Reference: Green rice next on researchers' agenda, Bangkok Post, April 21, 2009
The reference to methane as a 'greenhouse gas' (Green rice next on researchers' agenda, Bangkok Post, April 21, 2009) is erroneous. A greenhouse is an enclosed structure made of transparent material in which vegetables or flowers are grown during winter at lattitudes at which this would not be possible under ambient conditions. Carbon dioxide is called a greenhouse gas because greenhouse operators pump this gas into their greenhouse as photosynthesis nutrient for their plants as well as to maintain optimal CO2 levels in the greenhouse of around 1500 ppm. No greenhouse operator on earth ever willingly injects methane into their greenhhouse and this gas serves no greenhouse function. Therefore, methane is not a greenhouse gas.
