	1.-		Air pollution increases acid rain and degrades the atmospheric ozone that protects the earth from ultraviolet (UV) radiation. How does this impact lake water quality?


	2.-		Are cyanobacteria a year-round problem in water supplies?


	3.-		Aren't other factors beside human activities responsible for global warming?


	4.-		As part of the earth's total hydrologic cycle how can evaporation and transpiration from land sources exceed what comes to a given area by rainfall when these areas are not impacted by humans?


	5.-		As part of the earth's total hydrologic cycle how many inches of water evaporates from the earth's oceans each year?


	6.-		As part of the earth's total hydrologic cycle how much water evaporates from the earth's land surface each year?


	7.-		As part of the earth's total hydrologic cycle how much water evaporates from the earth's oceans each year?


	8.-		As part of the earth's total hydrologic cycle how much water returns to the earth's land surface each year as precipitation?


	9.-		Can a gradual warming of the earth affect water pollution associated with blue-green algae, also known as cyanobacteria?


	10.-		Can climate change impact the formation of acidic water problems?


	11.-		Can greenhouse warming affect availability of surface water resources within some areas of the United States?


	12.-		Can human activities have an impact on ice particles in clouds, and thus impact the earth�s overall temperature?


	13.-		Can land-based farming methods that increase organic matter in soils benefit agriculture productivity and water quality?


	14.-		Can lightning in the atmosphere produce nitrate nitrogen that is then brought down in rainfall?


	15.-		Can you get a blue-green algae bloom in winter?


	16.-		Do all tropical marine areas and coral reefs in such areas contain toxins from ciguatera?


	17.-		Do water particles in the atmosphere simply change to ice when the surrounding temperature reaches freezing?


	18.-		Does El Ni�o have anything to do with global warming and climate change?


	19.-		Does harvesting trees worsen the "greenhouse effect" which can impact water quality and the water cycle?


	20.-		Does increased sequestering of atmospheric CO2 in the oceans impact ocean ecology?


	21.-		Does ozone layer depletion have anything to do with global warming and climate change?


	22.-		Does water have unique thermal properties?


	23.-		Has atmospheric pollution from leaded gasoline had an impact on delaying global warming from the increased carbon dioxide emissions from burning fossil fuels?


	24.-		How can radar be used to determine the amount of rain in an approaching storm?


	25.-		How can sea organisms affect global climate?


	26.-		How can we talk about climate change over the next 100 years when we can't be sure of tomorrow's weather?


	27.-		How could global warming impact surface fresh water systems?


	28.-		How do climate, snow, and ice affect the water resources in the northern reaches of our continent?


	29.-		How do we know CO2 in the atmosphere is increasing and that humans are responsible?


	30.-		How does global warming impact recreational uses of water?
