Drs. Gordon, Bhaskar and list: 1. This is first to follow up on Dr. Bhaskar's request to Dr. Gordon, hoping that he will answer his yesterday-question below asking you to explain the : " variety of possibilities to explain the warming ..." [I have highlighted it and 3 others below] I believe that you are on a list where any non-CO2 response will be quite clinically rebutted. I urge you to check out those "possibilities" at www.skepticalscience.com before giving them here. I hope you can then join the "believer" (CO2-causation) group in as the only one that I find can't be readily rebutted (as done at the several sites given below)..
2. But mostly I am asking a new question - to give a citation for your earlier sentence below : " The global increase has been about 5 degrees C for the last 10,000 years or about 0.0005 per year and 0.05 degrees for the past 100 yea rs I follow a lot of denier literature and have never seen this one - I doubt it can even be found at "skeptical science". Yes, one can find a lower temperature roughly10,000 years ago and probably of even greater than 5 degrees C. But at a slightly later time, it was higher than today and has been mostly declining until the last century or so. The same decline (but faster slope) is seen in all of the 100,000 year Milankovitcch cycles. To take recent high temperatures and a lower value 10,000 years ago to find an average positive slope is an approximation beyond mathematical credibility. For my side of the story, I ask you to read : a. http://www.skepticalscience.com/heading-into-new-little-ice-age.htm (has considerable data showing declining temperatures due to Milankovitch cycles b. A figure at comment #217 will be recognized as the "Hockey stick" at http://www.skepticalscience.com/argument.php?p=5&t=258&&a=53 All declining temperatures until recently - and these not as rapidly declining as in ALL earlier cycles. c. Excellent set of response comments by Bill Ruddiman to his also excellent original short "paper" at http://www.realclimate.org/index.php/archives/2011/04/an-emerging-view-on-early-land-use/ I saw only a few denier comments there. d. My Geoengineering (CDR; biochar) reason for being interested in this topic is explicated by Erich Knight at comments #69, 90, 95 at http://www.realclimate.org/index.php/archives/2011/04/an-emerging-view-on-early-land-use/comment-page-2/#comments Again, I ask for a citation for your view of this same time period. 3. If you find you have erred on the above two points, I'd be interested in knowing if you still stand by your two terms following the two repeated above: "...it is sheer stupidity in the extreme. " and " CO2 freaks " 4. I have also highlighted below a few of your Friday-remarks - and wonder if you care to take any of those back as well?

Gene You said " ... There are a variety of possibilities to explain the warming ..." What are they? The increase, over the past 200 years, in burning of fossil fuel, CO2 level of atmosphere and oceans and rise in temperature are very well documented and the correlation is very high. You seem to be arguing against yourself. As per your own statement natural warming is only 0.0005 per year i.e., 0.05 degrees over 100 years. The actual increase in the past 100 years is about 0.8 degrees C, this is much more than the 0.05 degrees you mentioned. regards Bhaskar On Saturday, 22 September 2012 19:59:57 UTC+5:30, Gene wrote: Bhaskar: You are totally correct; I could not agree more. However, potential solutions depend on the cause. The global increase has been about 5 degrees C for the last 10,000 years or about 0.0005 per year and 0.05 degrees for the past 100 years. [RWL: Emphasis added here and below .] That gradual rise is not the current or nearterm cause or issue. There are warming and cooling cycles, several per 1000 years and we may be in a warming cycle that accounts for the current warming. We are also in a Malenkovich cycle. There are a variety of possibilities to explain the warming and CO2 may be only a minor player. The point is that it is warming and the strategy for controlling the warming needs to be worked out and proven so it can be implemented as necessary. To conclude it is CO2 and ALL we need to do is reduce CO2 concentration is not warranted; it is sheer stupidity in the extreme. We need a thermostat that works and only geoengineering can provide that. I am appalled that the CO2 freaks have been able to block the emergence of a serious geoengineering effort. -gene From: "M V Bhaskar" < bhaska...@gmail.com > To: geoengi...@googlegroups.com Cc: eugg...@comcast.net , rev...@gmail.com , "Ken Caldeira" < kcal...@carnegiescience.edu >, "Geoengineering" < geoengi...@googlegroups.com > Sent: Saturday, September 22, 2012 8:05:50 AM Subject: Re: [geo] Geo-engineering and Arctic mentioned here. Eugene What difference does the cause of the problem make to solving the problem? If Global warming and ocean acidification are problems, we should find ways to solve or mitigate them. No one is trying to punish anyone for causing the problems. We are only trying to solve it. I am sure that you will agree that even if global warming is, mainly or partly, due to natural factors, anthropogenic activity is adding fuel to the fire. :) regards Bhaskar On Saturday, 22 September 2012 08:59:16 UTC+5:30, Greg Rau wrote: <blockquote> Eugene, What then is your opinion on anthropogenic CO2 induced ocean acidification?

Fascinating input. Scary. Good input but spoiled gratuitously. I take exception to the gratuitous comment in the second paragraph of 'human driven' cause ignoring the fact that it not scientifically proven that global warming is human driven and because it has been warming on average for 10,000 years without enough humans or CO2 around to make a difference; AND there are cycles of warming and cooling overlaying the general warming trend. One can have an opinion, FINE, but opinion does not substitute for proven science and the theory of CO2-driven global warming clearly remains to be proven using the accepted scientific process. Science is not an election and AGW remains to be proven. until it is proven it remains a not so robust hypothesis. Why is that so hard to understand? Is it debatable? </blockquote> -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
