Question

the graph shows ice core data that illustrate historical trends in the amount of carbon dioxide in earths atmosphere. scientists attribute global warming to recent increases in human activities that produce carbon dioxide. which trend would indicate that a new solution to the problem of global warming is working? atmospheric carbon dioxide from law dome ice cores year (ad) a. atmospheric co₂ levels would be increasing at a slower rate. b. current average temperatures would be increasing at a faster rate. c. ice core samples would be melting at a slower rate. d. greenhouse gases would be disappearing at a slower rate.

Explanation:

Global warming is linked to rising CO₂ levels from human - activities. A working solution would slow the increase of CO₂. Option A indicates a slower rate of increase in atmospheric CO₂ levels, which is a sign of a potential solution working. Option B shows a faster increase in temperature, which is the opposite of what a solution should do. Option C about ice - core melting rate is more of an effect rather than a direct indicator of a solution working on CO₂ levels. Option D about greenhouse gases disappearing at a slower rate is not a sign of a solution working as it implies less reduction of greenhouse gases.

Answer:

A. Atmospheric CO₂ levels would be increasing at a slower rate.
