HONOLULU -

Scientists from the University of Hawaii were involved in new research explaining why global warming has slowed down dramatically since the turn of the century.

Since 1950, global temperatures have increased at a rate of one-fourth of a degree Fahrenheit, per decade.

This rise stopped around the year 2000, despite a continuing, steady rise in carbon dioxide, which is the main greenhouse gas produced by humans.

This slow down is due to a cooling of eastern Pacific Ocean waters, according to UH's primary researcher on the project, Shang-Ping Xie, who worked closely with the Scripps Institution of Oceanography at UC San Diego.

"Based upon the instrumental climate records we have over the past 130 years, we saw similar events of equa-tropical Pacific cooling and eventually these past events come out from the cool state," Xie said.

Researchers said they don't know when this will happen, but said when warming begins again, it will resume with a vengeance.
