Water Vapor Causing Climate Warming

karvind writes "According to BBC, new studies suggest that water vapor rather than carbon dioxide in the atmosphere is the main reason why Europe's climate is warming. The scientists say that rising temperatures caused by greenhouse gases are increasing humidity, which in turn amplifies the temperature rise. This is potentially a positive feedback mechanism which could increase the impact of greenhouse gases such as CO2. Even though 2005 will probably be warmest year, climatologists still differ in opinion"

This allows us to draw two important conclusions: 1. Humans are not responsible for global warming. 2. Climatology, a "soft" science, will never be able to provide the kind of reliable conclusions on which to form policy which "hard" scientists, such as libertarian economists, provide. Your two conclusions preclude each other. If the statement "Climatology will never provide reliable conclusions is true, then we cannot conclude that humans are not responsible for global warming, since the the latter conclusion assumes that there is at least one case in the universe of discourse such that Climatology provide us with a valid conclusion x.
