• Resumen

  • The article discusses a controlled experiment investigating climate change which was conducted at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory. Scientists carefully manipulated grasslands and forests to determine how the biosphere is affected by changes in precipitation, temperature, and carbon dioxide (CO2). An in-depth discussion of each variable and its corresponding experiment is presented.
