The National Oceanic and Atmospheric Administration (NOAA) recently released two reports that provide detailed comparisons of phases 3 and 5 of the Coupled Model Intercomparison Project (CMIP3 and CMIP5) for the United States. Understanding the strengths of these simulations and the differences among models is important for sustained assessment

New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of carbon tetrachloride (CC14), an ozone -depleting chemical that was banned worldwide decades ago. According to the study, global emissions of CCl4 average 39 kilotons per year—approximately 30 percent of peak emissions prior to its banning.
