CO2 Surge in US Emissions
A three-year decline in the amount of carbon dioxide being spewed into the atmosphere by the United States ended in 2018 with a surge that saw emissions rise by 3.4 percent.
Data collected by an independent economic research firm found it was the largest rise in carbon emissions in the country in eight years.
A report by the Rhodium Group said the spike occurred even though a record number of U.S. coal-fired power plants closed last year.
But prolonged cold spells in many areas and a hot summer increased demand for air conditioning and heating, fueling the surge.
