Question

the epa presented information concerning atmospheric greenhouse gases. in 2014, they estimated that there were 6,870 million metric tons of co₂ in earth’s atmosphere. based on this information, how will previous antarctic temperature data, as seen in this model, change, if at all?
a the antarctic temperature should drop below 0°c.

b antarctic’s temperature will rise well above 0°c.

c the temperature in the antarctic will slowly rise over time.

d antarctic’s temperature will continue to fluctuate, above and below 0°c.

Explanation:

Greenhouse gases like CO₂ contribute to global warming. The Antarctic, being part of the global climate system, would likely see a slow temperature rise over time due to increased greenhouse gas levels (as CO₂ levels are high here, 6,870 Million Metric Tons). Option A suggests cooling (unlikely with greenhouse gases), B suggests a large rise above 0°C (not necessarily "well above" from this info), D suggests fluctuation (but the trend with greenhouse gases is a general rise, not random fluctuation). So C is the most consistent with the impact of greenhouse gases on climate - a slow rise over time.

Answer:

C. The temperature in the Antarctic will slowly rise over time.
