Greenhouse gasses

[C M Smith <cmsmith@domain.elided>]

The major one is water vapour. Hydrogen fueled vehicles produce mostly 
this. Hydrocarbon fueled vehicles produce some of this. Carbon Dioxide is 
another less impressive greenhouse gas, hydrogen powered vehicles produce 
none of this, hydrocarbon fueled vehicles produce quite alot. Methane is 
pretty aggressive as greenhouse gasses go, cows produce alot of this, so do 
certain elements of humanity after a fatty meal.

There are NO vehicles which produce no greenhouse gasses, except those 
powered by solar power or exclusively nuclear electric (i.e. battery 
powered vehicles recharged exclusively by nuclear generated electricity). 
Reduction of greenhouse gasses is only possible if fuel consumption is 
reduced, or solar power or nuclear power is used exclusively, we stop 
eating fatty foods and reduce the number of cattle we grow.

Thought for the day: we are still in the Pleistocene age which is when the 
ice age happened. (There were lots of ice ages but the one people mean by 
"ice age" is the last one.) The last ice age ended??? about 10,000 years 
ago. The earth is still warming up after the ice receded. The ice age is 
not over it is just warmer than it was, but it is still a lot cooler than 
the Earth has usually been.

No one alive today is smart enough or knows enough to attribute current 
observed warming trends to anything we are doing, or not doing. Chances are 
excellent that we are having no material effect upon a warming trend well 
within normal cycles for this planet.

If you are concerned, drive less, or use a more fuel efficient vehicle. For 
my part, I intend to do my best to delay the onset of the next ice age.
