Global carbon pollution rose this year after three straight years when emissionsof the heat-trapping gas did not go up at all, scientists reported Monday.

Preliminary figures project that worldwide carbon dioxide emissions are up about 2 per cent this year, according to an international team of scientists. Most of the increase came from China.

The report by the Global Carbon Project team dashed hopes that emissions from the burning of coal, oil and gas had peaked.

"We hoped that we had turned the corner... We have not," said study co-author Rob Jackson, an Earth scientist at Stanford University.

Carbon dioxide emissions rose steadily and slowly starting in the late 1880s with the Industrial Revolution, then took off dramatically in the 1950s. In the last three years, levels had stabilized at about 36.2 billion tonnesof carbon dioxide (40 billion tons).

'A bit staggering'

Estimates for 2017 put it at about 37 billion metric tonnes (40.8 billion tons). Sixty years ago , the world spewed only 8.3 billion tonnes(9.2billion tons).

"It's a bit staggering," said co-author Ralph Keeling, a Scripps Institution of Oceanography scientist, noting in an email that levels have increased fourfold since he was born in the 1950s. "We race headlong into the unknown."

Man-made carbon dioxide is causing more than 90 per cent of global warming since 1950, U.S. scientists reported this month.
