Concerns On The IPCC Report:
The Actual State
Of Climate Science
Roger A. Pielke Sr.
University of Colorado, CIRES, Boulder, CO
Conference with Respect to the United Nations
Climate Change Conference (COP 15)
Copenhagen, Denmark
6 December 2009
Human-Caused Climate
Change Has Become One Of
The Highest Political
Priorities in the United
States and Worldwide
“Climate change is a clear and
present danger to our world that
demands immediate attention.
Facts on the ground are
outstripping worse-case scenario
models that were developed only a
few years ago.”
Secretary of State Hillary Clinton

http://www.cnn.com/2009/POLITICS/04/27/us.global.warming/
My Conclusion
I agree that there is no question
that human activity is resulting in
an increase in the atmospheric
concentration of greenhouse gases
including carbon dioxide [CO2]
Science Organizations Remind
Senators of the Consensus on
Climate Change”
“Observations throughout the world
make it clear that climate change
is occurring, and rigorous scientific
research demonstrates that the
greenhouse gases emitted by
human activities are the primary
driver.
http://www.agu.org/journals/eo/eo0944/2009EO440008.pdf#anchor
Hypothesis #1
• The
human
influence
on
climate
variability and change is of minimal
importance, and natural causes dominate
climate variations and changes on all
time scales. In coming decades, the
human influence will continue to be
minimal
Hypothesis #2
• Although the natural causes of climate
variations and changes are undoubtedly
important, the human influences are
significant and are dominated by the
emission of greenhouse gases into the
atmosphere, the most important of
which is carbon dioxide. The impact of
these gases on regional and global
climate constitutes the primary climate
issue for the coming decades
Hypothesis #3
• Although the natural causes of climate
variation and changes are undoubtedly
important,
human
influences
are
significant and involve a diverse range
of first-order climate forcings, including,
but not dominated by the human input
of CO22. Most, if not all, of these human
influences on regional and global
climate will continue to be of concern
during the coming decades.
Only ONE of these
hypotheses can be correct
Important Findings
• Climate Variability and Change Are
Much More Than Global Warming or
Cooling
• Even with Global Warming only about
25-30% (my analysis), 40% (Shindell
et al. 2009) or 58% (the IPCC view) is
from CO22

[http://www.climatesci.org/publications/presentations/PPT-69.pdf]
• Humans Produce Both Global Warming
and Global Cooling Forcings

Conclusion:
Most locations in south and central
Florida are drier and warmer today
than they would be under the same
large-scale weather patterns prior to
the 20th century due just to
landscape change.

In Matsui and Pielke Sr. (2006), it was found
from observations of the spatial distribution
of aerosols in the atmosphere in the lower
latitudes, that the aerosol effect on
atmospheric circulations, as a result of their
alteration in the heating of regions of the
atmosphere, is 60 times greater than due to
the heating effect of the human addition of
well-mixed greenhouse gases.

Extensive peer-reviewed research has
shown that the focus on just carbon
dioxide as the dominate human climate
forcing is too narrow.
Hypothesis #1 and #2 are refuted
Natural variations are important, and
also, the human influence is significant,
but it involves a diverse range of firstorder climate forcings, including, but
not limited to the human input of
greenhouse gases including CO2
These other forcings, such as
land-use change and from
atmospheric pollution aerosols,
may have a greater effect on
our climate than the effects
that have been claimed for CO2
The acceptance of CO2 as a
pollutant by the EPA , yet it is a
climate forcing not a traditional
atmospheric pollutant, opens up a
wide range of other climate
forcings which the EPA could
similarly regulate (e.g., land use,
water vapor).
What Does The Other Climate
Data Tell Us?
1) There is no regional predictive
skill by the multi-decadal global
models decades into the future;
2) Even the global average climate
metrics, such as global warming,
are not being accurately
predicted by these models
Koutsoyiannis, D., A. Efstratiadis, N. Mamassis, and A.
Christofides, On the credibility of climate predictions,
Hydrological Sciences Journal, 53 (4), 671–684, 2008.
"Geographically distributed predictions of future
climate, obtained through climate models, are widely
used in hydrology and many other disciplines, typically
without assessing their reliability. Here we compare
the output of various models to temperature and
precipitation observations from eight stations with
long (over 100 years) records from around the globe.
The results show that models perform poorly, even at
a climatic (30-year) scale. Thus local model projections
cannot be credible, whereas a common argument that
models can perform better at larger spatial scales is
unsupported."

Conclusion:
There is a significant amount of real
world data that conflicts with the
findings in the 2007 IPCC report
Why Has Hypothesis #3 Not
Received Attention?
A main reason for the failure to
accurately communicate climate
science to the policymakers is a
result of the real conflict of
interest among the leadership of
the climate community.
The IPCC and CCSP assessments,
as well as the science statements
completed by the AGU, AMS,
and NRC, are completed by a small
subset of climate scientists who are
led by the same individuals. They
are evaluating the robustness of
their own research.

How Do We Move
Forward?
POLICYMAKERS SHOULD LOOK FOR WINWIN POLICIES IN ORDER TO IMPROVE
THE ENVIRONMENT WE LIVE IN
The costs and benefits of the regulation of the
emissions of CO22 into the atmosphere need to
be evaluated together with all other possible
environmental regulations. The goal should be
to seek politically and technologically practical
ways to reduce the vulnerability of the
environment and society to the entire spectrum
of human-caused and natural risks.

To Move Forward We Need A
Bottom-Up Resource Based
Focus, Rather Than Relying On
Downscaling From Global
Climate Models
RECOMMENDATIONS
¾ National and International climate assessments
should be written by climate scientists without
significant conflicts of interest.
¾ The focus on reducing threats from climate, and
other environmental, variability and change should
be resource-based, and with a local and regional
vulnerability perspective to start with (i.e., a
"bottom-up assessment). Policy actions which
optimize the entire spectrum of benefits for society
and the environment should be the goal.
