Data from the Pioneer spacecraft of NASA apparently prove the theory that the high surface temperature of Venus is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet’s atmosphere, warms its surface, and is converted to heat radiation that is then held in by the atmosphere from top to bottom. Venus has a relatively thin atmosphere like the Earth’s, but Venus’ atmosphere consists of more than ninety percent carbon dioxide, compared to less than four percent in that of the Earth. Because of its higher percentage of carbon dioxide, Venus’ atmosphere traps much more heat radiation than does the Earth’s. Thus, the Venus studies are believed to be important to the understanding of possible adverse effects on the Earth’s agriculture that could result from the long-term use of fossil fuels, which add carbon dioxide to the atmosphere.
