Major reports are pointing to proof of global warmingUnited States

He has held science-related positions with private-sector companies and currently is president of a think tank focusing on global climate change.
Recent comments in The World-Herald remind us of deniers’ tenacity in ignoring scientific evidence of anthropogenic — human-caused — global warming.
Pulse writers have suggested that I “gave no facts” in my July 7 letter to support my statement that there is a 90 percent certainty of current warming being both real and anthropogenic.
I listed the IPCC (Intergovernmental Panel on Climate Change) 2007 report prepared by more than 1,000 scientific reviewers from all over the world and corroborated by government scientists of all the individual contributing countries.
I also listed “The Copenhagen Diagnosis,” published in 2009, with 26 international scientific authors, and I cited publications by five of the world’s most highly acclaimed individual climate scientists.
Scientific evidence supporting what Pulse writers called my “contention” is overwhelming — too extensive, in fact, to present in a World-Herald article. IPCC took 996 pages to summarize it in its first volume (“Climate Change 2007: The Physical Science Basis.”) And volumes 2 and 3 of the IPCC 2007 report continue summarizing anthropogenic warming for another 976 pages. and 850 pages respectively.
More recent supporting evidence may be found in the NOAA (National Oceanographic and Atmospheric Administration) 2009 State-of-the-Climate report. It was released last Wednesday and was prepared by more than 300 scientists from 160 research groups in 48 countries. The report states, “Global warming is undeniable.”
Although one local denier claimed “the science won’t be settled until an independent, impartial panel of scientists reviews all of the data,” that suggestion belies the existence and mission of both IPCC and NOAA. IPCC and NOAA are those panels, and NOAA’s 2009 report corroborates IPCC’s 2007 findings.
IPCC was established jointly in 1988 by the United Nations and World Meteorological Organization (WMO) to perform exactly such a review every six years. The panel’s most recent, fourth report was in 2007, and its three volumes totalled 2,822 pages.
The 2007 IPCC report and “The Copenhagen Diagnosis” can provide readers with a summary of evidence supporting my statements about the unequivocal reality and current anthropogenic origins of global warming due to human-caused rises in atmospheric greenhouse gas levels.
Those reports cite a 90 percent probability that continued greenhouse gas emissions at or above current rates will make global warming worse in the 21st century.
The United Nations and WMO panel — IPCC — involved scientists from around the world who worked for six years to produce 2,822 pages of review, as the 2007 IPCC report notes. Local denier attempts to wave aside this panel and its comprehensive report simply don’t wash. The IPCC 2007 report stands firm.
“The Copenhagen Diagnosis” provided information updates in 2009, with the same conclusions being reinforced.
Current warming is real and anthropogenic. That’s established with 90 percent certainty, a statistic published in both reports, and this is essentially “as good as it gets” for complex scientific issues.
We should move on now to the more important topic of how to stop global warming before it accelerates beyond control.
