Issue Some small California cities obtain government services from larger public entities under contracts. These cities are known as Lakewood plan cities or contract cities.

It’s the flickering that’s the culprit.

Image via Wikipedia Eustasy is associated with land movement (subsidence, plate movement, seismic activity), thermal expansion, and the movement of water stored on land to the sea. The GFDL climate model estimates that at 2 times the current CO2 levels, the sea level rise in 100 years due solely to thermal expansion would be approximately…
Image via Wikipedia Claude Lévi-Strauss died last week at 100. I first heard of him when I read Structural Anthropology in college. He identified myth as a type of speech through which a language could be discovered. His theory attempted to explain how myths are similar across cultures.
