?We could be coming out of the colder
phase and into a warmer phase of the
cycle right now. .. It?s probably fair to

say that we?re seeing a component of

natural variability?

Dr. Gerard Bond, Lead Researcher, Lamont
Doherty Earth Observatory, The New York Times,
November 18, 1997.

?Global warming is not proven.?

Sir John Mason, Chair, Graduate School of
Environment, Imperial College?s Center for
Environmental Technology, Reuters World Service,
July 15, 1997.

?The simple fact is that today?s computers
still cannot replicate what is already
known about climate changes over the
past 50 years. When given data on
climate that is a matter of historical
record, the models do not reach the
correct result?

Dr. Edgar Berkey, President, Center for Hazardous
Materials Research, and Member of the US.
Environmental Protection Agency Science Advisory
Board, Dayton Daily News, June 9, 1997.

believe there is still great uncertainty
about the climate system response to
increasing levels of greenhouse gases.?

Dr. Roy Spencer, Meteorologist and Team Leader,
NASA Marshall Space Flight Center, Investor?s
Business Daily, October 6, 1997.

?Understanding the current state of the
polar ice sheets is critical for determining
their contribution to sea-level rise and
predicting their response to climate
change. Current estimates from decades
of tide-gauge data indicate an increase in
global sea level of 10 to 20 cm. over the
past century. It is uncertain, however;
what the individual contributions of the
polar ice sheets are to sea-level rise at
this time.?

Curt H. Davis, Department of Electrical Engineering,

University of Missouri; Craig A. Kluever, Department
of Mechanical and Aerospace Engineering, University
of Missouri; and Bruce J. Haines, Jet Propolsion
Laboratory, California Institute of Technology, Science,
Vol. 279, March 27, 1998

?Yes, there have been these big
climate changes. But I think they?re
all natural.?

Dr. William Gray, Climatologist, Colorado
State University, The New York Times,
September 7, 1997.

?In our view, the NRC [National
Research Council] panel seriously
underestimates the research e??ort
required to reduce the uncertainty in
the aerosol forcing to the specified
In the absence of this research,
knowledge of climate response to
greenhouse forcing necessary for
confident policymaking will be reliant
entirely on climate models having
little credible empirical confirmation.?

Dr. Stephen E. Schwartz, Atmospheric Chemist,
Brookhaven Institute; and Dr. Meinrat O. Andrene,
Biogeochemist, Max Planck Institute, Science, Vol.
272, May 24, 1996.

?We figure half the climate change
from 1850 to now can be accounted
for by the sun.?

Dr. Judith Lean, Solar Physicist, Naval
Research Laboratory, The New York Times,
September 23, 1997.

?The temperatures we measure from
space are actually on a very slight
downward trend since 1979 in the
lower troposphere. We see major
excursions due to volcanic eruptions
like Pinatubo, and ocean current
phenomena like El Nirio, but overall
the trend is about 0.05 degrees Celsius
per decade cooling.?

Dr. Roy Spencer, Meteorologist and Team Leader,
NASA/Marshall Space Flight Center,
NASA/Marshall Space Flight Center Web Site,
February 6, 1997.

here isn?t a big case being made for
the detection of greenhouse warming.?

Dr. Brian Farrell, Professor of Meteorology, Harvard
University, The Washington Times, July 1, 1997.

 

 

?21s you increase CO2 [in the
atmosphere], you don?t see any
increase in El Nirios.?

Dr. Tim Barnett, Intergovernmental Panel on
Climate Change, Working Group I, Chapter 8, lead
author on ?Detection of Climate Change and
Attribution of Causes,? and Climatologist, Scripps
Institute of Oceanography, The Washington Post,
September 21, 1997.

?There?s always a chance that what
we?re seeing happening is happening
for natural 

Dr. Kevin Trenberth, Climatologist, National Center
for Atmospheric Research, Associated Press,
October 6, 1997.

r?Some individuals will interpret the 
recent upswing in hurricane activity

during 1995 and 1996 and the

expected normal activity as evidence

of climate changes due to increased

man-made greenhouse There

is no reasonable way such an

interpretation can be accepted.?

Dr. William Gray, Climatologist, Colorado State
University, Update, Vol. 10, No. 7, June 1997.

believe we have a decade or so in
which we can collect data and refine
our models before we have to act.?

Dr. Gerald North, Chairman, Texas 
Department of Meteorology, Cincinnati Enquirer,
October 25, 1997.

?Scientists and laypersons have a
predilection for deterministic
explanations of climate variations.
However; climate can vary chaotically,
in the absence of any forcing. ..
The slightest alteration of initial or
boundary conditions changes the
developing patterns, and thus next
year?s weather is inherently
unpredictable.?

Dr. James Hansen, NASA Goddard Institute for
Space Studies, and 42 others, Journal of
Geophysical Research, Vol. 102, No. D22,
November 27, 1997.
