Anna Merikin's Journal: Three causes of Global Warming?

Social scientists seem to be mad to measure the amount of global warming and reporters seem mad to blame it (the warming) on human life and culture.

HL&C are only one of at least three contributors, as far as I can tell, and perhaps not the most important vector of GW.

Another is the general warming that has been taking place for the past fifty-thousand years or so: the one that melted the Ice Age glaciers and that, apparently, is now warming the polar ones, too. The retreat of the glaciers has been more-or-less steady for thousands of years, apparently.

A third is the weakening of the Earth's Magnetic Field, because this allows more cosmic and other radiation to reach the surface of our planet, thus heating it up. This, depending on which source you believe, has been going on for three hundred years, or only two hundred. If it is the older figure, then human activity can be ruled out as a primary cause of GW as no activity I can think of save producing and transporting electricity could possibly have a connection to the EMF itself.

The EMF is getting so unstable, compasses in the Ozone Hole between Antarctica and New Zealand point south!

Recently, major newspapers have carried reports that the North Pole has moved out of Canada and into the Bering Strait.

However, if the EMF has been weakening for only two hundred years, that coincides, more or less, with the invention of electrical generators and transmission lines (all of which produce magnetic flux as a byproduct or necessary constituent of current flow.)

Of course, science always likes a good fight.

Either way, we humans should stop beating ourselve up over this and get on with the job of adapting to it.
