First, an inter...Loss of Summer Sea Ice -- Impacts<br /><br />First, an interesting look through the eyes of the native Inuits is provided in Dr. Heidi Cullen's recent book, "The Weather of the Future."<br /><br />If you do not have access to the book, there really is a huge list of impacts, and lots of research on all of them.<br /><br />Here on this blog, for example, there are tons of articles on melting permafrost. If you look at a map of northern Siberia, you can see that it was once an enormous flood plain or marsh running up to the edge of the Arctic Sea, which is not all that deep there.<br /><br />That land and sea will warm rapidly when there is no ice cover, releasing untold quantities of methane.<br /><br />Cullen points out that when there is ice cover, the air is much cold and drier. Further, the warmth in the water below the sea ice is not transferred to the air. We know that the water's temperature is increasing. Take away the ice cover and the energy gets transferred from the water to the air pretty quickly.<br /><br />The Inuit say that the ice does not form now like it used to because of clouds. It's one of those positive feedbacks.<br /><br />We can also expect the winds passing over this open water that reach Greenland to cause the Greenland Ice Sheet to melt faster because they will be warmer and wetter than if they had passed over sea ice.<br /><br />I am not exactly sure, but the changes in the monsoon over the U.S. Southwest may not be as affected by the lack of sea ice in the Arctic as it is by the huge amount of heat pumping out of the Pacific Ocean at the Equator.<br /><br />The thing that I think no one really knows is just what exactly the new weather pattern will be over the Arctic once the sea ice is gone and it is quite warm up there. Well, actually, I think the modellers have done the model runs but they just don't want to tell us yet. But let me put it this way (very simply) -- there used to be this cap of cold air that hung around the North Pole, and the hot air from the south has been pushing that cold air out of the Arctic, and just weakening it, and reducing it. Eventually, there won't be a lot of it left. What is that going to do to weather patterns in the Northern Hemisphere? I'd venture to say that they won't be anything like what we have been used to for hundreds of years.Tenney Naumerhttps://www.blogger.com/profile/11843130378338023902noreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-64016484732101724372010-09-19T16:30:08.660-05:002010-09-19T16:30:08.660-05:00Dear MP,

I was particularly stunned because I recognized the events in the animation because I had been going to the Weather Channel site to look at their IR animations of South America (since I live down here). Let me see if I can find that link because it is pretty cool.<br /><br />I have it on this blog somewhere.<br /><br />In the meantime, please have a look at the selection available from the Univ. of Wisc.<br /><br />Oh, and if I write something that is totally out to lunch, please feel free to correct me.<br /><br />http://cimss.ssec.wisc.edu/tropic/real-time/mosaic/images/images.htmlTenney Naumerhttps://www.blogger.com/profile/11843130378338023902noreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-46584404055813689392010-09-19T10:40:57.576-05:002010-09-19T10:40:57.576-05:00Hey, Tenney - have you seen any research that draw...Hey, Tenney - have you seen any research that draws the dot-to-dot picture of the impacts of loss of summer sea ice? I did a poll on my site, and half the folks said that they thought that we'd have an ice free arctic by 2030, but that it would have little impact (ie, costs of food and goods will go up some, but my family will be able to handle it) on their lives.<br /><br />I haven't seen anything about the effects of an ice free arctic on Lake Mead and Lake Powell, or about the economic effect of a mass migration of millions of eco-refugees from the US southwest. This seems pretty likely to me in the near (20-30 years) future, but I'm not seeing many folk outside of the scientific community taking it seriously.<br /><br />As far as politics, protocols, mitigation and "going green," it looks like we'll have an ice free summer arctic by 2030 no matter what is done; most likely we'll have an ice free arctic by 2020. <br /><br />But what does that mean? How is life going to be different? All I'm hearing is that storms are going to be "worse" and that we'll have more heat waves. The response I'm hearing from that is a collective shrug.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-67908440831873300712010-09-19T05:53:02.511-05:002010-09-19T05:53:02.511-05:00Tenney thanks for the links to the UWI water vapor...Tenney thanks for the links to the UWI water vapor imagery I had not used that before it will be great to show my class tomorrow.Anonymousnoreply@blogger.com
