WELL, IT IS HARD TO DISTINGUISH FROM WICCA:

Climate change belief given same legal status as religion (Stephen Adams and Louise Gray, 03 Nov 2009, Daily Telegraph)

An executive has won the right to sue his employer on the basis that he was unfairly dismissed for his green views after a judge ruled that environmentalism had the same weight in law as religious and philosophical beliefs.

In a landmark ruling, Mr Justice Michael Burton said that "a belief in man-made climate change ... is capable, if genuinely held, of being a philosophical belief for the purpose of the 2003 Religion and Belief Regulations". [...]

John Bowers QC, representing Grainger, had argued that adherence to climate change theory was "a scientific view rather than a philosophical one", because "philosophy deals with matters that are not capable of scientific proof."
