FYI: Weather in Middle Earth

From Australia Broadcasting

Lunt took Tolkien's detailed maps of Middle Earth showing continents and mountains, and essentially "scanned" them into the supercomputer, the Guardian reported. Then he ran the numbers to get a 70-year model.
In a mock research paper published under the name Radagast the Brown, Lunt details climate details and weather predictions for Tolkien's fictional world. He compared the climate surrounding Mount Doom in the heart of Mordor to that of Los Angeles and western Texas. He argues that those areas have dry, hot climates with little vegetation and therefore match the conditions in fictional Mordor.
