Carbon emissions up as Trump agenda rolls back climate change work

Last year's 3.4% jump in emissions is the largest since 2010 recession and second largest gain in more than two decades

A new analysis shows US greenhouse gas levels are increasing as the Trump administration unravels efforts to slow climate change.

Carbon emissions rose sharply last year, increasing 3.4%, according to new estimates from the economic firm Rhodium Group. That year's jump in emissions is the biggest since the bounce back from the recession in 2010. It is the second largest gain in more than two decades.
