• faster melting of global polar ice caps

• stable atmospheric humidity

• decreased global surface temperatures

Describe the CO2 levels in the atmosphere over the past ~ 30 years.

• CO2 levels have had no substantial change

• CO2 levels are steadily increasing

• CO2 levels are decreasing

• CO2 levels are all over the place! Sharp spikes up and down!

Is there a relationship between CO2 levels in the atmosphere and ocean surface temperature?

• No; CO2 has no effect on global temperatures

• Yes; CO2 levels contribute to a decrease in ocean temperatures

• Yes; CO2 levels contribute to an increase in ocean temperatures

• No; the oceans are too big to be affected by the atmosphere

Carbon dioxide is called a greenhouse gas for which of the following reasons?

• It absorbs and radiates infrared radiation to warm the Earth.

• It is produced when coal and/or fossil fuels are burned.

• It is often used inside greenhouses.

• Its oxygen component is needed by plants to grow.

How would rising ocean surface temperatures affect hurricanes?

• Hotter oceans create fewer hurricane, but those that exist are stronger

• Hotter oceans have no effect on hurricanes

• Hotter oceans create more hurricanes and stronger hurricanes

• Hotter oceans create fewer hurricanes and those that exist are much weaker

Which of the following is a short-term cause of climate fluctuation?

• Solar Activity

• Carbon Monoxide

• Milankovich Cycles

• El Nino

El Niño weather events are determined by

• the amount of gases that volcanoes create each year on the seafloor near Australia.

• changes in winds and currents of the Pacific Ocean near the equator

• a decrease in the frozen glaciers at Earth's poles.

• the magnetic strength of Earth's inner core.

Based on the graph, which hypothesis is correct?

• Volcanic eruptions permanently raise temperatures in the Northern Hemisphere after an eruption.

• Volcanic eruptions cause a decrease in temperatures in the Northern Hemisphere after an eruption.

• Volcanic eruptions cause an increase in temperatures in the Northern Hemisphere after an eruption.

• Volcanic eruptions permanently lower temperatures in the Northern Hemisphere after an eruption.

Which of the following best describes the Earth's average surface temperature over long time scales?

• a steady warming trend

• fairly steady temperatures until recently

• several periods of cooling and warming

• fairly steady with occasional cool spells

• fairly steady with a recent cooling trend
