My OperaArctic Sea Ice – for how long still?
Friday, September 30, 2005 6:20:06 PM
Over the years I have seen hundreds of glaciers in Austria, Switzerland, Norway, Iceland, Greenland, Canada, Alaska, Chile, Argentina. Marvellous sights.
In most places I have seen evidence and/or been told by guides or local people that they are retreating. Because of global warming? Who am I to tell.
The arctic sea ice cover also seems to melt at a dramatic pace a.o. according to BBC News – Arctic ice ‘disappearing quickly’. The trend for the time being is 8% decline per decade or nearly 1% per year. This is not only bad news for countries that could be badly affected by sea level rise, but it may also lead to faster global warming through positive feedback effects. We are however talking about cover, and thus only the ice surface. The situation may be different for volume, and so far the ice thickness has not been thoroughly measured
On 8 October ESA will launch the satellite CryoSat on an ice mission to study this problem in more detail. “By measuring ice thickness on both land and sea very precisely over a three-year period, CryoSat aims to provide conclusive proof whether there is indeed a trend towards diminishing polar ice cover”.

I have seen studies done by the Discovery Channel and these show how global warming is happening however they never pose what we as Humans can do to slow it down.
It's always this way they show what happens but never bring the light to the surface to show how to stop things before they get to this point..
The point of no return.
Thank you for your information.
