A new UN report says that governments across the world have not yet committed to cut enough carbon dioxide emissions, putting the world on track for an increase of 2.5 degrees Celsius in global temperatures by the end of the century, far above the targeted 1.5-degree increase.

The UN Climate Change secretariat made a warning in a report released on Wednesday analyzing the reduction pledges presented by 193 countries and regions by late September.

The report says the combined pledges could put the world on track for a 2.5-degree increase in average global temperatures compared to preindustrial levels.

The report also shows that the current reduction commitments will see emissions increase by 10.6 percent by 2030, compared to 2010 levels.

Governments across the world agreed last year that they would work toward a goal of limiting the rise in global temperatures to 1.5 degrees by the end of the century.

To meet that goal, scientists say that carbon dioxide emissions need to be cut 45 percent by 2030.

The UN Climate Change secretariat says that the world is "still nowhere near the scale and pace of emission reductions required to put us on track toward a 1.5- degree Celsius world. To keep this goal alive, national governments need to strengthen their climate action plans now and implement them in the next eight years."

The next UN climate conference, called COP 27, is due to open on November 6th in Egypt.
