mLine 58:
Line 58: − − A group of scientists working at Harvard University experimented with a thermodynamic formula that expressed the potential change of the chemical makeup of the atmosphere mathematically. The entropy created by the heat released in burning fuels would increase the rate at which [[carbon dioxide]] and other "greenhouse gases" would be changed into [[water]] by multi-cellular organisms, demonstrating that increased industrial production of these life-generating gases will help perpetuate the ecosystems of the Earth.

Some scientists have noted a [[Global warming#Natural Climate Change on Other Planets|natural climate change on other planets]]; others have pointed to [[Venus]] as an example of a planet where a runaway greenhouse effect has already occurred. However, Venus has many differences with Earth, including a lack of plate tectonics which make the comparison faulty.
