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.

The tropical Atlantic ozone sink

Measurements in the Atlantic have shown that the actions of ultraviolet light and sea spray are scrubbing ozone and methane out of the atmosphere in the area faster than expected. Which is fairly good news, if only we can stop pumping out so many pollutants the Earth may clean the rest up faster than we deserve.
