The Cuyahoga River in Cleveland, Ohio, caught fire, in 1969. Randy Newman wrote a song about that. This week, in London, UK, things in a neighborhood in London are burning, the heat being supplied by a new, tall building that—for lengthy periods of the day during at least part of the year— focuses sunlight down at that neighborhood. Io9 has a nice description of this new phenomenon, and points to the news video you see here, below the Randy Newman video. Below that, a second news report about the London excitement. Burn on, big river. Burn on, big building.
