Studies including Wang's earlier work in Africa have shown that even small changes in soil moisture in drylands could be significant enough to cause large changes in vegetation productivity.

So if you think of going in [a] warming direction of 2 degrees C compared to a cooling direction of 5 degrees C, one can say that we might be changing the Earth, you know, like 40 percent of the kind of change that went on between the Ice Age; and now are going back in time and so a 2 - degree change, which is about 4 degrees F on a global average, is going to be very significant in terms of change in the distribution of vegetation, change in the kind of climate zones in certain areas, wind patterns can change, so where rainfall happens is going to shift.

Besides the increased emissions of N2O, the authors observed significant increases in the seasonal release of CO2 and CH4 as a result of only a mild temperature increase, and dug deeply into the reason behind the observed changes by detailed soil and vegetation measurements.

With respect to why there was a significant increase in tree density over the past several decades, Dolanc offers that the changes in the density and composition of lower - elevation forests are consistent with fire suppression; but that the density increases in high - elevation vegetation types (subalpine forests generally don't burn) are «more likely to be caused by changing climate.»

A significant component of this key ecosystem characteristic is dependent on relatively slow processes such as rates of recuitment, mortality, and changes in vegetation composition.

These moist enthalpy - related studies confirm previous results showing that changes in vegetation cover, surface moisture and energy fluxes generally lead to significant climatic changes (e.g. 41 - 43) and responses which can be of a similar magnitude to that projected for future greenhouse gas concentrations (44, 45).
