As a desert, the Sahara poses not a few problems for the unwary. It's
temperature changing as it does so rapidly makes exposure the chief
cause of concern. However it was not a danger to this diurnal
behaviour to which my first post to this thread was in reference.

For years the UN and subordinate hangers on, were telling us the
Sahara is expanding and could we please give them lots of money to use
wisely on the behalf of the poor indigents.

Later when they began talking about global cooling they released data
that showed this Saharan threat was not the case at all.

The link does mention that the desert is encroaching on certain parts
of Africa, one might care to remember that the countries mentioned are
at war and have been for decades, little wonder that any natural
defences to the desert are down. (Little wonder they are at war given
their peace is in the hands of the UN.)

What I was actually looking for was a statement that the
desertification of the Sahel was a cyclical thing and that global
warmers have recanted on their earlier stance.

I do believe the earth is in a bad shape. However it is not due to
temerature rises in the sun as such. I'm not saying it is not due to
pollution either. In fact the form of pollution affecting the planet
is deeper than any simplistic "stop burning things" point of view.

So now we have proof that Greenland is not a simple ice-cube in the
fridge equation. However there is one equation that is yet to change:

It takes a lot of heat to melt a lot of ice.

It takes a lot of a lot of heat to boil it.

Once in the atmosphere it acts as a valve stopping heat entry.

Heat is evolved as the temperature drops and the ice returns.

The quickest way for the heat to dissipate is out into the wide,
nebulous yonder. To be lost for ever -unless in its peregrinations the
vestiges of our stars light is returned in kind.
