A “greenhouse gas” is one capable of absorbing infra-red (IR) radiation.
The most common atmospheric gases with such properties are water vapour and carbon dioxide (CO2). Water vapour is far more abundant with an average of 20,000 parts-per-million (ppm) in the atmosphere compared to just 395 ppm of CO2. Moreover water vapour is more effective as a greenhouse gas because it can absorb IR radiation over far more bands of the IR spectrum.
Therefore, if man-made CO2 causes dangerous global warming, (a dubious proposition anyway), then man-made water vapour is far more dangerous. Continue Reading →
