Can I replace "implication" here with "effect"?
"Effect" and "implication" are similar, but slightly different in meaning. In this video, "implications" refers to the expected or likely consequence of the heat wave, so it is more similar in meaning to words like "consequences," "ramifications," "results," or "repercussions." It is usually used to indicate a negative outcome. Ex: The implications of the financial scandal will be huge. Ex: The upcoming elections will have profound implications for many people.
