Question

Fill in the blank. ________ feedback can lead to global warming or global cooling and is related to polar ice caps and glaciers. The reverse of the ice-albedo feedback is an increase in _______. _______ water increases the rate at which carbon dioxide can be dissolved inside the ocean. If a certain climate change process has ________ radiative forcing, one would expect that this would increase temperature. Blackbody radiation is one example of ________ feedback in Earth's climate. Respond to the following based on your reading. Choose two feedback processes and describe how they're related to each other. Briefly explain how a Milankovitch cycle can start and end a prehistoric ice age.

Answer 1

1. Ice-albedo

2. greenhouse gases

3. negative

4. ice-albedo feedback and greenhouse gas feedback are related to each other. Warming due to ice-albedo feedback can place significant amounts of carbon dioxide in the atmosphere, which can then affect the rate of emission of other greenhouse gases.

5. Increased insulation or decrease in albedo from greenhouse gases causes surface temperatures to increase. This will then cause polar ice caps and glaciers to melt, decreasing albedo. As polar ice caps and glaciers melt, they emit their trapped greenhouse gases back into the atmosphere. This causes Earth to trap more heat, leading to further increases in surface temperatures and melting

Answer 2

Answer:

Explanation:

1. ice-albedo

2. greenhouse gases

3. colder

4. positive

5. negative

Explanation:

6. ice-albedo feedback and greenhouse gas feedback are related to eachother. warming due to the ice-albedo feedback can place significant

amounts of carbon dioxide in the atmosphere, which can then affect the rate of emission of greenhouse gases.

7. during a milankovitch cycle, isolation on earth changes due to earths orbit. this can cause global cooling to begin if the isolation decreases during a milankovitch cycle, or it can cause global warming to begin if isolation increases during a milankovitch .
