ONCE again I refer to the topic, if only theoretical, of (let us all tremble in fear and heat) global warming. My objection to this is, and always has been, not that it is not happening. It is that there is no scientific way to know, or to measure, if it is happening. I shall give an example.
Icebergs, like the one which sunk the largest metaphor ever to sail the seas, are the result of glaciers. A glacier pushes ice down to the sea. Then, for various reasons, part of the ice falls off, and into the sea. This procedure is officially called “deficit spending.”
As ice, glaciers, and icebergs, are all things which should be directly related to global warming, then number, and/or size, of icebergs should be a way to measure such a trend. But consider the following. If the world is colder then more ice forms, and this forces the glacier to move more quickly to the sea, forcing more icebergs to fall off as more ice gets to that critical “jump” point.
However, consider the following. If things are warmer the ice is warmer and thus not as strong. Less of an ice mass in the glacier may cause it move faster, as there is less fiction. Its weakness allows the ice to break free easier. This is the way we used to defrost the old freezers. Heat applied near the ice causes it to fall apart.
So more and fewer icebergs mean that the Earth is both cooling and warming, at the same time. By the way, I do not believe that there is any way to determine if there are more icebergs than before. They do not willingly submit to a census. Nor do they travel in herds. I am simply pointing out that real science does not take the same set of data and arrive at two mutually contradictory conclusions, both being logical.
