If the Sun got hotter or cooler would we notice on Earth?

Question

We all know that an average temperature rise of even 5°C would have catastrophic effects on our planet. Then wouldn’t the Sun changing temperature by 5°C have a similar effect?

Answer 1

The outer shell of the sun is about 5 million degrees C. Dropping that by 5C won’t do much to the amount of energy it emits, so we most likely wouldn’t notice or be impacted.
