I think you misconstrued so I'll reiterate. Forgive me if this sounds condescending.
The sun is constantly adding energy (note that I did not mention such a violation of the laws of physics as creation of energy) to the system (Earth). Normally, a lot of the energy added by the sun is reflected back into space. Greenhouse gasses such as CO2, CH4, etc. suspended in the atmosphere act as a mirror, reflecting that energy back toward the Earth. This retained energy, in the form of heat, is now trapped within the system thereby increasing the overall energy of the system, and leading to a decline of stability (again, the name 'global warming' is silly). This increase in instability can lead to larger gradients between different areas of the system (ie: the point brought up earlier about Antarctica becoming colder, a point which my friends at McMurdo station can wholeheartedly endorse).
As far as issues with weather recording stations--If these weather stations were held to such strict criteria, then we would have to throw out all of the data ever gathered around major metropolitan areas, like Atlanta, because the pavement will affect your readings.
The amount of data collected by these weather stations is extraordinary. we're talking millions (if not billions) of data points per station, so if say somebody chopped down a tree next to one in 1964, that sheer mass of data would overwhelm the difference. The weather stations I've encountered in my travels over three continents have all held to a pretty reliable standard, which is easily discerned as no other structure on the planet is built on stilts, seven feet high, painted white, and looking like a well-roofed birdhouse.
This brings up another point which I've found fascinating: statistics are full of shit. dead serious, Statistics are so silly, I can take the exact same demographic data, hand it to two statisticians, and get completely different answers.
I will say this about that graph--there is no R^2 value. R^2 indicates a margin of error in regard to the data, and will tell you how far a researcher has his head shoved up his fourth point of contact.
Here's some of my recent work as an example.
Note the R^2 value, and the margin of error between the trend line and my data points. Some of the statistics(read: bullshit) people throw around nowadays have R^2 values of less than ten percent. Compare that to how much of a difference there is at less than 77%.
sorry, bit of a tangent there. Anywho.
I'm not an expert in Atmospherics, so you're going to have to shoot me some links so that I can check the peer-reviewed articles regarding such phenomena. But if I follow you correctly, riddle me this: have you ever hit a mirror with a high-powered laser? Greenhouse gasses function as such by reflecting energy back to the earth. While they may absorb some of that energy, the amount would have little effect compared to the energy that they reflect, which is then absorbed by the oceans or landmass below.
True, Earth does go through natural cycles, and 99 point something percent (sorry I don't have an R^2 value for that) of all greenhouse gasses are produced naturally by volcanoes and farts. However, the small amount of greenhouse gasses that humans produce can have catastrophic second and third-order effects by pushing what may have been a normal warming trend into high gear. Doing so has the potential to release CH4 stored in the arctic tundra.
That's a very bad thing. Like "we as a species may not survive the ten years that it would take for the CH4 to work its way out of the atmosphere' bad.
As for wikileaks and other such nonscientific topics, that's not my realm, nor am I inclined to muddle in such things. I've heard of such falsification of temperature data, and IF the allegations are true, those scientists should be skullraped in no uncertain terms.
Cars: funny thing about those 'ecofriendly' 50,000 dollar cars is that they're just as ecologically unsound, if not moreso than a standard vehicle. This is where smart people need to come in and bring a garbage truck full of good ideas.
As far as profit benefits, I'm more concerned with things like having a mountain come down on my head the next time I'm sheep hunting because the permafrost has grown too weak to hold a whole mountainside up.

The above happened while I was a park ranger. NPS made a very big stink about it.

These are happening all over the state. Not to mention that nearly every glacier is in massive retreat (except for Taku and a few other freaks), and the spruce trees are on a slow but sure march north. Things are changing, and it doesn't really matter whether we have a hand in it or not. How we deal with it does.
Here's the cost/benefit analysis that I think will underline my point.
If you are right, and we changed our habits just-in-case, we will have retooled our economy to rely less on fossil fuels. If you're right, and we do nothing, then no harm done.
If I am right, and we do something about it, then we survive. If I am right, and we do nothing, then our civilization will be *at least* severely damaged, with climate-related catastrophes wiping out massive swaths of our population
I'd personally rather stay on the cautious side when it comes to billions of lives and thousands of species. Besides, why should we not try to keep our house clean and improve our technology?
