Paleoclimate records are studied to understand Earth's past climate. What are some ways of measure our past climate?

• Mineral deposits in deep-sea beds

• Chemical variations in coral reefs

• Ocean bouys and satellites

• Both A and B

• All of the above

Answer explanation

Ocean buoys and satellites help us track current temperatures, but they can’t tell us what temperatures were like in the past.

During a global warming period, global ocean levels are projected to increase because of ______________.

• Extreme weather events

• Melting glaciers and ice sheets

• Water retained in the atmosphere being released

• All of the above

Answer explanation

Sea level rise happens when glaciers and ice sheets melt, adding more water to the ocean.

In a reverse scenario, if the climate cooled and more glaciers and ice sheets formed, sea levels would actually decrease.

The Eocene increase happened over tens of millions of years, while today’s CO₂ is rising over just hundreds of years.

• True

• False

As atmospheric CO₂ increases, what will happen to CO₂ in the ocean, and why is CO₂ considered the most important greenhouse gas?

• Ocean CO₂ will decrease; CO₂ is the only greenhouse gas that affects the greenhouse effect

• Ocean CO₂ will increase; CO₂ is emitted in far larger quantities than other greenhouse gases

• No change in ocean CO₂; CO₂ is not a naturally occurring gas and is more dangerous

• Ocean CO₂ will increase; CO₂ is not considered the most important greenhouse gas
