When it fills the low place surely the high place is screwed? Is there not enough air to go around or what? Same with temperature. It's high pressure in Ireland today. Why? How? What's putting the pressure on the air? If there's more pressure on the air to cause it to heat up, is there more pressure on me ? Heating me up ?

The lighter air floats away leaving a vacuum which sucks in air from elsewhere. As you well know there is a hole in the Ozone Layer so no, there isn't enough air to go around and as if that wasn't bad enough we are digging pits and mines so there is a lot of air underground that used to be overground.
