Spongy cities are the future

Los Angeles is an unlikely champion of a new wave of water savvy urban planning. A city most of us think of as all about cars and concrete has introduced more permeable surfaces to soak up water rather than turning it into run off. The change has been so successful that not only was severe flooding avoided during recent extreme rainfall but it will help solve the city’s water supply issues.

LA’s garbage fights back

Two of the largest landfill sites serving Los Angeles are suffering underground chemical reactions undermining their stability and releasing toxins and greenhouse gasses. How many more such dumps are pumping out methane, I wonder?

In a comic or a b-movie, the waste stew would have been hit by lightning and become some sort of shambling monster. But real life gives us the rotten egg stink of hydrogen sulphide and the long term horror of climate change.
