We can't change this infrastructure immediately, it was built for English summers which used to mean 30 in the air, 50-60 ground temp. Now we're pushing 40 air and 80 ground...
Aside - us oldsters from the 1900s need to stop referring to ~1900 as "The turn of the century". We're at a point where ~2000 will start (maybe is) being referred to as "The turn of the century" due to it turning in to the current century at that time.
