I have been reading the latest paper by NASA GISS and which provides more evidence of AGW. This is the draft that was released on the 19th March.

The report addresses the problems that the scientists face in releasing their data:

One lesson we have learned is that our approach of making our global data analysis immediately and routinely available, with data use by ourselves and scientific colleagues helping to reveal potential flaws of the input data, has a practical disadvantage: it allows any data flaws to be interpreted as machinations.

The report concludes:

The reality of continued global warming contrasts sharply with a frequently heard assertion that the world has been in a cooling trend for the past decade or at least "global warming stopped in 1998." Of course it is possible to find almost any trend for a limited period via judicious choice of start and end dates, but that is not a meaningful exercise. In a wiser assessment, Solomon et al. [2009] write "the trend in global surface temperature has been nearly flat since the late 1990s despite continuing increases in the forcing due to the sum of the well- mixed greenhouse gases." But is even that assertion correct?

Climate trends can be seen clearly if we take the 60-month (5-year) and 132-month (11- year) running means, as shown in Figure 21 for data through January 2010. The 5-year mean is sufficient to minimize El Nino variability, while the 11-year mean also minimizes the effect of solar variability. We conclude that there has been no reduction in the global warming trend of 0.15-0.20°C/decade that began in the late 1970s.

Here is figure 21.

AGW is not going away, and no matter how hard those who deny AGW try. The data keeps confirming the theory of AGW.

Here is the latest graph (from 10th Feb) that some used to use to support their "not warming since 2000" meme, which they now conveniently fail to show when the trend is once more heading up.
