JUDITH CURRY: A WEAKER CASE FOR ANTHROPOGENIC GLOBAL WARMING PDF Print E-mail

23 January, 2014: On January 16, Dr. Judith Curry, Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, delivered a powerful statement to the Senate Committee on Environment and Public Works.

Dr. Curry reported that the 5th Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), that was released last fall, weakened the case for Anthropogenic (man-made) global warming in comparison to the 4th Assessment Report of 2007. She pointed out that AR5 acknowledged:

  • Lack of warming since 1998 and growing discrepancies between observations and climate model projections
  • Evidence of decreased climate sensitivity to increases in atmospheric CO2 concentrations
  • Evidence that sea level rise during 1920-1950 was the same as in 1993-2012
  • That Antarctic ice was increasing

Dr. Curry went on to say that the IPCC does not have a convincing explanation for the recent halt in warming.

Dr. Curry stated, "In the U.S., most types of weather extremes were worse in the 1930's and even in the 1950's than in the current climate." She levels strong criticism against the current Climate Action Plan of the Obama Administration. Read her entire statement here.

A SCIENTIFIC CRITIQUE OF THE IPCC'S FIFTH ASSESSMENT REPORT SUMMARY FOR POLICYMAKERS PDF Print E-mail

3 December 2013:  On September 27, the Intergovernmental Panel on Climate Change of the United Nations released Climate Change 2013:  The Physical Science Basis from its Working Group I, including a Summary for Policymakers (SPM). The SPM states, "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century," with "extremely likely" meaning a 95-100% likelyhood of outcome.

But also released in September was Climate Change Reconsidered II: Physical Science (CCR-II), a report from scientists of the Nongovernmental International Panel on Climate Change.  In 1,200 pages and with thousands of references to peer-reviewed papers, the CCR-II refutes the IPCC's Fifth Assessment Report with evidence that natural forces, not man-made forces, drive Earth's climate.

The lead authors of CCR-II, Drs. Robert Carter, Craig Idso, S. Fred Singer, and Willie Soon, have also released a scientific critique of the SPM. The 18-page critique points out that the SPM retreats from 11 previous IPCC alarming claims, contains 13 misleading or untrue statements, and contains another 11 statements that misrepresent important aspects of the science.

The retreats by the IPCC SPM from previous alarming statements may be the most interesting aspects noted by the critique. In the new SPM, the IPCC now admits:

  • That global temperatures have been in a period of "insignificant warming" for the last 15 years, contrary to climate model predications
  • That some multi-decadal time intervals of the Medieval Warm Period (950-1250 AD) were as warm as late 20th century temperatures
  • That Antarctic sea ice has grown since 1979, contrary to model predictions

See the full scientific critique of the SPM here.

IN DEFENSE OF CARBON DIOXIDE PDF Print E-mail

31 May 2013:  Harrison Schmitt, former apollo astronaut and U.S. senator, and William Happer, professor of physics at Princeton University, score a bull's eye with their recent Wall Street Journal article about carbon dioxide.

"Of all of the world's chemical compounds, none has a worse reputation than carbon dioxide. Thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control of energy production, the conventional wisdom about carbon dioxide is that it is a dangerous pollutant. That's simply not the case. Contrary to what some would have us believe, increased carbon dioxide in the atmosphere will benefit the increasing population on the planet by increasing agricultural productivity."  See the rest of the article here.

CLIMATE ALARMISM AND HISTORICAL PRECEDENTS PDF Print E-mail

31 August 2013:  Dr. Richard Lindzen, emeritus professor of atmospheric sciences at the Massachusetts Institute of Technology, recently wrote an excellent article for the fall issue of the Journal of American Physicians and Surgeons.

Lindzen asserts that today's climate science has become a source of authority rather than a mode of inquiry, driven by political agendas. Today's climate science is characterized by:

  • Powerful advocacy groups claiming to represent both science and the public in the name of morality and superior wisdom;
  • Simplistic depictions of the underlying science so as to facilitate widespread "understanding";
  • "Events," real or contrived, interpreted in such a manner as to promote a sense of urgency in the public at large;
  • Scientists flattered by public attention (including financial support) and deferent to "political will" and popular assessment of virtue; and
  • Significant numbers of scientists eager to produce the science demanded by the "public."

 He concludes with the hope that "some path will emerge that will end the present irrational obsession with climate and carbon footprints." Read the rest of the article here.

SUPERB ESSAY BY PROFESSOR BOB CARTER PDF Print E-mail

7 February 2013:  Geologist Bob Carter provides a superb essay on the empirical failure of the hypothesis of dangerous man-made global warming, titled "An Alternative View from Down Under." Professor Carter points out that the hypothesis fails five empirical tests:

1) Large increases in atmospheric warming have failed to produce any global warming over the last 16 years;

2) The magnitude of 20th Century warming falls within the envelope of past natural climate change;

3) Historically, temperature change precedes changes in atmospheric CO2;

4) Global climate model projections of atmospheric and ocean warming are not confirmed by empirical data;

5) Warming of Antarctica and the lower equatorial atmosphere predicted by climate models has not occurred.

Professor Carter's excellent essay can be found here.
