On Earth Day: Carbon Dioxide and Climate – Friend or Foe?

Is CO2 really the bogeyman? Is it a friend or foe of planet Earth? The answer may surprise you.

As the climate has modestly warmed, U.S. crop yields have set new records almost every year. The same is true for nearly all other nations, too. Thanks in large part to longer growing seasons, fewer frost events, more precipitation, and the fertilization effect of atmospheric carbon dioxide, farmers are producing greater amounts of food on fewer acres of land, allowing them to feed the world’s growing population.
