What is its role in global climate change?
The NOAA ESRL GMD Carbon Cycle-Greenhouse Gases group (CCGG) conducts research to understand the global carbon cycle and its effects on climate. At CCGG measurements are made to determine baseline levels, trends and causes of variability of several atmospheric gases (carbon dioxide, methane and carbon monoxide), that have the potential to affect global climate. To obtain detailed understanding of the short term as well as long term variations of the greenhouse gases, CCGG makes on-site measurements at the four NOAA/CMDL baseline observatories, which are far from any pollution sources affecting the gases of interest.
