  • LETTERS TO THE EDITOR

  • Gordon Dickerson (Aug. 4) used a Wall Street Journal article by Happer and Schmidt to support climate change denial with no climate scientist, chemist or biologist contributing. Anyone with a brain tumor would consult a neurologist, not a cardiologist. However good the cardiologist might be at heart issues, he/she would not be a good source for brain advice.

    Unsurprisingly, Dickerson's authors present ideas about carbon dioxide that are distortions, naïve or just ignorant. In a greenhouse, where all other nutrients are abundant, carbon dioxide might increase plant growth, but in the real world it's potassium, nitrogen and phosphorous that are critical; this is why fertilizers contain N-P-K.
    However important an element is, we can get too much — with destructive consequences. All life needs salt, but flood a freshwater lake with seawater and we know what happens; a disastrous outcome. Our warming climate comes from burning fossil fuels — Dickerson's market is failing us.
    Snake-oil salesmen used to travel widely plying their "cure for everything that ails you" scam. If we wish to protect the planet for future generations, we have to ignore snake oil salesmen who profit by plying climate denial — and take steps to control carbon dioxide emissions. — Alan Journet, Jacksonville
