I enjoyed Ronald Kessler’s “Biden’s climate fraud” (Web, Nov. 9), but there’s an elephant in the room worth mentioning. Carbon dioxide particles are present in Earth’s atmosphere at the rate of 419 per million, or .04 percent. But what other particles are present in the atmosphere, in those 999,581 particles per million? In checking, I learned that those particles are water or water vapor at 99.96% of Earth’s atmosphere. It is they — and not the carbon dioxide particles — that actually control the planet’s temperature. I also learned that humankind only contributes a small portion of those 419 parts per million of carbon dioxide.
