As I see it, the main issues to be resolved in the Global Warming debate are: 1. What is the true historical temperature record? With numerous scientific papers and historical information supporting the Medieval Warm Period, the Roman Warm Period and the Little Ice Age why do the Mann and IPCC data deny their existence? 2. What is the real contribution to global warming of green house gases? The Brookhaven National Laboratory just released a report that was heavily debated in the Senate. See http://www.ecd.bnl.gov/steve/pubs/HeatCapacity.pdf This report states, The estimated increase in GMST by well mixed greenhouse gases from preindustrial times to the present, 0.7 ± 0.3 K; the upper end of this range approaches the threshold for 'dangerous anthropogenic interference with the climate system,' which is considered to be in the range 1 to 2 K. Of course the lower range .4 K makes green house gases a marginal problem. They basically split the baby in two with both sides claiming victory from the report. I am not sure this report properly accounted for solar variability. 3. What is the contribution to global warming by other natural means such as solar variability? Are we entering into a quiet sun era? Will any greenhouse gas effects be swapped by a solar minimum? I believe the long term solution is nuclear energy and the most logical scenario is to reprocess the spent fuel rods in place reducing the ultimate disposal problem to a minor problem of storing low level radioactive waste on site. Alternatively, we can do as T. Boone Pickens suggests and literally cover the Midwest with windmills using natural gas to cover power needs when the wind is not blowing. The nuclear energy scenario emits no green house gases. Ultimately maybe the problem of commercial fusion reactors will be eventually solved. Conventional oil production is estimated to peak somewhere around 2030 but oil shale production could support us another 100 years. As an aside, conventional oil production was first assumed to peak in the mid 1970's but major discoveries in the North Sea, the Mideast and Latin America changed that belief. Strip mining oil shale is not environmentally friendly but new in-situ techniques hold promise.
