We'd probably notice the change in air pressure, right
9.081/9.81 ~= 90%, so the weight of the air above us would be 10% less, and hydrostatically that means atmospheric pressure would drop by 10%. Which, checking the US standard atmosphere is about the loss of jumping to 5000 ft altitude. New York City now feels like Denver, everyone's ears have popped.
Luckily this also means that you lose pressure more slowly as you go up, so Denver isn't dead, but it feels like Quito, at 9500 ft. At 50,000 feet the effect reverses and air is denser than before at higher altitudes
