Greenhouse warming potential (GWP)

• An estimate of how much a molecule of any compound can contribute to global warming over a period of 100 years relative to one molecule of CO2.

• A measure of the amount of heat trapped by a greenhouse gas compared to CO2 over a 20-year period.

• The total amount of carbon dioxide emissions produced by a country in a year.

• A calculation of the energy efficiency of a greenhouse gas in comparison to methane.

Which of the following best describes the primary cause of global ocean warming?

• Increased number of animal species using ocean gyres for migration

• Increased movement from the ocean floor (upwelling) during La Niña events

• Increased thermal pollution in rivers and streams near power plants and industrial manufacturers

• Increased global temperature from an increase in greenhouse gases in the atmosphere

Which of the following best describes how an anthropogenic activity can increase ocean acidification?

• Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.

• A spill from an oil rig in the ocean can have acute toxic effects on fish and other aquatic organisms, which disrupt the aquatic food web.

• Tourist activities in coastal areas increase the concentration of sunscreen in the water, which decreases the photosynthetic rates of aquatic producers and increases the pH of the ocean.

• During and after a major volcanic eruption, large amounts of greenhouse gases, aerosols, and ash are released into the stratosphere, which affects global climate.

Coral bleaching can be hazardous to some fish species because

• decomposition of corals can lead to ocean acidification

• coral reefs provide unique habitats for fish

• the dead corals attract predators that feed on the fish

• the corals are the primary source of O2 in ocean water
