Question

If it were possible to stop increases global temperature without reducing atmospheric CO2, which of the following would be true.

A) Species would still have to migrate long distances to stay within their climate envelopes.

B) It would reduce ocean acidification.

C) Result in a slowing of the methane-permafrost feedback.

D) Emissions would slow.

Answer 1

Answer:

If it were possible to stop increases global temperature without reducing atmospheric CO2, which of the following would be true.

1. A) Species would still have to migrate long distances to stay within their climate envelopes.
2. B) It would reduce ocean acidification.
3. C) Result in a slowing of the methane-permafrost feedback - Correct Option (Explanation: Permafrost refers to the permanent frozen layer present below the Earth's surface in cold Arctic regions. When earth warms, then some carbon present in this layer is released to the atmosphere as methane or CO2.. Increase in Temperature causes Permafrost to thaw thereby causing an increase in methane emissions causing a positive feedback loop. However, if the increase in global temperature is stopped without reducing atmospheric CO2, it will result in a slowing of the methane-permafrost feedback.
4. D) Emissions would slow. .
