Some of the chemicals that replaced ozone-harming CFCs are long-lived greenhouse gases. At NOAA's lab in Boulder, Colorado, chemist Steve Montzka leads the effort to monitor the concentration of CFC-substitutes and their potential impact on global warming.

In addition to its primary mission of observing space weather, the Deep Space Climate Observatory (DSCOVR) satellite is carrying two instruments that are important to climate science: the NISTAR radiometer and the EPIC camera. 

As sea level has changed, so has the way we measure it. Here’s a look at some of the technologies climate and marine scientists have used to track Earth’s tides and global sea level over the past two centuries.
