I’m in the Netherlands (around 52ºN) and in my opinion DST is counter productive, especially considering the effects of global warming.
Summers are getting hot, to the point where it’s uncomfortable to be outside while the sun is out. It’s barely tolerable in the shade, assuming you don’t move too much. It only gets comfortable outdoors after sunset. During workweeks this means you barely have any usable outdoor time before you need to go to sleep. It also means your bedroom has little chance to cool down before you need to go to bed. Summer nights are nice when you’re outdoors, but DST robs us of the best hours to be outside.
If we’re going to move the clock in summer, we should move it backwards another hour. It would mean 2 more hours (compared to the current DST) of nice summer nights, instead of extra hours of scorching sunlight. I suggest we call it ‘Moonlight Saving Time’.
