More common sense observations from here http://antigreen.blogspot.com/
Sea level has risen about 400 feet since the end of the last Ice Age, just 20,000 or so years ago. We are in an Inter-Glacial Period of natural warming which has caused the melting of the continental glaciers which covered much of the land mass in the Northern Hemisphere and was in some places 2 or more miles thick. Nearly all of this melted and most of the water entered the oceans. In general, this is all undisputed by scientists. It can be proven, and it has been.
Yet somehow the global warming alarmists like those now gathered in Copenhagen, want the world to believe we are all in peril from trivial rising sea levels and warming. They spread fear and exploit people's ignorance. It is despicable, and should be criminal.
"The Greenie message is entirely emotional and devoid of all logic. They say that polar ice will melt and cause a big sea-level rise. Yet 91% of the world's glacial ice is in Antarctica, where the average temperature is around minus 40 degrees Celsius. The melting point of ice is zero degrees. So for the ice to melt on any scale the Antarctic temperature would need to rise by around 40 degrees, which NOBODY is predicting. The median Greenie prediction is about 4 degrees.
So where is the huge sea level rise going to come from? Mars? And the North polar area is mostly sea ice and melting sea ice does not raise the sea level at all. Yet Warmists constantly hail any sign of Arctic melting. That the melting of floating ice does not raise the water level is known as Archimedes' principle. Archimedes demonstrated it around 2,500 years ago. That Warmists have not yet caught up with that must be just about the most inspissated ignorance imaginable.
The whole Warmist scare defies the most basic physics. Sadly, what the Vulgate says in John 1:5 is still only very partially true: "Lux in tenebris lucet". There is still much darkness in the minds of men. "
