'Bad news': CO2 emissions to rise in 2018, says IEA chief

Energy sector carbon emissions will rise in 2018 after hitting record levels the year before, dimming prospects for meeting Paris climate treaty goals, the head of the International Energy Agency (IEA) said Wednesday. The energy sector accounts for 80 percent of global CO2 emissions, with most of the rest caused by deforestation and agriculture, so its performance is key to efforts to rein in rising world temperatures. With one degree Celsius of warming so far, Earth has seen a crescendo of deadly extreme weather, including heatwaves, droughts, floods and deadly storm surges made worse by rising seas.
