Erik, I think only a few scientists who have studied it thoroughly believe that it was only a local event. The below link shows where all of the different studies are that document the Medieval Warm Period. I think you can see it was worldwide. The Medieval Warm Period is a major threat to the climate alarmist scenarios so they have to try to prove it was local. See: http://www.co2science.org/data/timemap/mwpmap.html Whether the Antarctic Ice Sheet is growing or not appears to be a matter of controversy see: http://globalwarmingquestions.googlepages.com/ar4ant But I don't think it is problem for me either way. I don't dispute current global warming. I do believe that Hansen and Mann, strong climate alarmists, do want the Medieval Warm Period to disappear. I think we need a national debate with all parties given a chance to produce their evidence. There certainly is an internet debate but the mainstream media gives only one side air time. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of erikhansen@TheBlueZone.net Sent: Thursday, March 12, 2009 7:01 PM To: Utah Astronomy Subject: Re: [Utah-astronomy] "Hockey Stick Graph"

Don,

Well you are disagreeing with scientist out of your expertise, in regard to the middle ages. As for the antarctica ice growing... The link you provided was from 2002, the same year the Larsen B ice shelf collapsed, I think we can eliminate that from the discussion. This is the link you provided: Note the date (2002), it was refuted by that major event that year. I guess that escaped the author. I would bet he was embarrassed. http://www.co2science.org//articles/V5/N40/C3.php "In February-March 2002 the Larsen B ice shelf, a mass of floating ice some 220 meters thick and larger than Rhode Island, broke up into icebergs. The flow of glaciers held behind the ice shelf accelerated. The ice shelf had probably existed since the last ice age. This was only the largest in a 30-year series of retreats of ice shelves along the Antarctic Peninsula, the only part of the continent that scientists had predicted would be affected soon by greenhouse warming." Do you want to see the satellite image? Do you believe this event a hoax? Do you have something more recent? Every report I have heard or read from Antarctica is that indeed the ice is receding on the coastal regions of the continent. This is the only thing Global Warming predicts (soon), and that snow fall may increase in the interior of antarctica. The article I gave a link to says this that makes the glaciers less stable adjacent to the ice sheets. It seems what is happening in Antarctica maybe the most alarming because they know so little about the glaciers. They have discovered the glaciers seem capable a very rapid motion (previously not believed possible a few years ago), and may be very active where the rubber meets the road.

This graph, I believe, does not properly show the Medieval Warm period.

And

the black curve projection did not occur - everyone knows 1998 was warmer than the following years.

Current global warming is also more confined to the northern hemisphere since the Antarctic ice sheet is growing. See my previous links

I probably didn't make it clear. I saw an article about this in Scientific American (I can't remember which issue) and then I found the Wall Street Journal Science video on the web today. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of M Wilson Sent: Friday, March 13, 2009 3:34 PM To: Utah Astronomy Subject: Re: [Utah-astronomy] Invisibility It seems to me that the URL also would lead one to the Wall Street Journal and not Scientific American --- On Fri, 3/13/09, Chuck Hards <chuck.hards@gmail.com> wrote: From: Chuck Hards <chuck.hards@gmail.com> Subject: Re: [Utah-astronomy] Invisibility To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Friday, March 13, 2009, 1:00 PM Invisibility is real.

Does anyone know the topic/speaker for Tuesday night's SLAS meeting? I mean besides the awesome incredible fantastic stupendous DIY mirror making video? Thanks, Dave B.
