Group A Renewable EnergyElectrical demand in California is largest on hot and humid days when people turn on air conditioning. Are solar power and wind power also large on hot and humid days?

  • Fossil fuels are the primary energy source for generation of electrical power. Even though they cause air pollution, global warming, and ocean acidification, fossil fuels are used because they can be burned at any time that they are needed. Renewable energy sources like solar power and wind power are much more environmentally friendly, but they are not used so much to generate electrical power because they are only available when the sun is shining and the wind is blowing. It would be more worthwhile to invest in solar power and wind power if we knew they would be most available at the times when electrical demand is greatest.

Group B Cooking EmissionsHow do the amount/types of aerosol particles produced differ when cooking meat or vegetables over a charcoal or propane flame?

  • “Economic conditions force billions of people to burn biomass such as wood, charcoal, and dung to cook their food. These fires emit black carbon (a major component of soot), ozone- producing gases, methane and numerous other gases and particles that pollute the air. The soot from indoor smoke ultimately escapes to the outdoors and combines with other outdoor air pollution (fossil fuel combustion) to form atmospheric brown clouds (ABCs). ABCs contain sulfates, nitrates, soot and fly ash among many other pollutants. Soot and other particles in ABCs lead to a large reduction of sunlight at the ground and in addition lead to large atmospheric solar heating. The atmospheric solar heating by soot, next to carbon dioxide (CO2), is the major contributor to global warming.”

Group C AcidificationAt what acidity level would impede brine shrimp nauplii from developing?Baby brine shrimp first free- swimming period it is called a nauplius (plural: nauplii).

  • Fossil fuels are the primary energy source for us, but along with this use they cause air pollution, global warming, and ocean acidification because they can be burned at any time that they are needed. The unfortunate result has been the emission of carbon dioxide in the order of billions of tons and about half is absorbed by the oceans over time. While this process benefited us in mitigating greenhouse effect, the fact remains that this massive load of carbon dioxide is altering water chemistry and afflicting damage to the life cycle of many marine organisms. Many of the invertebrates and phytoplankton in the lower food chain have casings that comprised of calcium carbonate, therefore they are susceptible to the effects of acidification and primary production.

Group D TemperatureHow would acute increase in temperature affect the respiratory rate and ammonia production in fish?

  • Massive fish die-offs due to stretches of warm weather that are sometimes coupled with algal blooms are not unusual in stagnant areas of the tropical seas. However, finding this event in subtropical regions is disturbing as in several recent massive die-offs. With increasing signs of global warming, the acute rise in temperature on small bodies of water may become a more frequent occurrence.

  • A multitude of factors affect the survival of fish. Oxygen and temperature levels are pivotal influences on a fish’s life.  Fish, being ectothermic, bear a strong reliance on its surrounding temperature.  Metabolism increases proportionately with temperature. Hence, in warmer temperatures, fish tend to be more active and consume more oxygen, while under cooler temperatures the opposite is true.  Consequently, temperature changes can have a strong influence on fish survival.

Group E SalinityHow would changes in salinity affect the mortality of an intertidal and estuarine vertebrate.

  • Osmoregulation is am important physiological process in maintaining optimal slat and water balance between the organism and the environment. Aquatic animals subjected to fluctuations in salinities, such as estuarine, brackish, and intertidal zones, are constantly under stress. Records drawn from National Oceanographic Data Center between 1955 to 2004 showed changes in the oceans salinity spanning from 60 degree North to 60 degree South. These shifts were consistent with anthropogenic effects influencing the long term change in the hydrological cycle. As such, the added magnitude of stress imposed on these animals may be greatly amplified by climate change thereby may compromise their ability to osmoregulate.
