- p085 James Walker and Jim Kasting suggest escape from an ice catastrophe because of a pressure broadening of CO2 absorption spectrum, "but not included in global climate models, simply because no one ever suspected that this has actually happened.
- fooey. This is part of current climate models, part of the CO2 contribution to warming
p233 Triassic Rebound, 250 to 245 MYA ... Sulfur bacteria "... environmentally challenging world for animal life, trough in oxygen, new respiratory systems, emergence of mammals and dinosaurs
- p354 hopeful future, or ..." carbon dioxide causes all ice on Earth to melt, raising sea levels, slowing the thermohaline circulation patterns, bringing stagnation followed by anoxia to the ocean bottoms, then to ever-shallower waters, at the same time liberating toxic levels of hydrogen sulfide to percolate out of every single ocean"
- no cite or quantification. (1) is that much sulfur actually available, and (2) how fast?, and (3) what technofixes are available. I agree that it is best to avoid this, but mostly believe that carbon is for construction, not combustion. How can we create high strength carbon fiber with all the excess carbon?
