Global emissions of the greenhouse gas carbon dioxide notched up 1.4 percent to 31.6 gigatonnes in 2012, a move in the opposite direction of an international climate goal to limit global warming, the International Energy Agency said in a report released Monday.

Instead of limiting warming to a long-term rise of no more than 3.6 degrees Fahrenheit (2 degrees Celsius), the report said the world is currently on a path toward a rise of as much as 9 degrees Fahrenheit (5.3 degree Celsius) above pre-industrial levels.

Such a rise would come “with potentially disastrous implications in terms of extreme weather events, rising sea levels, and the huge economic and social costs that these can bring,” Maria van der Hoeven, executive director of the International Energy Agency, said at the report’s launch.
