Anglia's Hadley Climatic Research Unit was hacked, and internal documents released. Some discussion and analysis of the leaked items can be found at Watts Up With That. The CRU has confirmed that a breach occurred, but not that all 61 MB of released material
is genuine. Some of the emails would seem to raise concerns about the science as practiced — or at least beg an explanation. From the Watts
Up link:

"[The CRU] widely recognized as one of the world's leading
institutions concerned with the study of natural and anthropogenic
climate change. Consisting of a staff of around thirty research
scientists and students, the Unit has developed a number of the data
sets widely used in climate research, including the global temperature
record used to monitor the state of the climate system, as well as
statistical software packages and climate models. An unknown person put
postings on some climate skeptic websites that advertised an FTP file
on a Russian FTP server. Here is the message that was placed on the Air
Vent today: 'We feel that climate science is, in the current situation,
too important to be kept under wraps. We hereby release a random
selection of correspondence, code, and documents' The file was large,
about 61 megabytes, containing hundreds of files. It contained data,
code, and emails apparently from the CRU. If proved legitimate, these
bombshells could spell trouble for the AGW crowd."

Anyone surprised?
