For example, aside from solar magnetic activity, the Sun affects the Earth's climate in several other ways, including ultraviolet warming of the upper stratosphere, the nucleation of aerosols, and cloud formation. The climate is also subject to the rate of water vapor exchange between the atmosphere and Earth's surface, which requires taking into account ocean currents, wind, and geography.
Pero la amenaza planteada por el calentamiento global es de todas maneras real y enfocarse en las emisiones humanas de CO
