REFLECTOR: New aviation fuel

Look up the word "Precession" in a good scientific/astronomy based book. It 

will tell you about the way the axis of the Earth moves around, dragging the


temperate zones with over a 46K year period. 

 

I'm sure this isn't the venue for this discussion; but, yes, there is a
46,000 year cycle.  There are a number of cycles that are shorter, and a few
known that are longer.  Knowing the behavior of these cycles from the past
gives a pretty good clue about projecting forward. Lots of good long-term
data has come from ice core studies over the last decade.  The curious thing
is, though, that starting about 100 years ago, there appears to be a
departure from the 'normal', and the rate of departure has increased in the
more recent decades.  Is it just coincidence that the departure begins about
the time humans began to burn fossil fuels?  And, of course, physics tells
us that CO2 does have an insulating effect.

 

A substantial portion of a huge amount of that carbon (much from CO2 ) that
was deposited in the earths crust over a period of many millions of years
has been returned to the atmosphere in a mere blink of an eye - about 100
years.  It is not surprising that it upsets things a bit.  It is the
departure from 'normal' cycles that makes up the study (science) of global
warming.

 

The media (and some scientists that are looking for funding) prefer to
overlook the distinction, and project calamitous results over a fairly short
term, including citing GW as the cause of Hurricane Katrina (hey, it sells).
There is no doubt that some of the warming over the past 50 years is due to
natural cycles; but it also seems quite clear at this point that some of it
is not.

 

Just another guys point of view.
