Chapter 6 compares observations regarding the fate of terrestrial animals to projections made by the IPCC. The IPCC assumes temperatures will rise so rapidly that many animal species will not be able to migrate poleward in latitude or upward in elevation rapidly enough to avoid extinction. New research and observational data ...

Chapter 4 reports the latest observations on changes in the cryosphere, oceans, precipitation, and rivers and streamflow, comparing those observations to projections made by the IPCC. The new research finds less melting of ice in the Arctic, Antarctic, and on mountaintops than previously feared, no sign of acceleration of sea ...

The United Nations’ Intergovernmental Panel on Climate Change (IPCC), already under severe criticism for violating the requirements of academic peer review and relying on secondary sources, comes under attack again in a new report co-produced by three nonprofit research organizations. According to the new report, “natural causes ...

Appendix 2 of Climate Change Reconsidered 2011 Interim Report provides brief bios for the three lead authors and titles and affiliations of eight contributors to the report. ...

Chapter 2 summarizes the latest research on what is known about forcings and feedbacks. While rising levels of atmospheric carbon dioxide (CO 2 ) would increase global temperatures through its thermal radiative properties, all else being equal, all else is not equal. More CO 2 promotes more plant growth both on land and throughout ...

Chapter 10 presents data on the economic effects of the global warming of the twentieth century, errors in how the IPCC conducts its impact analyses, and recent studies concerning biofuels and the relationship between climate and war and social unrest. It finds decades-long empirical trends of improving human well-being according ...

Chapter 7 reviews new research on the effects of rising temperatures and atmospheric CO 2 concentrations on plants and soils. It confirms NIPCC’s earlier finding that plants benefit from both trends and increase the amount of carbon they sequester in woody tissue and root systems. Rising temperatures and atmospheric CO 2 concentrations ...

Chapter 3 reviews the latest research on paleoclimatology and recent temperatures, finding new evidence that the Medieval Warm Period of approximately 1,000 years ago, when there was about 28 percent less CO 2 in the atmosphere than there is currently, was both global and warmer than today’s world. Research also reveals a significant ...

Chapter 8 examines research on the effects of rising temperature and atmospheric CO 2 concentrations on aquatic life. While some corals exhibit a propensity to bleach and die when sea temperatures rise, others exhibit a positive relationship between calcification, or growth, and temperature. The latest research suggests corals and ...

This document is the forward, preface, table of contents, and executive summary of Climate Change Reconsidered 2011 Interim Report. This 400-page compilation of new research on the causes, extent, and consequences of climate change was written and edited by Craig D. Idso, Robert M. Carter, and S. Fred Singer and published by ...

Appendix 1 of Climate Change Reconsidered 2011 Interim Report is a four-page list of acronyms that appear in the body of the report. ...

Chapter 1 of Climate Change Reconsidered 2011 Interim Report describes problems that may be intrinsic to the global climate modeling exercise, followed by more detailed documentation of model shortcomings involving precipitation, temperature, El Niño/Southern Oscillation (ENSO), and soil moisture. We find evidence that the models ...

Chapter 9 finds global warming is more likely to improve rather than harm human health because rising temperatures lead to a greater reduction in winter deaths than the increase they cause in summer deaths. The result is a large net decrease in human mortality. Climate plays a relatively small role in the spread of viral ...

Chapter 5 compares observations concerning extreme weather, such as floods, drought, storms, and hurricanes, to projections made by the IPCC. Researchers have found extreme and destructive rainfall events were more common in many parts of the world during the Little Ice Age than they have been subsequently, contradicting the forecasts ...

ARLINGTON, VA.–There has been increasing concern about global climate change on the part of the media, politicians and the public, stimulated by the idea that human activities may adversely influence global climate, and that government action is required to address this “problem.” My purpose is to show this concern is misplaced ...

In an excerpt from Rational Readings on Environmental Concerns (edited by Heartland Institute Science Director Jay Lehr), S. Fred Singer recounts his experience witnessing certain ideas depart from scientific truth. In particular, Singer focuses on the over-hyped claims of ozone layer depletion, and the hyperactivity this has created ...
