Wintersmog, maand voor maand over de hele wereld

Kolenrook en een inversie in het dal; niet de kou maar de lucht is het probleem.

Dit is een waarschuwingspagina, geen aanbeveling. Wintersmog betreft 38 bestemmingen op SeasonMap; de maanden hieronder zijn die waarin het risicovenster open staat — de meeste weken daarin verlopen rustig, en de score naast elke plek is nog steeds de gewone klimaatscore, risico en al.
