Mi smentisco subito, ma questa non potevo non segnalarvela. Adesso l'Economist ci dice che l'inquinamento serve ad abbassare la temperatura e a combattere il global warming. Un bel casino, eh?

If the Arctic is warming faster than might be expected, other parts of the world are warming slower. One reason for this, widely accepted by scientists but little appreciated by policymakers, is the sulphur given off by coal-fired power stations and some other industrial fossil-fuel use. Sulphur is very good at forming reflecting aerosols that can also make natural clouds both whiter and possibly longer-lasting, which provides an added cooling effect.
