Word of the day: greenhouse effect (noun) An atmospheric heating phenomenon, caused by short-wave solar radiation being readily transmitted inward through the earth's atmosphere but longer-wavelength heat radiation less readily transmitted outward, owing to its absorption by atmospheric carbon dioxide, water vapor, methane, and other gases; thus, the rising level of carbon dioxide is viewed with concern.
Why is it that people only complain about global warming (or a perceived lack there-of) when it's 20 degrees and windy in July but have no problem with global warming when it's 15 degrees in December?
