Climate Change Amplify

What would happen to energy in the Earth system if the atmosphere had less methane?Energy in the Earth system would

• decrease, because less energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.

• decrease, because more energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.

• decrease, because less energy would enter than exit. This is because less energy would be trapped by gases and held in the atmosphere.

• increase, because more energy would enter than exit. This is because less energy from the sun would beredirected (bounced) back toward outer space.

Some scientists found that millions of years ago, there was a time when the number of trees increased very quickly, leading to a decrease in the amount of carbon dioxide in the atmosphere. What would you predict about the amount of energy absorbed by Earth's surface during this time?

During this time, the amount of energy absorbed by Earth’s surface

• increased.

• decreased.

• stayed at a consistent level.

• changed unpredictably.

Scientists have tools that measure the amount of energy entering and exiting the Earth system. Recently, more energy entered the system than exited. What might scientists expect to see in the atmosphere, and what has changed about energy in the Earth system?

• Methane decreased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.

• Methane decreased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.

• Methane increased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.

• Methane increased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.

Fossilized shells from the Pacific Ocean show that about 15 million years ago, there was a time period when carbon dioxide in the atmosphere increased. What would have happened to the energy absorbed by Earth’s surface during this time?

During this time, energy absorbed by Earth’s surface

• stayed at a constant level.

• changed unpredictably.

• decreased.

• increased.

A climatologist is creating a simulation for Earth’s climate and is working on how to set it up. One of the options for the simulation is to increase methane in the atmosphere. How should the energy in the Earth system change when the amount of methane in the atmosphere increases?

• more energy in the Earth system and more energy absorbed by Earth’s surface, because less energy enters than exits.

• more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy enters than exits.

• less energy in the Earth system and less energy absorbed by Earth’s surface, because more energy enters than exits.

• less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy enters than exits.

From about 120 to 80 million years ago, scientists think that a large amount of carbon dioxide was released from rock on the ocean floor, which led to increased carbon dioxide in the atmosphere. What happened to energy in the Earth system during this time?

• increased, because less energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.

• increased, because more energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.

• increased, because more energy entered than exited. This is because more energy was trapped by gases and held in the atmosphere.

• decreased, because less energy entered than exited. This is because more energy from the sun was redirected (bounced) back toward outer space.

A climatologist was working with a computer simulation that models Earth’s climate and atmosphere. She set up the controls of the simulation to decrease the amount of methane in the atmosphere. What should happen to the amount of energy absorbed by Earth’s surface?

When methane decreases, the amount of energy absorbed by Earth’s surface should

• change unpredictably.

• stay at a constant level.

• increase.

• decrease.

How does climate change amplify the greenhouse effect?

• By increasing the concentration of greenhouse gases in the atmosphere

• By decreasing the concentration of greenhouse gases in the atmosphere

• By reducing the Earth's surface temperature

• By increasing the Earth's albedo

What role do feedback loops play in climate change amplification?

• They stabilize the climate system

• They amplify changes in the climate system

• They have no effect on the climate system

• They reverse climate change effects
