This is an excellent piece of science journalism. It is packed with links and supporting evidence, and it gives a thorough, comprehensive interpretation of the study. It focuses mostly on the evidence that the climate is changing, but it does conclude that man-made greenhouse gas emissions are a factor. It also admits, with proper scientific humility, that "the theory with regard to warming is still incomplete," but this comprehensive evidence seems to make a clear case.

An important report on the NOAA study, but it unnecessarily implies there is a negative shadow in the IPCC data and modeling. Data that shows unarguably that the globe is warming still needs the substantiation of probable cause provided by the IPCC modeling in order to inform policy.

This opinion piece is poor journalism. The author made no effort to study the issue and took government press releases at face value. It is ironic that a picture from Chile is shown, as hundreds already have died in one of the coldest winters on record in Chile, Argentina, Uruguay and southern Brasil. Antarctic ice is at a record high, and last year was also above average. Arctic temperatures are below normal and ice soon will stop melting. The author should have consulted Watts Up With That, an objective, non-governmental source of climate information before copying from press releases.

Made a complex issue into a quick, easy read. The facts stated were both important and either well sourced or universally agreed upon (among deniers and the rest of us). The power of the report was put in context by stating the internal agreement between the three data sets, and also comparing this report to the IPCC.
