NPG Forum: In Support of a Revolution by Lindsey Grant November 1997
N2 molecules, into a form usable by plants and animals: falling meteors, ozonization and ionization by lightning. The only biotic process is the creation of ammonia by various bacteria, most ... are no substitute for a wiser demographic policy. Dr. Smail cites the possibility of reducing energy and resource wastage by half or two-thirds through such measures. An optimistic estimate. Moreover ...

energy efficient homes: greenhouse gas-"Is Global Warming caused by greenhouse gases or by the Sun?"
Recently an experiment called SKY (Cloud in Danish) was made by Svensmark which conclusively confirmed this cloud forming mechanism experimentally and that this type of cosmic ionization has an important seed effect on clouds. Links between low cloud cover variations and high energy particles intensity have also now ...
