Somebody must have a skewed dataset somewhere on average global temperatures.

Global satellite temperatures
The original satellite data showed a vast discrepancy between satellite measurements and what global warming models would predict. However, it was discovered that some of the satellite calibrations were wrong, so the data was adjusted. Figure 12 presents the corrected satellite data.39 Satellite data from the troposphere does confirm that it is warming, although the rate is about half of that measured from ground-based instruments. The stratosphere is cooling, although scientists believe that much of that is due to depletion of ozone in the atmosphere.40

Here is the data I'm looking at..

The climate sceptics are flogging a dead horse

The argument should be what parameters should be studuied rather then whether the planet is warming or not. Nitrogen compounds, atmospheric water vapour, and methane are also candidates for global warming. The warming of land masses and the sea will bring into play all sorts of other carbon generating gases, the biomass that is currently in the permafrost and the ocean floor.
Methane hydrate exists in vast quantities beneath the ocean floor and is believed to constitute the largest reservoir of organic carbon on Earth.

"It is well documented that bottom-water temperatures in the ocean increase by approximately 5 degrees centigrade during periods of global warming," Hornbach says. "Our study indicates that perhaps as much as 2,000 gigatons (a single gigaton is one billion tons) of methane gas might escape from the ocean into the atmosphere during such warming events."
By comparison an earlier link indicates that 190 billion tons of CO2 is produced annually from all sources. Human production of CO2 is only 6 billion tons anually BUT we are seeing an increase in CO2 levels, indicating we might be upsetting a delicate balance. i.e. the "steady state" acion of CO2 gas being generated/absorbed has been knocked to one side by human activity. This would include things like farming, deforestation as well as the burning of fossil fuels.
Venus is a good example of what happens to a planet when greenhouse gases get out of control..

One last paragraph from godandscience.org link..
Consequences of global warming Temperature variations of the earth are highly dependent upon land and ocean configuration. Two thirds of the earth's land resides in the northern hemisphere. Because oceans tend to moderate temperatures (Figure 14A), temperature changes in the southern hemisphere tend to be more moderate than those in the northern hemisphere (Figure 14B). So, global warming will primarily impact the northern hemisphere, as seen in Figure 5. Without drastic changes, CO2 levels will double within 150 years, and possibly quadruple eventually. These high CO2 levels were seen during the Mid-Cretaceous period of the earth's history, and many species thrived during that time. However, since then, solar luminosity has increased by 0.7%. Although this doesn't seem like a lot, but it would mean that temperatures would be much warmer than those of that era.
Basically, we don't want to go there imho. The time to start altering course is now.
