Chronicle: Michael Mann is a prominent climate researcher whose speciality is reconstructing Earth’s past climate. Ken Cuccinelli is Virginia’s attorney general. Leaked e-mails between Mann and his fellow researchers appeared to suggest that they were misrepresenting their research to support the case that humans are changing Earth’s climate. In response to what became known as climategate, Cuccinelli, a climate change skeptic, demanded earlier this month that the University of Virginia hand over the research records that Mann kept there before he moved last year to Pennsylvania State University. Now, the University of Virginia has petitioned a state court to overturn the AG’s demand.
