AC has never been as much of a climate challenge as it's portrayed to be. The demand profile lines up far better with peak solar availability (shited in time by batteries) than the winter load of electrifying heating, which will be much, much harder.
AC debates assume universal adoption is a climate villain. New PBL/IMAGE modeling: closing the global cooling gap entirely (3.6 billion people!) raises 2050 emissions by just 3.6%. Universal cooling’s climate footprint is… small.
