In the last few months, the consequences of climate change have hit different parts of the world with a mad vengeance. Here in Finland, that took the form of the warmest December on record leading many people to bemoan the lack of snow. As an Englishman who’s experienced many a Finnish winter, I instead wallowed in the balmy temperatures confident in the knowledge that we had three more months of sub-zero, beard-freezing hardship to come. That was demonstrated, in fine Arctic style, this week when temperatures plummeted as low as minus 28 in Helsinki. One surreal consequence of this uncannily fast freeze was an awe-inspiring phenomenon which makes the sea look as though it’s cloaked in smoke. Both beautiful and bizarre, it literally took my breath away.
