Thank you for your kind advice; I'll take it, as I consider the free exchange of ideas to be the value of these discussion forums.  In the meantime, let me share a few comments with you.


As mentioned above, the ice has been melting for a long time.  There are natural changes in the earth’s climate that are cyclical, which occur over many thousands of years; however it is the acceleration of the change during the past few centuries that is alarming. There is only a thin layer of ozone that shields the earth from the sun’s rays that is being depleted by hydrocarbon emissions into the atmosphere; and it is indisputable that man is a significant contributor to this pollution.


What is needed is to restore the natural balance; we need to stop spewing man-made chemical emissions into the atmosphere in order to allow nature to heal itself. When you are dealing with the balance of natural forces, it only takes a little change to have big consequences. For example: a little mentioned aspect of global warming is the dramatic decrease in Antarctic krill; which is significant both for its role in regulating carbon emissions into the atmosphere and because it is at the base of the ocean food chain - not to mention a substantial commercial harvest. Krill feed on phytoplankton beneath the sea ice, and it is the melting sea ice due to rising temperature that has caused the decrease in krill populations. This decrease, in turn, will dramatically increase of amount of carbon emissions, exacerbating global warming and its effects.
