Review of the Greenhouse Effect: For the past few weeks TWTW used presentations by William Happer to discuss the greenhouse effect, which is how certain gases interfere with the loss of electromagnetic energy, particularly in the infrared frequencies, from the surface of the earth into space. The gases that slow the loss of energy (heat), keeping the earth warmer at night than it would be otherwise, are known as greenhouse gases. Starting in 1859, physicist John Tyndall described their influence through a set of experiments. Tyndall recognized that water vapor is the dominant greenhouse gas, and without it land masses would freeze at night, making vegetative growth virtually impossible.
