UK Police Close 'Climategate' Investigation British police say they're closing their investigation into the emails stolen from the University of East Anglia's Climatic Research Unit in 2009. The theft, dubbed "Climategate" by some, rattled the climate science community in the run-up to the failed U.N. climate talks in Copenhagen, Denmark. Norfolk Constabulary Det. Chief Supt. Julian Gregory said in a statement Wednesday his officers "do not have a realistic prospect of identifying the offender or offenders and launching criminal proceedings within the time constraints imposed by law." The force said police believe that the breach - which led to the publication of several thousand emails - was the result of an attack by a malicious hacker, not a whistleblower.
