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.

Today, delivering on a commitment in the President's Climate Action Plan, the Administration launched the Climate Data Initiative. This new effort brings together open government data and design competitions with commitments from the private and philanthropic sectors to develop data-driven tools that communities across America need to plan for the impacts of climate change.

What does the future of climate look like where you live? For the first time, maps and summaries of temperature and precipitation projections for the 21st century are accessible at a county-by-county level, thanks to a website developed by the U.S. Geological Survey (USGS) in collaboration with the College of Earth, Oceanic and Atmospheric Sciences at Oregon State University.
