London ? An independent report into the leak of hundreds of e-mails from one of the world’s leading climate research centers on Wednesday largely vindicated the scientists involved, saying they acted honestly and that their research was reliable.

But the panel of inquiry, led by former U.K. civil servant Muir Russell, did chide scientists at the University of East Anglia’s Climatic Research Unit for failing to share their data with critics.

“We find that their rigor and honesty as scientists are not in doubt,” Russell said. “But we do find that there has been a consistent pattern of failing to display the proper degree of openness.”

Russell’s inquiry is the third major U.K. investigation into the theft and dissemination of more than 1,000 e-mails taken from a back-up server at the university.
