NIPCC: Climate Change Reconsidered II - 2013-2015

The 2013 report by the Nongovernmental International Panel on Climate Change (NIPCC) provides the scientific balance that is missing from the overly alarmists reports of the United Nations' Intergovernmental Panel on Climate Change (IPCC), which are highly selective in their review of climate science. The NIPCC is an international panel of scientists and scholars who first came together in 2003 to provide an independent review of the climate science cited by the IPCC.

The report consists of three parts:

Climate Change Reconsidered II - Physical Science, released in September 2013.

Climate Change Reconsidered II - Biological Impacts, released March 31, 2014

Why Scientists Disagree about Global Warming, released Noverber 30, 2015

The "Physical Science" report finds that negative feedbacks in the climate system reduce the model model derived temperature sensitivity to values an order of magnitude smaller. Earth's surface temperature are largely driven by variations in solar activity, which may have contributed as much as 66% of the observed 20th century warming.

The "Biological Impacts" report finds that rising temperatures and atmospheric CO2 levels are causing “no net harm to the global environment or to human health and often finds the opposite: net benefits to plants, including important food crops, and to animals and human health.”

Some key findings of the Physical Science report:

  • Several important processes are either missing or inadequately represented in climate models. They do not include most natural causes of climate change.
  • Changes in CO2 are frequently seen to lag changes in temperature by several hundred years.
  • The IPCC has greatly overestimated the rise in methane in previous reports.
  • Computer models fail to simulate the magnitude or even the sign of changes of important elements of the climate system, including regional and atmospheric temperatures, precipitation, clouds and winds.
  • The cloud feedback is likely negative, contrary to the models.
  • The IPCC likely underestimates the total cooling effect of natural aerosols.
  • The IPCC claims warming will result in the loss of carbon storage, but empirical evidence shows just the opposite.
  • The Sun may have contributed as much as 66% of the observed twentieth century warming, and
    perhaps more.
  • Current climate models fail to account for a plethora of known Sun-climate connections.
  • Surface-based temperature histories of the globe contain a significant warming bias due to the urban heat island effect.
  • Climate models show an increasing warming trend with altitude, but balloon data shows a slight cooling with altitude in the tropics.
  • Earth’s climate has both cooled and warmed independent of its atmospheric CO2 concentration.

Some key findings of the Biological Impacts report:

  • Elevated atmospheric CO2 has a fertilization effect which promotes plant growth.
  • The ongoing rise in the air’s CO2 content is causing a great greening of the Earth.
  • Rising temperatures and atmospheric CO2 levels play a key role in increasing crop yields.
  • Ecosystems have thrived throughout the world as a result of warming temperatures.
  • Marine life has shown considerable tolerance to temperatures and CO2 values predicted for the next few centuries, and many show positive responses to lowering pH levels.
  • A modest warming of the planet will result in a net reduction of human mortality.
