Without such a theory it is impossible to predict changes in atmospheric circulation, it is impossible to predict changes in the hydrological cycle, it is impossible to predict storm frequencies, intensities and tracks. Future climate cannot be predicted without a theory explaining how climate works, yet the IPCC has confidently made predictions regarding changes in storms, precipitation and climate for decades, even centuries into the future. If something as seemingly simple as water vapor can have such complex and bewildering impacts on Earth's climate why does the IPCC and the climate crisis crowd continue to insist that all fault lies with CO 2 ? It could be that even they realize that blaming global warming on water vapor would give them no political leverage. After all, 70% of our planet's surface is covered with water and not even the most wild-eyed geoengineering proponent would propose we attempt to control the amount of water vapor in the atmosphere.
