"The was a lot of speculation last year that our global temperature would recover from the huge drops last spring. While there has been some recovery, the overall global temperature trend since 1999 has been the subject of much debate. What is not debatable is that the current global temperature anomaly, as determined by a leading authority on global satellite temperature measurements, says we have no departure from “normal” this month. Given the U.S. Senate is about to vote upon the most complex and costly plan to regulate greenhouse gases, while the EPA suppresses earlier versions of the chart shown below from a senior analyst, this should give some pause to those who are rational thinkers. For those that see only dogma, I expect this will be greeted with jeers. – Anthony"

It doesn't seem like it's possible that there has been much increase in global temperature caused by human activity. Which is also another way to say that if we wanted warmer global temperature- putting CO2 into the atmosphere would not work very well in increasing global temperature.

If we were terraforming Earth or some other planet adding CO2 doesn't seem to do much. Of course if we were putting some effort into putting CO2 into the atmosphere, one might point out the problem that you have all this plant life interfering with the effort.

Though I suppose there is the Hope in the faith of AGW, if you assign a significant influence of the low sunspot activity, plus throwing in some other nature variability.
Doubtlessly it seems the world of wandering around in waders and eating people may have to be delayed a bit.
