Global carbon pollution rises after three straight flat years

By Seth Borenstein

The Associated Press

WASHINGTON ó Global carbon pollution rose this year after three straight years when levels of the heat-trapping gas didnít go up at all, scientists have reported.

Preliminary figures project that worldwide carbon dioxide emissions are up about two percent 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 Ö We havenít," 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 40 billion tons of carbon dioxide (36.2 billion metric tons).

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

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

Manmade carbon dioxide is causing more than 90 percent of global warming since 1950, U.S. scientists reported.

This yearís increase was mostly spurred by a 3.5 percent jump in Chinese carbon pollution, said study co-author Glen Peters, a Norwegian scientist. Declines in the United States (0.4 percent) and Europe (0.2 percent) were smaller than previous years. India, the No. 3 carbon polluting nation, went up two percent.

The 2017 estimate comes to an average of 2.57 million pounds (1.16 million kilograms) of carbon dioxide spewing into the air every second.

The study was published and presented in Bonn, Germany, during climate talks where leaders are trying to come up with rules for the 2015 Paris deal. The goal is to limit temperature rise to 2ļ Celsius (3.6ļ Fahrenheit) since preindustrial times, but itís already warmed half that amount.

"It was tough enough and if this paper is indicative of long-term trends, it just got tougher," said Princeton University climate scientist Michael Oppenheimer, who wasnít part of the team of 76 scientists who wrote the report.

While he called the study authoritative, Pennsylvania State University climate scientist Michael Mann said he sees no need to do figures for 2017 that are not complete, saying it may be "jumping the gun a bit."

Jackson said the team ó which produces these reports every year in November ó has confidence in its 2017 report because it is based on real data from top polluting nations through the summer and in some cases through October. Plus, he said past estimates have been correct within a couple tenths of a percentage point.

The top five carbon polluting countries are China, the United States, India, Russia, and Japan. Europe, taken as a whole, would rank third.
