    Anyone spewing as much hot air as Barry should be singled out.

    President Obama should be more active in the debate on mankinds altering of the climate we depend on for our agriculture. However, that is moot, because no matter what he says or does, the deniers have the upper hand at present. And will have until the problem becomes so acute that the denial cannot no longer be stated. However, by then, all we can do is deal with consequences. Consequences that we are seeing starting already.

    Sure olfraud sure. Your own groups claim that for the piddling expense of a trillion dollars we the human race can lower (possibly) the temperature by one degree more then 100 years in the future.....maybe.


    Sounds like a great investment. And please inform the class on exactly what is so bad about a three degree rise in global temps. Be detailed and no computer models. Please use paleoclimate records and paleobiologic records that describe what occured the last time the worlds temps were that high......which was long before man could influence the temps.

    He helped the White House press the House to pass a global warming bill in 2009 that would have set the first-ever limits on the pollution blamed for global warming, a bill that died in the Democratic-controlled Senate.

    Lame. It was the Blue dogs in the Senate not the President.

    The Eemian interglacial was the penultimate warm period enjoyed by the Earth during the Quaternary (the last one is the current epoch: the Holocene).





    According to the most used dating system (something we will discuss later on), 127,000 years ago the penultimate glaciation ended and an interglacial period lasting several millennia began. This period is known as the Eemian. The interglacial lasted until 118,000 years ago, although it hung on until 106,000 years ago in Europe.





    The name given to the penultimate interglacial era in Europe comes from the Eem river valley in Holland, where sediments from that epoch were found containing warm-weather fauna fossils and pollen from leafy trees. It is believed that at the height of that interglacial epoch, global temperatures were between 1º C and 2º C warmer than today. Models which take into account then-and-now differences in insolation levels and pollen analyses indicate that in parts of Asia, July temperatures were as much as 4º C warmer than today. However, in some exceptional cases, some models raise doubts as to whether the mean global temperature was actually quite that high (Winter, 2003).


    Chapter 6. The Eemian. 1. Heat 2. Higher sea level 3. Different insolation 4. Climate stability An important unanswered question: when and where did the interglacial begin? 1. Heat


    In England, where the period is known as the Ipswichian interglacial, many fossils of hippopotamuses and other animals only found today in tropical and subtropical regions have been found. In Greenland, ice cores indicate temperatures of 5º C higher than today, 123,000 years ago (North Greenland Ice Core Project members, 2004). In the Arctic, the expanse of winter ice shrunk and the temperature of the oceans’ surface waters was also higher than at present. Based on the study of alkenones and the Ca/Mg ratio of foraminifera, we can conclude that the surface waters of many seas were between 2º C and 3º C warmer than today (Lea, 2000; Pelejero, 2003; Martrat, 2004).

    .............................................................................................................

    At that time, the sea level was between 4 and 6 metres above its current mark. This may have been due to the fact that a large part of the ice sheet that today covers the western part of Antarctica did not yet exist. However, another, highly controversial, hypothesis states that the elevated sea level was due rather to an almost complete melting of the Greenland ice sheet (Cuffey, 2000). Nevertheless, during the exploration of the Dye-3 ice core site in southern Greenland, ice dating from that epoch was found, thus indicating that the Greenland ice sheet remained almost completely unaltered (Oerlemans, 2006).





    The high sea level recorded during most of the Eemian epoch gave rise to a number of changes in the world’s coastlines. It is possible that Scandinavia became an enormous island when part of Finland was flooded by the rising seas, an event which would have joined the Baltic Sea with the Arctic Ocean. It is also possible that the Jutland Peninsula in Denmark would have been cut off from mainland Europe.

    Of course, this rise occurred over a period of thousands of years, not the couple of hundred years in which we expect to see a similiar rise due to the GHGs we have emitted. One of the consequences of such a fast change is a very unsettled weather pattern as the atmospheric and ocean currents settle into a new pattern. Which, of course, puts our agriculture at risk. Look at the last year, Russia, Pakistan, China, Australia, Texas, and now our Mid-West.

    Phil Jones and the unaltered data agree: there is no Global Warming at the present time

    Also in "Earth in the Balance" Gore blames water vapor for the warming.

    That's water vapor.

    H2O

    CO2 lags the warming.

    Warming first, more CO2 follows
