Transcript
Climate Change Reconsidered 2009 Report of the Nongovernmental International Panel on Climate Change (NIPCC) Craig Idso, Fred Singer et al. A new 880-page account of climate change science, similar in scope to the science volume of IPCC’s 4th Assessment Report, has just been released. The Report includes summary discussion of relevant and recent scientific publications. NIPCC has been written by an international team of 32 expert scientists from 16 countries, who are independent of political or other allegiances. The report rigorously analyses the IPCC’s claim that dangerous global warming has “very likely” been caused by human greenhouse emissions. Instead of accepting the flawed null hypothesis that observed environmental changes are due to human influence, and citing circumstantial evidence in favour of it, the NIPCC report provides tests for the parsimonious null hypothesis that observed climate changes are natural unless and until evidence to the contrary emerges. Twenty years have elapsed since the formation of the IPCC, yet, despite the expenditure of many tens of billions of dollars and the efforts of hundreds of committed scientists since then, the research summarized in the 4AR IPCC and NIPCC reports provides no evidence that falsifies the null hypothesis of natural climate change. In his comments at the NIPCC report’s launch, Fred Singer (University of Virginia) commented about global warming that “there is no scientific consensus: the science is not settled”. The new report shows that the IPCC has failed to provide any empirical evidence that shows that dangerous human-caused global warming is occurring. In particular: The 20th century was not the warmest in the last 1,000 years; No evidence exists that any measurable amount of the rise in global temperature over the last 50 years is a result of human influence; Current rates of ice/glacier melt are not unusual; Current weather (including tropical storms, droughts and floods) is not unusual; Current sea-level change is occurring at rates typical of recent times; No correlation has been demonstrated between increasing atmospheric carbon dioxide and dangerous temperature rise.
