The questions are irrelevant.
On what do you base your 100% figure?
Missed your first post. Sorry
I disagree.
You said, " Global warming, the physical reality might be as much as 25% manmade."
So I challenged you and said :
1. What percentage of total greenhouse gases are natural?
2. What amount,in percentage, of total greenhouse gases are caused by water vapor?
3. What total percentage of greenhouse gases are man made?
More importantly,what percentage of CO2 is man-made ? What percentge of CH4 and N2O are man made?
4. If Kyoto were adhered to, what total reduction of temperature would result ?
