"not supported" is passive voice. Just what percentage of actual -- say,
habitated -- points on the earth is represented by the NASA data? (very
small, close to nil). And, what do we have to compare it to?
Seems to me to be an exercise akin to blind folk describing an elephant.

Your Global Cooling proposition is not supported by the facts as presented
in the following NASA global mean temperature records. You simply cannot
prove a predisposition by cherry picking data to support that position.
The NASA records clearly show that 2007 was actually warmer than 1998.
However, data for the first seven months of 2008 do show a relative cooling,
though these cooler temperatures are still significantly warmer than the
mean average temperature baseline. Rather than miss characterizing this as
"Global cooling, it is best described by "the temperature rise in 2008 has
slowed somewhat"

This presentation seems factual, is very interesting and is well presented
but the conclusions are simply one mans opinion. He does conclude that
warming is a fact but cannot prove or disprove that Co2 increases due to
human activities are a source for this increased warming.
*In conclusion:* your reply does not address the original posting which
reports a newer and more powerful human activity related green house gases.
