In Moscow, the enterprise of scraping the snow off the streets and pavements, forming it into snow hillocks, carting it off in 6, 000-odd snow vehicles for dumping or melting, and finally zapping it with chemicals to speed the thaw is vast and costly (which helps to explain why Yuri Luzhkov, the city's mayor, threatened last year to fine meteorologists who make wrong forecasts).
