Your words exactly: If humans stopped or vastly reduced all greenhouse gas (GHG) emmisions immediately- what if the percentage of manmade GHGs turned out to be 2%? On the other hand, what if it turned out to be 20%, or even 50%?
Nothing taken out of context here. You very clearly were speaking about amounts of "manmade GHGs" vs "all greenhous gas (GHG)" or you were speaking very unclearly.
No, these were my words, in context, exactly:
If humans stopped or vastly reduced all greenhouse gas (GHG) emmisions immediately- what if the percentage of manmade GHGs turned out to be 2%? On the other hand, what if it turned out to be 20%, or even 50%? Then ask yourself whether in the big picture GHGs even come close to periodic solar fluctuations or other natural sources in causing Global Warming. -BA
First, assign any number you believe to human GHG production, how does that compare to natural GHG production? The human contribution is small compared to GHGs released by natural sources. Now, as I said, compare GHGs (from all sources human and natural) and compare that percentage to other causes of Global Warming, and GHGs are again small compared to, for example, solar activity's effect on Global Warming. Sorry, 6of9, it looks as if your reading comprehension is not quite what you believe it to be.
The earth is in fact always warmed by a blanket of ghg's (one of which is water). Adding to the thickness of that blanket by adding ghg's to the atmosphere will increase that warming. Only an idiot would argue otherwise.
At best, the reference to a blanket is a bad metaphor. Blankets act primarily to suppress convection; the atmosphere acts to enable convection. To claim that the atmosphere acts a blanket, is to admit that you don't know how either one of them operates. It is precisely the amount of GHGs produced by mankind (that you refer to as thickness) that is currently under debate (see previous comment).
