Institute, west virginia: potentially similar event in bayer cropscience mic plant in 2008, killed 2, injured 8, residue vessel over pressurized, exploded and went through the wall. Includes 71 lbs of dioxin (lethal: what do we do to control pollution, historical approaches have relied on output control (collection) and dilution. The solution to pollution is dilution : eg. 1850; historic post-glacial warming was about 4-7 c over 5000 years: prediction are 2-6 by 2100. Evidence for anthropogenic role in global warming: carbon isotopes, c12 and c13. Plants have preference for c12, and have lower c13/c12 ratios, about 2% lower than the atmosphere. A similar trend is seen in ocean surface water over the past few decades similar evidence from marine sponges. Exactly what we would predict from fossil fuel burning. Positive feedback warming ice, melting, increased absorption by water and methane release, increased warming enhancement of the effect.
