The changes precipitated by the accumulation of greenhouse gases within the global environment are not limited to change in temperature, but are, in fact, many and diverse. The overarching range of effects that are a direct result of increased concentrations of greenhouse gases is referred to as climate change. It appears that certain changes in the world's oceans are directly related to climate change. We have already examined some of these influences including the rise in temperature and the increasing acidity of the world's oceans.
In a recent report from the laboratory of Dr. I.R. Young and his colleagues from the Swinburne University of Technology at Melbourne, Victoria, Australia, it has been established that there is a trend towards increases in oceanic wind speed and wave height. These findings are based on satellite-derived data using a variety of measuring devices including altimeters, sophisticated radar equipment, etc. The advantage of using this type of instrumentation is that the scope of investigation is global in scale.
Oceanic wind speed and wave height are involved in the maintenance of the flow of energy from the atmosphere to the ocean and are involved in upper-ocean mixing. In the analysis of the data, Young and his associates used a database that contained information collected over a twenty-three year interim. The authors of this study caution that on account of the relatively brief interval of time encompassed by these data, they cannot determine if this trend will continue to increase or accelerate into the future.
On account of the importance of these changes in terms of their possible impact on the global climate system, it would be judicious to extend the lifetime of this kind of study into the future.
