Climatic Change and Water Balance Techniques - Essay Example

1. It is important to:
2. To analyze fluctuations in Deficit and AET between previous (1700), present (from 1971 to 2000), and future (from 2020 to 2049) climatological methods obtained from observations, forecasts, and proxies (Lutz, Wagtendonk & Franklin, 2010).
3. To conclude how the scale of fluctuating deficit could affect changes in forest composition and contour (Lutz, Wagtendonk & Franklin, 2010).

The author employed a variation of the Thornwaite-type technique, as well as correlated AET and Deficit supported by tree species distribution. The data used is primary because it was collected and analyzed by the authors, and not mined from some other sources. Temporal analysis is used on a moderate scale, and the analytical method used is plotted (Lutz, Wagtendonk, & Franklin, 2010). The author uses plots to analyze the data and to represent the data sets. The author plots the data sets as graphs depicting the correlation between multiple sets of data.

Results
The authors computed species' climatic envelopes in wide ranges of climatic gradients. They also distinguished tree species using Deficit and AET. For all species, modeled Deficits grew by an average of 5% from past and present, while forecasted growth in Deficit from present and future were found to be 23% in all plots (Lutz, Wagtendonk & Franklin, 2010).

My Own Evaluation of the Article
The authors have answered the hypothesis by providing sound analyses and evidence to meet the aims (Lutz, Wagtendonk & Franklin, 2010). The authors also discuss further studies in the areas of topographic scale distributions of aquatic balance, potential impacts of climate change situations, the scale of vegetation change, the sensitivity of plant and animal species, and the downscaling problem (Lutz, Wagtendonk & Franklin, 2010). What I find most interesting is the analyses conducted on AET and PET. Read More
