It turns out that it is also an appropriate graph to post following the Trend and Variation video clip posted by Iamwhomiam. It's the long term 1880 - 2009 temperature trend (HADCRUT).
Note that the green trend line shows a linear warming increase of about 0.8 degrees Celsius over 130 years which works out at an average 0.006 degrees per year. If this trend continues, then it will mean an addition of another 0.6 degrees C by the end of the 21st century.
However AGW projections based on their computer climate modelling, projected 22 years ago, that global temperatures would see accelerated warming, and it hasn't happened. It doesn't show on this graph. Also please note on this graph that from the year 1998, actual temperature against the trend line has been converging meaning that there has not been a warming trend for the last ten years of the graph..

But beyond the copy and paste of graphs here, the WSJ opinion piece itself is solid evidence that AGW accelerated global warming is not happening.
Reflect on this, the sixteen persons behind the article are all eminent in their fields, so one would expect that they would not put their name to this article unless they were sure of their facts. This would include having studied the relevant data and information concerning global temperatures for the periods to which they refer. Just focusing on two of the points raised, the first is the fact that there has been a lack of global warming for well over 10 years now, and the second is that there has been smaller-than-predicted warming over the 22 years since the U.N.'s Intergovernmental Panel on Climate Change (IPCC) began issuing projections.
Imo, they are better placed and informed than myself or anyone else here on this matter, so unless someone can show evidence that they are all shills for big oil, liars, lack the smarts, etc., then it is reasonable to accept the facts as stated.
