<p>[quote user="erikem"]Warming seems to come as fast as cooling, but temperatures seem to bump up against a strong limiting effect most likely due to large tropical thundershowers (tops on the order of 60,000' or so). The latter is important as water vapor is a much larger source of the "greenhouse effect" than CO2, in part because it is a polar molecule.[/quote]</p> <p>The greenhouse effect of water vapor as a natural phenomena is limited as the atmosphere accumulates only a limited amount depending on temperature.</p> <p>On the other hand the CO2 content in the atmosphere has risen by 35% since industrialization began.</p> <p>Water vapor plays a role in manmade warming too as higher temperatures allow higher amounts to be accumulated in the atmosphere strengthening global warming.</p> <p>These effects are included in the climate prognose models.<br />Regards, Volker</p>
