By Mark S. Lawson, published 17/4/2008The argument is if human activity has added to the current, natural warming cycle: and if it hasn't then why spend up big on carbon trading?

However I must take you to task about your interpretation of the science.
Since a boomer year in 1998 solar forcing has been dropping. As a major player in global temperatures you would expect the trend of global temperatures to fall as well. However this is not the case, although warming has slowed somewhat as a result. (Unless you're the type of chap who might claim the globe has cooled because you have fudged the averages to produce the result you want http://www.skepticalscience.com/Global-warming-stopped-in-1981.html).
Rhamstorf concludes "Overall, these observational data underscore the concerns about global climate change. Previous projections, as summarized by IPCC, have not exaggerated but may in some respects even have underestimated the change, in particular for sea level" http://pubs.giss.nasa.gov/docs/2007/2007_Rahmstorf_etal.pdf
This is consistent with his observations "Carbon dioxide concentration follows the projections almost exactly..."
And
"The global mean surface temperature increase (land and ocean combined) in both the NASA GISS data set and the Hadley Centre/Climatic Research Unit data set is 0.33°C for the 16 years since 1990, which is in the upper part of the range projected by the IPCC. Given the relatively short 16-year time period considered."
The "embedding period of 11 years" I believe is a statistical reference beyond my ken as well.
The next time you ask some "Australian scientists", try to include Dr Barrie Pittock. http://www.publish.csiro.au/pid/4992.htm
Again thanks for the article. Nice to see some non-inflammatory discussion from the other side of the fence for a change. Keep it up.
