Obama science officials defend warming research

Obama science officials

Top White House science officials defended the validity of global warming research against repeated Republican attacks Wednesday that cited leaked e-mails from some climate researchers. The e-mails from a British university's climate center were obtained by computer hackers and released last month. Climate change skeptics contend the messages reveal that researchers manipulated and suppressed data and stifled dissent. At a congressional hearing, the president's science adviser and the chief of the agency in charge of climate research said the e-mails did nothing to undermine scientific consensus on climate change. Some Republicans said they showed a "culture of corruption" among scientists.
