Trenberth argues that since science / physics has already established the human influence on climate, oceans, etc. (and Curry would not say otherwise) it makes more sense for Curry to have to show that there is no influence on water vapor and precipitation (i.e., intensification of storm activity / heavy precipitation) than to show that there is, because of basic physics / physical systems / physical relationships that constitute the global climate cycle.

On the question of hurricanes, the theoretical arguments that more energy and water vapor in the atmosphere should lead to stronger storms are really sound (after all, storm intensity increases going from pole toward equator), but determining precisely how human influences (so including GHGs [greenhouse gases] and aerosols, and land cover change) should be changing hurricanes in a system where there are natural external (solar and volcanoes) and internal (e.g., ENSO, NAO [El Nino - Southern Oscillation, North Atlantic Oscillation]-RRB- influences is quite problematic — our climate models are just not good enough yet to carry out the types of sensitivity tests that have been done using limited area hurricane models run for relatively short times.
