Subject: Open letter to the climate science community
Dear colleagues and friends,
I am sure that by now, all of you are aware of the hacking incident which
recently took place at the University of East Anglia's Climatic Research
Unit (CRU). This was a criminal act. Over 3,000 emails and documents were
stolen. The identity of the hacker or hackers is still unknown.
The emails represented private correspondence between CRU scientists and
scientists at climate research centers around the world. Dozens of the
stolen emails are from over a decade of my own personal correspondence with
Professor Phil Jones, the Director of CRU.
I obtained my Ph.D. at the Climatic Research Unit. I went to CRU in 1983
because it was - and remains - one of the world's premier institutions for
studying the nature and causes of climate change. During the course of my
Ph.D., I was privileged to work together with exceptional scientists - with
people like Tom Wigley, Phil Jones, Keith Briffa, and Sarah Raper.
After completing my Ph.D. at CRU in 1987, I devoted much of my scientific
career to what is now called "climate fingerprinting", which seeks to
understand the causes of recent climate change. At its core, fingerprinting
is a form of what people now call "data mining" - an attempt to extract
information and meaning from very large, complex climate datasets. The
emails stolen from the Climatic Research Unit are now being subjected to a
very different form of "data mining". This mining is taking place in the
blogosphere, in the editorial pages of various newspapers, and in radio and
television programs. This form of mining has little to do with extracting
meaning from personal email correspondence on complex scientific issues.
This form of mining seeks to find dirt - to skew true meaning, to distort,
to misrepresent, to take out of context. It seeks to destroy the reputations
of exceptional scientists - scientists like Professor Phil Jones.
I have known Phil for over 25 years. He is the antithesis of the secretive,
"data destroying" character being portrayed to the outside world by the
miners of dirt and disinformation. Phil Jones and Tom Wigley (the second
Director of the Climatic Research Unit) devoted significant portions of
their scientific careers to the construction of the land component of the
so-called "HadCRUT" dataset of land and ocean surface temperatures. The U.K.
Meteorological Office Hadley Centre (MOHC) took the lead in developing the
ocean surface temperature component of HadCRUT.
The CRU and Hadley Centre efforts to construct the HadCRUT dataset have been
open and transparent, and are documented in dozens of peer-reviewed
scientific papers. This work has been tremendously influential. In my
personal opinion, it is some of the most important scientific research ever
published. It has provided hard scientific evidence for the warming of our
planet over the past 150 years.
Phil, Tom, and their CRU and MOHC colleagues conducted this research in a
very open and transparent manner. Like good scientists, they examined the
sensitivity of their results to many different subjective choices made
during the construction of the HadCRUT dataset. These choices relate to such
issues as how to account for changes over time in the type of thermometer
used to make temperature measurements, the thermometer location, and the
immediate physical surroundings of the thermometer. They found that, no
matter what choices they made in dataset construction, their bottom-line
finding - that the surface of our planet is warming - was rock solid. This
finding was supported by many other independent lines of evidence, such as
the retreat of snow and sea-ice cover, the widespread melting and retreat of
glaciers, the rise in sea-level, and the increase in the amount of water
vapor in the atmosphere. All of these independent observations are
physically consistent with a warming planet.
Extraordinary claims demand extraordinary proof. The claim that our Earth
had warmed markedly during the 20th century was extraordinary, and was
subjected to extraordinary scrutiny. Groups at the National Climatic Data
Center in North Carolina (NCDC) and at the Goddard Institute for Space
Studies in New York (GISS) independently attempted to reproduce the results
of the Climatic Research Unit and the U.K. Meteorological Office Hadley
Centre. While the NCDC and GISS groups largely relied on the same primary
temperature measurements that had been used in the development of the
HadCRUT dataset, they made very different choices in the treatment of the
raw measurements. Although there were differences in the details of the
three groups' results, the NCDC and GISS analyses broadly confirmed the
"warming Earth" findings of the CRU and MOHC scientists.
Other extraordinary claims - such as a claim by scientists at the University
of Alabama that Earth's lower atmosphere cooled since 1979, and that such
cooling contradicts "warming Earth" findings - have not withstood rigorous
scientific examination.
In summary, Phil Jones and his colleagues have done a tremendous service to
the scientific community - and to the planet - by making surface temperature
datasets publicly available for scientific research. These datasets have
facilitated climate research around the world, and have led to the
publication of literally hundreds of important scientific papers.
Phil Jones is one of the gentlemen of our field. He has given decades of his
life not only to cutting-edge scientific research on the nature and causes
of climate change, but also to a variety of difficult and time-consuming
community service activities - such as his dedicated (and repeated) service
as a Lead Author for the Intergovernmental Panel on Climate Change (IPCC).
Since the theft of the CRU emails and their public dissemination, Phil has
been subjected to the vilest personal attacks. These attacks are without
justification. They are deeply disturbing. They should be of concern to all
of you. We are now faced with powerful "forces of unreason" - forces that
(at least to date) have been unsuccessful in challenging scientific findings
of a warming Earth, and a "discernible human influence" on global climate.
These forces of unreason are now shifting the focus of their attention to
the scientists themselves. They seek to discredit, to skew the truth, to
misrepresent. They seek to destroy scientific careers rather than to improve
our understanding of the nature and causes of climate change.
Yesterday, Phil temporarily stepped down as Director of the Climatic
Research Unit. Yesterday was a very sad day for climate science. When the
forces of unreason win, and force exceptional scientists like Professor Phil
Jones to leave their positions, we all lose. Climate science loses. Our
community loses. The world loses.
Now, more than at any other time in human history, we need sound scientific
information on the nature and causes of climate change. Phil Jones and his
colleagues at CRU have helped to provide such information. I hope that all
of you will join me in thanking Phil for everything he has done - and will
do in the future - for our scientific community. He and his CRU colleagues
deserve great credit.
With best regards,
Ben Santer

The hackers seem to have stolen bad info and now are disseminating it
as truth that was covered up until now. If you live in my part of the
world you will notice we are having warmer weather every
year and the weather-casters are getting stumped more and more often
as they miss predictions by wide margins They always estimate too low.
As far as spraying ocean water to cool off the arctic etc, I think it
will rake a lot less resources to seed the clouds with small amounts
of iodide or other substances with the same effect. Dry ice is too
bulky but its a renewable resource. I still say we can cool off the
gulf stream and the winds blowing up from the south.

Global Warming was not a topic that I generally gave much thought
until the release of FOI2009.zip into the wild. Yes, I have a copy.
BTW, if I were investigating the leak, I would be looking to the
people who have administrative access to the mail servers and other
servers that had copies of the documents. I assume the log files are
still available for user log ins. sudo also keeps logs.
Anyway, I saw a tweet about ESR talking about the CRU (which I had no
knowledge of at the time). So my first experiences were from the
skeptics on AGW. Well I'm a skeptic myself. I didn't simply stop
there. Serious accusations were made and they too have to be proven. I
ended up looking at realclimate.org, 350.org, and other resources.
Resources I was not previously aware of.
The evidence for AGW has become more compelling in my mind.
So regardless of the harm caused by FOI2009.zip being set free, it is
not all bad. I bet I'm not the only new person thinking about AGW
seriously now. Before December, I didn't even know what AGW was. Sure,
I had heard of the green house effect. I knew there was debate on
global warming. But I didn't think about it.
I'm sure I'm not the only one to start thinking about the CO2. Heck, I
always thought volcanoes produced more of it than human activity did.
So much for that idea:
