Climatology of Greater St. Lucia Wetland Park... HELP PLEASE?
-what evidence is there to suppoet these changes?
-what is global warming? and how will it affect the wetland?
-how, if possible can this area reduce global warming?
Answer:
CHanges: This system has recently experienced the stress of a 2-year drought, where the mouth has remained closed for 18 months with extreme hypersaline conditions developing in the upper reaches.
Evidence:
The hypersaline conditions (70-90‰) that developed in the northern part of the estuarine system in 1970 as a direct result of the drought, led to a number of extraordinary changes in some of the basic trophic relations. These involved mainly: a) the formation of red, potentially toxic dinoflagellate blooms (Grindley & Heydorn 1970); b) the dominance of chironomid larvae and harpacticoid copepods in bentho-pelagic samples (Grindley 1982); and c) a plague of swarming chironomid midges followed by a population explosion of aerial spiders in response to the availability of midge preys.

the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.
The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect. Visible, shortwave light comes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases composed largely of water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Infrared radiation reflects off the planet's surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward, keeping the planet at an average temperature suitable to life, about 60°F (16°C).
how to reduce global warming-Improved automobile mileage, reforestation projects, energy efficiency in construction, and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S. production of greenhouse gases. More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels, the elimination of chlorofluorocarbons, and the slowing of deforestation by restructuring the economies of developing nations. In 2002 the Bush administration proposed several voluntary measures for slowing the increase in, instead of reducing, emissions of greenhouses gases.
This area in particular could reduce global warming by reducing ecotourism, which is a big industry in that part of the world.
