  • We’ve Been Counting Carbon Dioxide Emissions All Wrong August 27, 2014
    We’ve Been Counting Carbon Dioxide Emissions All Wrong
    All the world’s power plants will put out 300 billion additional tons of carbon dioxide during their lifetimes - a massive amount of carbon dioxide that isn’t taken into account by current schemes to regulate these emissions, according to a study published today (Aug. 26) in the journal Environmental Research Letters. The study is the first to calculate this figure for the world as a whole.We’ve Been Counting Carbon Dioxide Emissions All Wrong

When plants photosynthesize, they use energy from sunlight to turn carbon dioxide from the air into sugars used to live and grow. In doing so, they give off a fluorescent light — a glow that can’t be seen with the naked eye, but that can be seen with the right instruments. More photosynthesis translates into more fluorescence, meaning that the plants are very productive in taking up carbon dioxide. The amount of carbon dioxide taken up by plants is called “gross primary productivity,” and is the largest part of the global carbon cycle.
