Yellow to Red Acer
I bought an Acer plant a few years ago. Each autumn its leaves have turned yellowish. This year it turned a deep red.
I learned according to Forestry England it's because the hotter summer resulted in more sugar production, which resulted in deeper pigmentation.

As I am not a leaf I cannot confirm this with full certainty but I'll go with what they are saying.
Although, I cannot agree with the cheerful tone with which the soaring temperatures are being described. Replacing "thanks to" with "due to" and "warm" with "hot" would go a long way.
