Culprits of Climate Change

NASA Marshall Space Flight Center

For many years, researchers agreed that climate change was triggered by "greenhouse gases," with carbon dioxide from burning of fossil playing the biggest role. However, NASA funded scientists suggest that climate change in recent decades has been mainly caused by air pollution containing non-carbon dioxide greenhouse gases.
