Hydrosphere climate system

In its assessment of climate change, the IPCC (1990) identified five hydrosphere-related feedback mechanisms in the climate system likely to be activated by increased greenhouse gas concentrations in the atmosphere. These feedbacks are briefly described below for more detailed discussion of the climate system, refer to Chapter 17. 

We cannot disagree with Stanley (2005) and Stanley et al. (2005) that our planet is a system of integrated components driven by the Earth s internal heat and external energy from the Sun. It is evident that geospheric processes like plate tectonics, volcanism, and the rock cycle are linked to the hydrosphere, atmosphere, climate system, and biosphere, and their interactions form the global processes that we observe. 

The chemistry of the climate system is more than simply air or atmospheric chemistry, but it is to a large extent atmospheric chemistry. The atmosphere is the only reservoir connecting all other reservoirs such as the biosphere (plants), hydrosphere (waters) and pedosphere (soils). As chemistry is the science of matter, we consider substances moving through the climate system. We have already mentioned that elementary chemical reactions are absolutely described by a mechanism and a kinetic law and, therefore, are applicable to all regimes in nature if the conditions (temperature, radiation, pressure, concentration) for this reaction correspond to those of the natural reservoir. For example, the photolytic decay of molecules is only possible in the presence of adequate radiation. Hence, in darkness there is no... 

In his book, Detlev Moller gives a thorough overview of the main chemical processes that occur in the atmosphere, only a few of which have been mentioned above. The novel title of this book chemistry of the climate system should direct the attention of the reader to the fact that understanding atmospheric chemistry is incomplete without considering interfacing neighboring reservoirs such as the hydrosphere, the lithosphere and the biosphere.
