When I read about anthropogenic warming, I see that a majority of scientists believe it is a cause, even perhaps THE cause. The article you link says "The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years." But I've seen others (granted, in the small minority) that claim human-based sources may contribute to the current warming trend, but that other, natural sources produce more CO2 than human sources.
As the abiotic origin of oil and other petroleum fuels show, scientists can be wrong en masse. NASA, although contributing to data and analysis, certainly, is following the lead of the majority of scientists. And I can understand that.

"From the early Triassic to the middle Cretaceous, the concentration of atmospheric Carbon Dioxide was similar to its current density. From the late cretaceous to the early Miocene, the concentration climbed above 210 ppmV. During the Holocene period, the concentration has oscillated from 210 ppmV to 385 ppmV.
It is possible that the concentration of atmospheric CO2 will increase normally in the course of the next 50 million years to 1050 ppmV or 2500 ppmV."
NASA's chart only went back some 400,000 years, which does not include the bigger cycles over millions of years. I've seen many, many papers on climate change over longer periods and my feeling, granted as a complete layman, yet well-read, is that what's happening is mostly natural and there's not really anything we can do about it.
Also, as many of these papers state - flora grows much better, faster and bigger in CO2-rich environments. I've also seen other papers that claim that CO2 is not such an energy-trapper as has been stated. It's one of the reasons the dinosaurs could grow so big - plenty of food for herbivores, which also means plenty of food for omnivores and carnivores. Warming won't necessarily be a bad thing for the planet, although us puny humans with water-front property may not like some of the changes.
Your proclivity to put forward arguments of dubious validity, beat your chest and proclaim how well read you are, then disappear at the first whiff of a debate only to reappear sometime later with those same dubious beliefs intact is...
...wait, I know there's a word for this...
...that's it!! ...
