Scientists were eventually cleared in the 2009 "climate-gate" email fiasco, but the anonymous hacker who stole the emails is back for round two: he has posted a new batch of email online, many of them written by the same scientists, addressing the same issues, and carrying the same tone. The University of East Anglia has confirmed that some of the emails are authentic and says it believes they were stolen in the same breach that led to the earlier release. Climate scientists believe the release is intended to derail a climate-change conference in Copenhagen.
