WASHINGTON (AP)—Scientists calculate that global emissions of heat-trapping carbon dioxide saw their largest rise in seven years.
Projections show world carbon dioxide emissions increased 2.7 percent from 2017 to 2018, following several years of little growth. The calculations are from the Global Carbon Project, an international scientific collaboration of academics, governments and industry that tracks greenhouse gas emissions. They were published in three scientific journals Wednesday.
The new figures were announced as government leaders meet in Poland to negotiate how to put the 2015 Paris climate accord into effect. Scientists say the estimate puts some of the landmark agreement's goals nearly out of reach.
The studies say this year the world is spewing 40.9 billion tons (37.1 billion metric tons) of carbon dioxide.
Global Carbon Project chairman Rob Jackson calls it discouraging.
