant impact on physical and biological systems globally and in some continents.” Rosenzweig stated, "This is the first study to link global temperature data sets, climate model results, and observed changes in a broad range of physical and biological systems to show the link between humans, climate, and impacts.” [NASA Earth Observatory: “Earth impacts linked to human-caused climate change”] She also said, "Humans are influencing climate through increasing greenhouse gas emissions and the warming is causing impacts on physical and biological systems that are now attributable at the global scale and in North America, Europe, and Asia.” Rosenzweig was joined in the research study by scientists from ten other organizations from Australia, the United States, Chile, Germany, France, Poland, China, Trinadad and Tobago, and the Netherlands. These scientists include David Karoly (University of Melbourne, Australia), Marta Vicarelli (Goddard Institute for Space Studies and Columbia Center for Climate Systems Research), Peter Neofotis (Goddard Institute for Space Studies and Columbia Center for Climate Systems Research), Qigang Wu (University of Oklahoma, U.S.A.), Gino Casassa (Centro de Estudios Cientificos, Chile), Annette Menzel (Technical University of Munich, Germany), Terry L. Root (Stanford University, U.S.A.), Nicole Estrella (Technical University of Munich, Germany), Bernard Seguin (INRA Unité Agroclim, France), Piotr Tryjanowski (Institute of Environmental Biology, Poland), Chunzhen Liu (China Water Information Center, China), Samuel Rawlins (Caribbean Epidemiology Center, Trinadad and Tobago), and Anton Imeson (3D-Environmental Change, Netherlands).
