For meteorologists acknowledge that our atmosphere is principally heated by surface contact and convective circulation. Surrounded by the vacuum of space, moreover, the earth can only dissipate this energy by radiation. On one hand, then, if surface-heated nitrogen and oxygen do not radiate the thermal energy they acquire, they rob the earth of a means of cooling off — which makes them “greenhouse gases” by definition. On the other hand, though, if surface-heated nitrogen and oxygen do radiate infrared, then they are also “greenhouse gases,” which defeats the premise that only radiation from the infrared-absorbers raises the earth’s temperature. Either way, therefore, the convoluted theory we’ve been going by is wrong.

An idea has been drummed into our heads for decades, that roughly 1% of the atmosphere’s content is responsible for shifting the earth’s surface temperature from inimical to benign. This conjecture has mistakenly focused on specifically light-absorbing gases, however, ignoring heat-absorbing gases altogether. Any heated atmospheric gas radiates infrared energy back toward the earth, meaning that the dreadful power we’ve attributed to light-absorbing molecules up to now has been wildly exaggerated and must be radically adjusted, indeed, pared down perhaps a hundred times. Because all gases radiate the heat they acquire, trace-gas heating theory is an untenable concept, a long-held illusion we’d be wise to abandon.
