Which is garbage reasoning because this is true in the states also, and yet, the last two weeks of school where I am we were in a heat wave, and four of those days they called for early dissmisal/half day due to heat, and sent the kids home at noon. Many schools dont have cooling outside of the offices (another issue), but you cannot learn (nor teach) when its too hot.

The children have been marinating in repeated Covid infections now for 5 years after restrictions were lifted and one of the consequences of Long Covid is heat intolerance. Now we are subjecting them to constant excessive and potentially lethal heat in classrooms that often don't even have opening windows let alone Air Conditioning. They really don't care if the children survive at all, just that the parents are forced to work so the billionaires can get a bit richer and own ever more of everything.

We can start by retrofitting passive cooling: external window shades are cheap and would make a big difference due to how big classroom windows tend to be.

Aircon is an air to air heatpump. Normally they can run in either direction.
