The priest speaketh.
Carbon dioxide is the greatest culprit. It is odorless and invisible; for the most part, it does its damage without our awareness. Carbon dioxide and other greenhouse gasses collect in the upper part of the Earth's atmosphere and remain trapped there. When solar radiation passes through the Earth's atmosphere, most of this radiation is absorbed by the earth's surface. However, some of the solar radiation is reflected back to the atmosphere. Odinarily, part of this radiation would continue onward to outer space, and part would be reflected back to earth.The guy was way behind the curve on CO2 in 2004. I'm not convinced of his expertise on something so non-mainstream as low energy nuclear reactions.
However, as a blanket of green house gasses accumulates in the upper atmosphere, it absorbs the wavelengths of reflected radiation and converts it into thermal energy. The gasses remains [sic] trapped, upsetting the delicate energy balance as the Earth makes its yearly journey around the sun, and contributing to an increase in global temperature worldwide.
