Base cations are mobilized by weathering and cation exchange reactions that neutralize acids in the watershed. They respond therefore indirectly to changes in sulphate and nitrate concentrations. In fact, if acid anion concentrations (mainly sulphate) decrease, base cations are also expected to decrease. However, in the last few years an increase of the occurrence of alkaline rain episodes (probably due to climatic effects) has been observed and it is likely that calcareous Saharan dust, rich in base cations, is responsible for it [27]. Accelerated weathering, resulting from recent climate warming may also contribute to higher base cation concentrations [28].

A great variety of possible chemical and climatic effects of aircraft have been investigated in recent years. In this study, aircraft-induced changes in NOy, H20 and ozone have been calculated. The study has contributed to the IPCC report on the atmospheric effects of aviation, which gives a comprehensive introduction into the aircraft issue [3]. 

Much of what is currently known about the Earth s climate comes from the application of stable isotopes collected from ocean drill cores in marine sediments (e.g., Zachos et al. 2001). These isotopic data sets provide detailed records of how the Earth s oceans have responded to changing climate and are extremely valuable in assessing global climate histories down to millennial scales. Similar detailed isotopic records for terrestrial systems are, however, uncommon and frequently continuous terrestrial climate records that span millions to tens of millions of years are not preserved in the terrestrial geologic record. With the advent of paleoaltimetry studies targeted directly at the coupled isotopic effects of changes in climate... 

In addition to long-term and large-scale climatic effects, the annual variation in weather conditions also affected the amount and turnover of plant residues and thus the chemical composition SOM sampled at a certain date (Leinweber et al., 1994, 1995). Figure 14.19 shows the ion intensities for carbohydrates in two plots of the Eternal Rye Cultivation experiment at Halle, Saxony-Anhalt, Germany. In 1958, parts of the former rye monoculture were shifted into maize monoculture. This resulted in decreases in the ion intensities for carbohydrates. In the plot that remained under rye monoculture the ion intensities for carbohydrates increased initially. For several time periods, the changes in ion intensities were roughly parallel for the two plots, which is considered as evidence for annual variations in the decomposition dynamics. For some time (1993 to 1997), there was no significant difference between the rye and maize plots in the ion intensities for carbohydrates, but the... 

Global Warming An increase in the near-surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to a theory that warming occurs as a result of increased use of hydrocarbon fuels by man. See Climate Change (Greenhouse Effect). ...

The ratio of certain stable isotopes, principally 13C/12C and 180/160, varies with geographical location where climatic effects change the proportions of the isotopes available to plants. Stable isotope measurements can be carried out...
