If the world's population continues to live up to the present, the temperature would threaten to rise by 3.4 to 3.9 by the end of the century rather than by just 1.5 degrees above pre-industrial levels.
In the Paris Climate Agreement, almost all countries in the world have set limits to significantly less than two degrees of global warming compared to pre-industrial times – many states and experts consider the 1.5 degree target necessary. By just one degree, the earth has already warmed up.
Countries need to significantly adjust their nationally-defined contributions in the coming year to close the gap in climate targets with policies and strategies, the UNEP report said. Even if all states actually deliver their currently defined contributions, 2030 will still be emitting 32 gigatons of CO2 too much to reach the 1.5-degree target.
From 2 to 13 December, representatives from 200 countries will meet at the UN Climate Change Conference in Madrid to debate the fight against global warming.
