A new study led by NASA links anthropogenic climate change to a wide range of effects. The study involved scientists from about a dozen institutions and agencies, and looked at biological impacts arising from global temperature increase since the 1970s. The article is published in Nature. According to lead author Cynthia Rosenweig, “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 impact … 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.From the abstract of the paper: Continue reading Impacts of anthropogenic climate change many, varied
