A new study from the International Energy Agency says emissions of carbon dioxide from fossil fuels rose to record levels last year. Global emissions increased by 1.4 percent, putting the world on pace for a temperature hike of up to 5.3 degrees Celsius, or 9 degrees Fahrenheit, which is more than double the 2-degree-Celsius target set by world leaders. The agency’s chief economist called that scenario a “disaster for all countries.”
