World’s chief scientist disputes U.S. stance on global warming

BUENOS AIRES, Argentina – The world’s chief climate scientist on Tuesday disputed the U.S. government contention that cutbacks in carbon dioxide emissions are not yet warranted to check global warming.

Experts readied a report, meanwhile, saying 2004 will be one of the warmest years on record.

“The science says you’ve got to reduce emissions,” Rajendra K. Pachauri told The Associated Press in an interview midway through a two-week international climate conference.

The Kyoto Protocol, the international accord requiring cuts in carbon dioxide, “is driven by the need to reduce emissions, and on that there is no question,” said Pachauri, chairman of a U.N.-sponsored network of climatologists.

Scientists largely blame the accumulation of carbon dioxide and other “greenhouse gases” in the atmosphere for the rising temperatures of the past century.

The 10 warmest years globally, since records were first kept in the 19th century, have all occurred since 1990, the top three since 1998.
