"In 1983, the concentration of carbon dioxide in the atmosphere was about 343 parts per million. The global average temperature was around 0.3 degrees Celsius higher than before the Industrial Revolution. And the U.S. EPA sounded an alarm about global warming. Four decades later, with carbon dioxide eclipsing 420 ppm and average warming up to around 1.2 degrees Celsius, it's worth looking back to see just how well some of the EPA’s projections hold up."
