Answer:
A. Global warming is the cause
Explanation:
Our climate is getting warmer due to production of heat wave because the heat wave has high temperature which increases the temperature of the surrounding environment. Researchers found that as global temperatures increase, heat waves will become more frequent and the time between them will become shorter and we know that global temperature increase due to global warming so we can say that global warming is the cause of more heat wave.
