Which is a primary argument of the opponents of the global warming theory?

A. Solar winds blow heated air from the upper atmosphere.
B. Earth’s rising temperatures are part of a recurring cycle.
C. Global warming advocates have no background in science.
D. Anyone can see that the oceans are not rising as predicted.
is it C?

It is B

No, the primary argument of the opponents of the global warming theory is B. Earth's rising temperatures are part of a recurring cycle. This argument suggests that the current increase in global temperatures is a natural occurrence and not primarily caused by human activities.

The primary argument of opponents of the global warming theory can vary, but out of the given options, the most relevant one is B. Earth’s rising temperatures are part of a recurring cycle.

To arrive at this answer, we can analyze each option:

A. Solar winds blow heated air from the upper atmosphere: This argument is not widely supported because the primary driver of global warming is the greenhouse effect caused by the accumulation of greenhouse gases, not just heated air blowing in from the upper atmosphere.

B. Earth’s rising temperatures are part of a recurring cycle: This argument suggests that global warming is a natural phenomenon that has occurred in the past and will happen again in the future. Some opponents of the global warming theory argue that the current warming trend is within the range of natural climate variability rather than being solely caused by human activities.

C. Global warming advocates have no background in science: This argument focuses on the credibility of the scientists supporting global warming theories, rather than the scientific evidence itself. While some opponents of the theory may claim this, it is a generalization and not a direct argument against the theory itself.

D. Anyone can see that the oceans are not rising as predicted: This argument questions the accuracy of predictions regarding rising sea levels due to global warming. However, it does not provide a direct argument against the theory itself.

Therefore, option B, which suggests that Earth’s rising temperatures are part of a recurring cycle, is the primary argument of opponents of the global warming theory.

I hear B most frequently.

It would be hard to say that people who warn of global warming have no background in science. By the way "advocates" is the wrong word.
