Climate Change Reconsidered

Nongovernmental International Panel on Climate Change (NIPCC) has released an 880-page book challenging the scientific basis of concerns that global warming is either man-made or would have harmful effects.

Climate Change Reconsidered
June 2, 2009

Coauthors Dr. S. Fred Singer and Dr. Craig Idso and 35 contributors and reviewers present an authoritative and detailed rebuttal of the findings of the IPCC.

A couple highlights include:
"We regret that many advocates in the debate have
chosen to give up debating the science and focus
almost exclusively on questioning the motives of
“skeptics,” name-calling, and ad hominem attacks."

"The IPCC continues to undervalue the
overwhelming evidence that, on decadal and centurylong
time scales, the Sun and associated atmospheric cloud effects are responsible for much of past climate
change. It is therefore highly likely that the Sun is
also a major cause of twentieth-century warming,"

"The scholarship in this book demonstrates overwhelming scientific support for the position that the warming of the twentieth century was moderate and not unprecedented, that its impact on human health and wildlife was positive, and that carbon dioxide probably is not the driving factor behind climate change."

"the contributors and reviewers of NIPCC donated their time and best efforts to produce this report out of concern that the IPCC was provoking an irrational fear of anthropogenic global warming based on incomplete and faulty science."

"Seeing science clearly misused to shape public policies that have the potential to inflict severe economic harm, particularly on low-income groups, NIPCC’s team of scientists chose to speak up for science at a time when too few people outside the scientific community know what is happening, and too few scientists who know the truth have the will or the platforms to speak out against the IPCC."

Chapter 1 describes the limitations of the IPCC’s
attempt to forecast future climate conditions by using
computer climate models.

Chapter 2 describes feedback factors that reduce
the earth’s temperature sensitivity to changes in
atmospheric CO2.

Chapter 3 reviews empirical data on past
temperatures. We find no support for the IPCC’s
claim that climate observations during the twentieth
century are either unprecedented or provide evidence
of an anthropogenic effect on climate.

Chapter 4 reviews observational data on glacier
melting, sea ice area, variation in precipitation, and
sea level rise. We find no evidence of trends that
could be attributed to the supposedly anthropogenic
global warming of the twentieth century.

Chapter 5 summarizes the research of a growing
number of scientists who say variations in solar
activity, not greenhouse gases, are the true driver of
climate change.

Chapter 6 investigates and debunks the
widespread fears that global warming might cause
more extreme weather.

Chapter 7 examines the biological effects of
rising CO2 concentrations and warmer temperatures.

Chapter 8 examines the IPCC’s claim that CO2-
induced increases in air temperature will cause
unprecedented plant and animal extinctions, both on
land and in the world’s oceans. We find there little
real-world evidence in support of such claims and an
abundance of counter evidence that suggests
ecosystem biodiversity will increase in a warmer and
CO2-enriched world.

Chapter 9 challenges the IPCC’s claim that CO2-
induced global warming is harmful to human health.............
However, a thorough examination of the
peer-reviewed scientific literature reveals that further
global warming would likely do just the opposite and
actually reduce the number of lives lost to extreme
thermal conditions.............
