Global carbon pollution rises

WASHINGTON — Global carbon pollution rose this year after three straight years when levels of the heat-trapping gas didn't go up at all, scientists reported Monday.

Preliminary figures project that worldwide carbon dioxide emissions are up about 2 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. We haven't," 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.

Estimates for 2017 put it at about 40.8 billion tons. Sixty years ago, the world spewed only 9.2 billion 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 percent of global warming since 1950, U.S. scientists reported this month.

This year's 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 2 percent.

The 2017 estimate comes to on average of 2.57 million pounds of carbon dioxide spewing into the air every second.

The study was published Monday and is being 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 2 degrees Celsius (3.6 degrees Fahrenheit) since preindustrial times, but it's 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 wasn't 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 — which produces these reports every year in November — 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.

Tenant charged with homicide in July Flagstaff rent dispute

A Flagstaff man who fatally stabbed his landlord during a rent dispute has been charged with murder, three months after the incident.

James Womble, 21, has been charged with one count of second-degree murder after stabbing Peter Gillespie, 63, on July 25. He pleaded not guilty to the charge and is claiming self-defense.

Womble was released to pre-trial services under his own recognizance, meaning that he will remain out of jail without having to post bail.

The charges brought a sense of relief to Gillespie’s longtime friend Marilyn Reuvers, who has been skeptical of the self-defense claim that Womble made to Flagstaff police in July.

“I am excited they actually charged someone and I hope they follow through with a trial,” Reuvers said.

The Coconino County Attorney’ Office which delayed charging Womble until it received all of the forensic evidence from the Department of Public Safety Crime Lab.

Another friend of Gillespie, Paul Deasy, also said the charges brought a sense of relief.

However, Reuvers said she was upset that Womble will not await his trial in jail.

“I don’t like the fact that he is out. He doesn’t deserve to be out,” Reuvers said. “But at least he has been charged.”

Gillespie was killed after he got into an altercation with Womble over past-due rent. The incident ended with Womble stabbing him eight times with a pair of scissors, according to the report filed by Flagstaff police.

Gillespie was stabbed with in the neck, chest, leg, left shoulder and left forearm. The coroner’s report was signed by the Coconino County Medical Examiner, Lawrence Czarnecki, who labeled multiple stab wounds as the cause of death and the manner of death a homicide.

Womble called 911 after the incident and admitted to stabbing his landlord; however, Womble told police he only stabbed Gillespie after being attacked.

He said the incident became violent after Gillespie bumped him and threw him to the ground, causing his shoulder to go out of socket. However, Womble also stated that his shoulder pops out of place often, stemming from a past injury.

Womble then claimed he grabbed a pair of scissors in self-defense, yelling at Gillespie to “get away from me. I am going to stab you. I have a bad shoulder and I can’t do anything else but stab, so please get away from me.”

According to Womble, Gillespie then began to choke him, causing Womble to stab Gillespie eight times.

Womble is scheduled to appear in court for his preliminary hearing on Dec. 8. His attorney Adam Zickerman did not respond to a request for comment.
