VOICE ONE:
The stolen materials intensified questions about global warming. Are climate changes real? If so, were human activities mainly to blame? Most scientists involved in climate research answer "yes" to both questions. Even opposing scientists say human-influenced global warming has become widely accepted by the scientific community.
Some scientists, however, do not believe the evidence for warming. Or, they say the Earth may be warming, but human activity is not responsible.
Instead, these experts say, our planet is experiencing a normal series of temperature changes. They say such changes are events that have always happened.
VOICE TWO:
American researcher Patrick Michaels questions the evidence supporting human-influenced global warming. He said the stolen e-mails prove that the evidence is not correct.
Critics also noted an e-mail written more than ten years ago by Professor Jones of the C.R.U. In the e-mail, he used the words "trick" and "hide the decline" when writing about a graph showing rising temperatures. The image appeared in several scientific publications.
The critics say his wording showed purposeful misrepresentation. But other experts offered technical explanations of how the wording was not meant to hide a drop in temperatures. They say the word "trick" can mean a shortened and effective way to express complex findings.
