Here is the text of the invitation:

You are invited to attend a luncheon briefing this Wednesday on Understanding Changes in Earth’s Temperature and Climate. The briefing is sponsored by the University Corporation for Atmospheric Research (UCAR) and presented with the assistance of the Senate Commerce, Science and Transportation Committee. Please feel free to forward this invitation to the appropriate staff in your office, and we hope to see you Wednesday.

Missing the Hockey Season? Come to this Briefing!

Understanding Changes in Earth’s Temperature and Climate:

The Science Behind the Hockey Stick Graphs and Model Simulations


Wednesday, April 6

11:30 a.m., Room 253, Senate Russell Building

The NHL may have cancelled their season, but this briefing is on!! The "hockey stick" graphs, which show how global temperatures have varied over the last 1000 years, are at the center of a public debate on how humans are affecting the Earth’s climate. Named for their characteristic
shape-a downward trending "shaft" from 1000 to 1900 A.D. followed by an upward-trending 20th century "blade"-the hockey stick became an icon for the Intergovernmental Panel on Climate Change’s (IPCC) conclusion that humans are partially responsible for a century’s worth of rising global temperatures. But this conclusion was based on much more information than the hockey stick graphs, including theoretical considerations, model simulations, and instrumental observations. Many of these topics will be addressed at the briefing.

How do we know with any certainty what the temperature was 1000 years ago and that the recent spike is caused by humans? How can we predict with any certainty what temperatures will be in the future? What are the causes for observed climate variations and the evidence for recent
climate change? How do global temperatures relate to changes in a particular region? Please join us to learn the answers to these and other questions from some of the world’s most respected climate scientists. Following presentations, you will have the opportunity to ask questions of and discuss climate issues with this distinguished panel.

Briefing Speakers:

* Ray Bradley — Director of the Climate System Research Center at
the University of Massachusetts, Amherst and a University
Distinguished Professor in the Department of Geosciences, Dr.
Bradley is a renowned climate scientist who has written and edited
ten books on climate science. He has been an advisor to various
governments and international agencies and is active in the IPCC
* Tom Crowley — Nicholas Chair of Earth Systems Science in the
Nicholas School of the Environment, Duke University, Crowley is an
esteemed scholar of climate science. His experience includes
private sector work as well as former director of the National
Science Foundation’s Climate Dynamics Program, and NASA research
*Caspar Ammann – An outstanding young scientist in the Climate
and Global Dynamics Division of the National Center for
Atmospheric Research (NCAR), Dr. Amman has received honors and
fellowships from the National Science Foundation and Earth Systems
History. He has been elected to the Editorial Advisory Board for
the Encyclopedia of Paleoclimatology.

    Did you or Ross get invited to the hockey game Steve?
    I would love to be at the after-match analysis – how to explain an own-goal!

    Did Ray Bradley and Tom Crowley turn up wearing a new fashion statement: invisible clothes?

    No. There’s a tape of this conference up at UCAR.
