Kit Stolz blogs:..."We Are Now On the Hairy Edge..."<BR/> <BR/>Kit Stolz blogs:<BR/><BR/>For a modest man, Dr. James Hansen, the Cassandra of global warming, has become quiet fiery.<BR/><BR/>To wit (from his most recent letter to Angela Merkel, prime minister of Germany, on why she must not allow coal plant construction):<BR/><BR/>...we must have a prompt moratorium on the construction of coal-fired power plants that do not capture CO2, and we must phase-out existing coal-fired power plants over the next two decades. It is foolish to build new plants with the knowledge that they will have to be bull-dozed in the near future.<BR/><BR/>Given the fossil fuel facts summarized in the letter, the alternative to elimination of CO2 emissions from coal use would be to place a contraption on the back of each of our automobiles to capture the CO2. Remember that the mass of the CO2 is more than three times larger than the mass of the fuel in the tank. Can you imagine the price of this contraption? And where are you going to take and stow the CO2 after you capture it?<BR/><BR/>One of my next posts will be a paper that I hope makes the story clearer. We are now on the hairy edge. We are, in fact, going somewhat beyond the safe level of atmospheric CO2, but there is enough potential for storage of CO2 in soils and the biosphere that we can take care of the excess via improved agricultural and forestry practices, improvements that make sense for other reasons – provided that we phase out coal use except where CO2 is captured and sequestered.<BR/><BR/>Old geezers living on high ground may not be concerned about ice sheet stability and future sea level rise, or the out-of-control mess that we threaten to leave for coming generations. However, when one looks at species loss and its relation to climate change, simple calculation shows that each new coal-fired power plant will be a dagger in the heart of at least several irreplaceable species, even though we cannot identify specific species with a specific power plant.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-949421001644904537.post-51842677801860998872008-01-29T17:22:00.000-08:002008-01-29T17:22:00.000-08:00A top scientist in Alaska wrote to me:"Dear Danny,...A top scientist in Alaska wrote to me:<BR/><BR/>"Dear Danny,<BR/><BR/>My operative assumption is that enough uncertainties remain regarding<BR/>timing and rate of warming, possible implementation of greenhouse emission<BR/>controls, and specific effects of warming in particular regions, as to<BR/>make the plan to move cities beyond the list subjects that I believe I<BR/>could usefully contribute to.<BR/><BR/>Thank you, though, for showing me these images.

While the points presented may be valid in the event of the sudden disappearance of humans from the planet, a more interesting approach would have been to examine the effects of a more gradual decline in the human population which is a very real possibility, given the fact that we are already in the process of destroying our environment. As this process accelerates, world catastrophes will become more numerous and competition for shrinking available resources will intensify. If we survive as a species at all, I believe we will sink into another period similar to the "Dark Ages". And it could be that polar cities will be places where we must reside until the Dark Ages are over...."Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-949421001644904537.post-81516205099025323472008-01-26T19:26:00.000-08:002008-01-26T19:26:00.000-08:00After the End We Will Live Like Gerbils16 Jan 2008...After the End We Will Live Like Gerbils16 Jan 2008 by the Stormin Mormon <BR/>For more information on "polar cities", readers are sent to http://climatechange3000.blogspot.com/.
