How Credible Is The IPCC Climate Reporting?

The Non-Intergovernmental Panel on Climate Change (NIPCC) has issued their 2013 report “Climate Change Reconsidered II-Physical Science”.  This report, a Summary for Policy Makers (SMP), challenges the data within the IPCC’s SMP scheduled for release this month.

Let’s contrasts the two reports.  The NIPCC science is empirical data based.  The IPCC also includes empirical data but their methodology relies heavily  on computer based guesses projections,  the scientific conclusion are revised to satisfy political objectives and the IPCC is not home to scientists that want to submit studies that contradict the message that global warming is man-made.  NIPCC says this about the IPCC: “The hypothesis implicit in all IPCC writings, though rarely explicitly stated, is that dangerous global warming is resulting, or will result, from human-related greenhouse gas emissions.”   They start with a conclusion and look for studies that support the conclusion.  That’s not the the scientific method.

Confirming NIPCC stated view about the IPCC methodology of demonstrating that warming is man made and no other opinions are welcome, here is a posting from the  UK Mail on line:

“World’s top climate scientists told to ‘cover up’ the fact that the Earth’s temperature hasn’t risen for the last 15 years”.   From the posting we get this:  “But leaked documents seen by the Associated Press, yesterday revealed deep concerns among politicians about a lack of global warming over the past few years.

Germany called for the references to the slowdown in warming to be deleted, saying looking at a time span of just 10 or 15 years was ‘misleading’ and they should focus on decades or centuries.

Hungary worried the report would provide ammunition for deniers of man-made climate change.

Belgium objected to using 1998 as a starting year for statistics, as it was exceptionally warm and makes the graph look flat – and suggested using 1999 or 2000 instead to give a more upward-pointing curve.

The United States delegation even weighed in, urging the authors of the report to explain away the lack of warming using the ‘leading hypothesis’ among scientists that the lower warming is down to more heat being absorbed by the ocean – which has got hotter.

Because investigations that disprove manmade global warming are unwelcome and that the politicians influence the final report, it is difficult to understand how a rational person, scientist or not, can have confidence that the IPCC reports.

It is a nice piece of work. Read it.

    About 7000 years ago there was a climatic optimum and the sea level was much higher than it is today. On the other hand about 12000 years ago an ice sheet roughly a mile thick covered North America. The present site of New York was under this sheet of ice. Geologists are well aware that climate change has natural causes.
