The Nongovernmental International Panel on Climate Change (NIPCC), a coalition of the Center for the Study of Carbon Dioxide and Global Change, Science and Environmental Policy Project (SEPP), and The Heartland Institute has just released its new volume of real climate science that opposes the science fiction of the UN’s IPCC. The documents can be obtained from the NIPCC main website: http://climatechangereconsidered.org/
Last fall they released a report on the physical science of climate change. That report may be downloaded as a Summary for Policy Makers (22 pages) and CCR-II Physical Science (Ca. 1,000 pages, 20Mb) are available for free download. I summarized this report in a previous post.
The new report concerns the biological impact of climate change. The full report is more than 1000 pages (19.5Mb) and available here:
There is a 20-page Summary for Policy Makers here:
Later this month, NIPCC will publish another volume concerning human welfare, energy, and policies.
Below are very brief summaries of these two volumes, physical science and biological impacts taken from the Summary for Policy Makers:
Physical Science Summary
• Global climate models are unable to make accurate projections of climate even 10 years ahead, let alone the 100-year period that has been adopted by policy planners. The output of such models should therefore not be used to guide public policy formulation.
• Neither the rate nor the magnitude of the reported late twentieth century surface warming (1979–2000) lay outside the range of normal natural variability, nor were they in any way unusual compared to earlier episodes in Earth’s climatic history.
• Solar forcing of temperature change is likely more important than is currently recognized.
• No unambiguous evidence exists of dangerous interference in the global climate caused by human-related CO2 emissions. In particular, the cryosphere is not melting at an enhanced rate; sea-level rise is not accelerating; and no systematic changes have been documented in evaporation or rainfall or in the magnitude or intensity of extreme meteorological events.
• Any human global climate signal is so small as to be nearly indiscernible against the background variability of the natural climate system. Climate change is always occurring.
• A phase of temperature stasis or cooling has succeeded the mild warming of the twentieth century. Similar periods of warming and cooling due to natural variability are certain to occur in the future irrespective of human emissions of greenhouse gases.
Biological Impacts Summary
• Atmospheric carbon dioxide is not a pollutant. It is a non-toxic, non-irritating, and natural component of the atmosphere. Long-term CO2 enrichment studies confirm the findings of shorter-term experiments, demonstrating numerous growth-enhancing, water-conserving, and stress-alleviating effects of elevated atmospheric CO2 on plants growing in both terrestrial and aquatic ecosystems.
• The ongoing rise in the air’s CO2 content is causing a great greening of the Earth. All across the planet, the historical increase in the atmosphere’s CO2 concentration has stimulated vegetative productivity. This observed stimulation, or greening of the Earth, has occurred in spite of many real and imagined assaults on Earth’s vegetation, including fires, disease, pest outbreaks, deforestation, and climatic change.
• There is little or no risk of increasing food insecurity due to global warming or rising atmospheric CO2 levels. Farmers and others who depend on rural livelihoods for income are benefitting from rising agricultural productivity throughout the world, including in parts of Asia and Africa where the need for increased food supplies is most critical. Rising temperatures and atmospheric CO2 levels play a key role in the realization of such benefits.
• Terrestrial ecosystems have thrived throughout the world as a result of warming temperatures and rising levels of atmospheric CO2. Empirical data pertaining to numerous animal species, including amphibians, birds, butterflies, other insects, reptiles, and mammals, indicate global warming and its myriad ecological effects tend to foster the expansion and proliferation of animal habitats, ranges, and populations, or otherwise have no observable impacts one way or the other. Multiple lines of evidence indicate animal species are adapting, and in some cases evolving, to cope with climate change of the modern era.
• Rising temperatures and atmospheric CO2 levels do not pose a significant threat to aquatic life. Many aquatic species have shown considerable tolerance to temperatures and CO2 values predicted for the next few centuries, and many have demonstrated a likelihood of positive responses in empirical studies. Any projected adverse impacts of rising temperatures or declining seawater and freshwater pH levels (“acidification”) will be largely mitigated through phenotypic adaptation or evolution during the many decades to centuries it is expected to take for pH levels to fall.
• A modest warming of the planet will result in a net reduction of human mortality from temperature-related events. More lives are saved by global warming via the amelioration of cold-related deaths than those lost under excessive heat. Global warming will have a negligible influence on human morbidity and the spread of infectious diseases, a phenomenon observed in virtually all parts of the world.
