Scientists project global carbon emissions will reach another record high by the end of 2018, spiking 2.7 percent to 37.1 billion tons released this year. That's up from last year's increase of 1.6 percent. The U.S. is the second highest single-country producer of carbon emissions, coming in at about 6 billion tons in 2018, behind China's 10 billion. America's 2.5 percent increase in emissions output comes amid the Trump administration's resistance to carbon-fighting policies. Global emissions saw a relatively flat period between 2014 and 2016, and American emissions had remained largely stable and even decreased since the early 2000s. These positive findings led scientists to believe efforts to fight emissions might be working, but Wednesday's findings squashed those hopes.
