[Rhodes22-list] More on GPS

[TN Rhodey]

John, Interesting read...How long was the system "down". The article didn't 
seem to mention if it was just a few minutes or hours. I was just 
wondering???

Brad, Every now and then we agree! The Sun!....You know some say it is due 
to variations in the wobble of the spinning earth. These same wobbles are 
also thought by many to have caused various heating and cooling cycles over 
the earth's history. Maybe increase in population in India and China are the 
cause?

Slight variations in angle can make a difference. We all remember lightning 
fires with magnifying glass when we were kids right?....Get the angle just 
right and the glass would burn your brothers arm or small insect very 
quickly. Change the angle and nothing. That glass didn't work to well on 
cloudy days though....so maybe air pollution would reduce global warming 
because it can create a nice shade? :-)

I heard the problem is caused by trrapped gases creating greenhouse effect. 
So maybe if we had a bigger hole in the ozone these bad gasses would not be 
trapped anymore...just kidding about all this. :-) Heck I don't know who to 
believe. We do need to find some clean energy and quit fouling our nest. If 
our land, air and water are clean we and our food chain will be ok.
