Two things worry me about the earth's global warming:
1 We (the earth) orbit in an oval shape around the sun centered on one
of the one of the focal points. This gives one 'half year" about 7
more days than the other. Precession seems to get the blame for the
siderial year being about 20 minutes longer than the earth year. I
believe it is the Anomalistic Year that causes this. I cannot find an
informative source of knowledge to confirm this but it seemes to me
that the southern hemisphere continually gets more radiation from the
sun. This 20 minute difference causes the calender year to circle the
stars in about 70 years. Precession would only account for 3 seconds a
year and it ought to be accounted for in the 24 hours a day anyway. Do
scientists take this into account in their global warming
calculations?
2 Eversince the industrial revolution started we have been using fuel
of some kind to drive our machinery. Now we are told in one of our
first lessons in physics that one cannot destroy energy it is always
converted to another form. So a device, a car engine shall do, can be
said to be 75% efficient. That means that 25% of the energy has
already been discharged in to the atmosphere as heat. The car goes
along the road at 100 km/hr heats the air that it is forced through,
expends heat at various poinst like the breaks, tyres, and the
surface of the road.
When the fuel tank is empty every last Joule of energy in the in the
fuel has been left behind in the atmosphere as a temperature rise. In
other words for 250 years every bit of coal, oil, gas, and wood
including bush fires and depleation of the forrests - has left heat in
the atmosphere.
The scientists seem to be yelling about carbon dioxide heating the
globe. I would like to see some sums, do they include the above two
factors?
